Enchanting

Enchanting is a game mechanic that involves using an Enchantment Table to add special bonuses to tools, weapons or armor. To enchant an item, you need the required Experience level for the enchantment and an Enchantment Table. Each enchantment costs the player experience levels but in turn allows the player to enchant armor, swords and tools with one or several random bonus attributes as well as making the items glow with a brilliant hue.

[edit] Enchanting basics

To enchant an item, craft an Enchantment Table, place it on the ground, right-click on it and drag an enchantable item from your inventory onto the square under the book icon. Three randomly chosen enchantments will appear on the menu on the right. Enchantments that you can apply to an item will be highlighted, whereas unavailable enchantments will be grayed out.

The only thing you can know for sure about enchantments are their levels, which appear as a number; the foreign text is random. You can take the item off and place it on the table again for a different set of enchantments. Or, you can attempt to replace the item on the table with a stack of two or more of any other item from your inventory.

Once you choose an enchantment, it will be applied to your item, giving it a glow and one of the special powers detailed below, and you will lose a number of experience levels equal to the level of the enchantment. Enchantments cannot be undone and an item can only be enchanted once, although the item may receive multiple enchantments during one instance of enchanting, determined randomly.

Whenever you place an eligible item on the table, the enchantment levels available are randomly generated for each slot using the formula below. The enchantment level is dependent upon the number of nearby bookshelves (capped at 30) and a "slot factor" of 0.50 for the topmost enchantment slot, 0.66 for the middle slot, and 1.00 for the bottom slot. (If the number of bookshelves is 0, the second two random integers will always be zero. When placing bookshelves around the Enchanting Table they CANNOT be touching the table or the table will not change from 5.)

Enchantment level available = (1..5 + (b/2) + 0..b) × s,

where b is the number of nearby bookshelves (maximum of 30), s is the slot factor for the given enchantment slot, and x..y generates a uniformly distributed random integer between x and y inclusive. The lowest level available is equal to half the number of book shelves used.

Prior to version 1.1, the (b/2) term in the above equation was 0..(b/2), resulting in more randomness, and making the search for high level enchantments an extremely time consuming process. Prior to 1.1, the lowest level available was 1, regardless of the number of bookshelves used.

Bookshelves	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25	26	27	28	29	30
Min Level	1	1	2	2	2	2	3	3	3	3	4	4	4	4	5	5	5	5	6	6	6	6	7	7	7	7	8	8	8	8	8
Max Level	5	6	8	9	11	12	14	15	17	18	20	21	23	24	26	27	29	30	32	33	35	36	38	39	41	42	44	45	47	48	50

In Creative mode, no levels or xp are necessary for enchantments.

[edit] Bookshelf placement

Nearby bookshelves raise the available enchantment levels. As of Beta 1.9 Pre-release 4, no enchantments costing above five Experience levels are available unless you place bookshelves near but not touching the Enchantment Table.

In order to have an effect, a bookshelf must be placed exactly 2 blocks, laterally, off the enchantment table and be on the same level or one block height above the table, and the space between the bookshelf and table must be Air (even a torch or snow cover will block the effect), where “between” is as shown in the following diagrams (the white spaces are air, and the do not matter):

Like this from the top:		or
and like this from the side:		or

An enchantment table can be surrounded by 30 bookshelves by placing them in a square around the table, with each wall measuring 5 blocks wide and 2 blocks high, with a 2 block high doorway. This arrangement gives the maximum possible boost.^[1] (While it is possible to get two more bookshelves in "range", they do not add, as the boost is capped.)

An easy way to limit the maximum level of enchantment available, if you want to do a lower-level enchantment, is to put torches on the bookshelves so that they aren't recognized by the enchantment table. That way you can still have the entire 'ring' of bookshelves around the table, but get lower-level enchantments when you need them. Breaking the torches will restore the maximum level to its original amount.

An important thing to remember is to keep the area between the enchanting table and the bookshelves completely clear. Things like snow can cancel out the effect of all the bookshelves, and will render them useless until the snow is cleared. A safe bet is to completely clear the workspace unless you are intentionally doing so to obtain lower level enchantments.

[edit] Enchantments

Enchantment names are randomly constructed from the following list of words. Three to five words are chosen from the list and appended to each other, then displayed in the Standard Galactic Alphabet. Note that the names have no meaning and are not saved on the enchanted item (meaning they will tell you nothing about what the resulting spell will be), and they are only displayed in the Enchantment Table interface.

The following list of words contain all the possible enchantment words after de-ciphered from the Standard Galactic Alphabet.

scrolls klaatu berata niktu xyzzy bless curse light darkness fire air earth water hot dry cold wet elder ignite snuff embiggen twist shorten stretch fiddle destroy imbue galvanize enchant free limited range of the towards inside sphere cube self other ball mental physical grow shrink demon elemental spirit animal creature beast humanoid undead fresh stale

Repairing an enchanted weapon/tool will remove the enchantment on it.^[2]

When an enchanted weapon deals bonus damage to a mob, circular blue particles fly off of that mob, similar to getting a critical hit.

There are several levels on most enchants, and when you enchant you can get several enchants on each weapon/tool/armor.

[edit] Enchantable Items

Items such as swords, shovels, pickaxes, axes, bows, and every part of armor of any material can be enchanted. Hoes, shears, fishing rods and flint and steel are not enchantable.

[edit] Enchantment Types

EID is the item's Effect Identification Number in the game code.

EID	Enchantable item/s	Name	Effect type	Max. Enchantment Power	Per-level bonus	Notes
[edit] Armor Enchantments
0		Protection	Converts all damage from all sources (except from The Void and the /kill command) to armor damage.	IV		Armor with this enchantment cannot receive any other type of Protection, apart from helmets, which can receive the Respiration and Aqua Affinity enchantments and boots which can receive feather falling.
1		Fire Protection	Protection against fire	IV		Armor with this enchantment cannot receive any other type of Protection, apart from boots, which can receive the Feather Falling Enchantment.
2		Feather Falling	Less fall damage	IV	+1 to reduction of falling damage (half a heart)	This is a great way to prevent the fall damage from Ender Pearl teleportations.
3		Blast Protection	Protection against explosions	IV		Armor with this enchantment cannot receive any other type of Protection, apart from boots, which can receive the Feather Falling Enchantment.
4		Projectile Protection	Protection against projectile entities (e.g. arrows).	IV		Armor with this enchantment cannot receive any other type of Protection, apart from boots, which can receive the Feather Falling Enchantment.
5		Respiration	Decreases the rate of air loss underwater; increases time between damage while suffocating.	III	Underwater breathing time +15 seconds; time between suffocation damage +1 second.
6		Aqua Affinity	Increases underwater mining rate	I
[edit] Sword Enchantments
16		Sharpness	Extra damage	V	Up to 1.5 hearts extra damage per level.	Extra damage is random for every hit, but will always be at least 0.5 heart. A sword with this enchantment cannot receive Smite or Bane of Arthropods.
17		Smite	Extra damage to zombies, zombie pigmen, and skeletons.	V	Up to 2 hearts extra damage per level.	Extra damage is random for every hit, but will always be at least plus 0.5 heart. A sword with this enchantment cannot receive Sharpness or Bane of Arthropods.
18		Bane of Arthropods	Extra damage to spiders, cave spiders and silverfish.	V	Up to 2 hearts extra damage per level.	Extra damage is random for every hit, but will always be at least 0.5 heart. A sword with this enchantment cannot receive Sharpness or Smite.
19		Knockback	Increases the knockback dealt when attacking mobs and players.	II	More knockback.	Does not stack with knockback caused by attacking while sprinting. Note that this enchantment can sometimes make experience harder to obtain, as it knocks the mob's body back, causing the orbs to spawn farther away.
20		Fire Aspect [note 1]	Lights the target on fire	II	Affects duration of burning.	Will cook meat if mob is killed by the fire damage.
21		Looting	Mobs have a chance to drop more loot.	III	+1 to max loot drop per level.	This also increases the chance of getting a rare drop.
[edit] Tool Enchantments
32		Efficiency	Faster resource gathering while in use.	V	+50% mining speed.	Efficiency V gives a 250% speedboost, breaking some blocks instantly. The speed increase applies to blocks that the tool is appropriate for and those that can be mined by hand.
33		Silk Touch [note 2] [note 3]	Blocks mined will drop themselves, even if it should drop something else (e.g. Stone will drop stone, not Cobblestone).	I		Allows the collection of normally unobtainable blocks such as Ores, Grass, Mycelium and Huge Mushrooms. The normal requirments for mining blocks still applies: e.g. An iron or better pickaxe must still be used to retrieve diamond ore blocks etc.
34		Unbreaking	At each use, there's a chance the tool's durability will not decrease.	III	The tool will last an entire tool durability longer.	For example, an Unbreaking III item has a chance to use up a use of (100/(3+1))% = (100/4)% = 25%, so Unbreaking III should, on average, make a tool last 4 times as long.
35		Fortune [note 4]	Can multiply the drop rate of items from blocks	III	I: 30% * 2 (30% more) II: 25% * 2, 25% * 3 (75% more) III: 20% * 2, 20% * 3, 20% * 4 (120% more)	Only applies to item drops such as coal, diamond, redstone, lapis lazuli and nether wart. When used on wheat, only the seeds' drop rate is affected. If used on Tall Grass the seeds drop rate is also increased. Increases the chance for gravel to drop flint instead of itself, up to 100% at III. It doesn't affect clay ball drop rates (it is always 4). Also increases the drop rate of apples from trees.
[edit] Bow Enchantments
48		Power	Extra damage	V	Extra damage is dealt	Multiplies base damage by 1.5 at Power I. Additional levels increase the multiplier by .25 each for a maximum of 2.5. At Power V and with the bow fully drawn it will kill most mobs with a single shot (11-12.5 hearts damage).
49		Punch	Knockback effect on mobs	II	Mobs are knocked back farther.
50		Flame	Sets arrows and mobs on fire.	I		Sets arrows on fire when shot, and mobs when hit.
51		Infinity	Gives infinite shots with a single arrow.	I		This can be extremely useful against the Ender Dragon when fighting it in The End, since the player can no longer return for more arrows to use. However, arrows fired by a bow with this enchantment cannot be retrieved, similar to the arrows fired by Skeletons.

[edit] How Enchantments Are Chosen

"Enchantment level" is the cost of the enchantment in experience levels (the green number on the button). "Enchantment power" is the strength of the particular enchantment. For example, "Sharpness IV" has power 4. The enchantment algorithm uses a three-step process.

[edit] Step One - Applying modifiers to the enchantment level

The first thing that Minecraft does is apply two modifiers to the base enchantment level. Each modifier is restricted to a certain range, with numbers close to the middle of the range more common than those near the ends.

The first modifier is based on the item's "enchantability," which depends on the material and the type of the item (see the table below). Minecraft picks a number between 0 and the enchantability, then adds that number plus one to the enchantment level. Bows have an enchantability of 1 for this purpose. This random value follows a triangular distribution (like rolling a pair of dice and adding) so results close to half the enchantability are much more likely than results at the extremes.

modified enchantment level = enchantment level + Random(0, enchantability) + 1

Material	Armor enchantability	Sword/Tool enchantability
Wood	N/A	15
Leather	15	N/A
Stone	N/A	5
Iron	9	14
Chain	12	N/A
Diamond	10	10
Gold	25	22

Next, Minecraft picks a value between 0.75 and 1.25, again with a triangular distribution. The modified enchantment level is multiplied by this value (so it could increase or decrease by up to 25%) and then rounded to the nearest integer.

[edit] Step 1 pseudocode

/* Returns a uniformly distributed random number between [0,n) */
function randomInt(n);

/* returns a uniformly distributed random number between [0,1) */
function randomFloat();

int j = item_enchantability
int i = chosen_enchantment_level
int j2 = 1 + randomInt(j/2 + 1) + randomInt(j/2 + 1);
int k = j2 + i;
float f = (randomFloat() + randomFloat() - 1) * 0.25;
int final_level = (int)((float)k * (1.0 + f) + 0.5);

Source:^[3]

[edit] Step Two - Find possible enchantments

Now, based on the modified level, Minecraft makes a list of all enchantment types that can be applied to the target item along with the power that each enchantment will have.

The power of each enchantment type is determined by the level and the values in the enchantments levels table. For each power value of an enchantment type, there is a minimum and maximum modified level that can produce the enchantment at that power. If the modified enchantment level is within the range, then the enchantment will be assigned that power. If the modified level is within two overlapping ranges for the same enchantment type, the higher power value is used.

[edit] Step Three - Select a set of enchantments from the list

Now that it has a list of the possible enchantments for the item, Minecraft must pick some of them that will actually be applied.

You always get at least one enchantment. The first enchantment is picked from a list of statistical "weights" - the enchantment with the higher weight has a higher chance of being selected.

P(enchantment) = (enchantment weight) / ( ∑i=1number of possible enchantments〖enchantment weighti 〗)

Armor Enchantments	Weight
Protection	10
Fire Protection	5
Feather Fall	5
Blast Protection	2
Projectile Protection	5
Respiration	2
Aqua Affinity	2
Sword Enchantments	Weight
Sharpness	10
Smite	5
Bane of Arthropods	5
Knockback	5
Fire Aspect [note 1]	2
Looting	2
Tool Enchantments	Weight
Efficiency	10
Silk Touch [note 2] [note 3]	1
Unbreaking	5
Fortune [note 4]	2
Bow Enchantments	Weight
Power	10
Punch	2
Flame	2
Infinity	1

After the first element is selected, there is a chance of receiving more, based on this algorithm:

1. Divide the modified level in half, rounded down. (This does not affect the possible enchantments themselves, because they were all pre-calculated in Step Two.)
2. With probability (modified level + 1) / 50, keep going. Otherwise, stop picking bonus enchantments.
3. Remove from the list of possible enchantments anything that conflicts with previously-chosen enchantments.
4. Pick one enchantment from the remaining possible enchantments (based on the weights, as before) and apply it to the item.
5. Repeat from step 1.

[edit] Conflicting Enchantments

Some enchantments conflict with other enchantments and thus both can't be enchanted into the same item, effectively taking down the possibility for one to get an overpowered weapon.

The rules for enchantment conflicts are:

• Every enchantment conflicts with itself. (So you can't get a tool with two copies of the Efficiency enchantment.)
• All protection enchantments conflict with each other, so an item can only have one at a time. (In the code, Feather Fall is implemented as a protection enchantment, but it doesn't conflict with the others.)
• All damage enchantments (Sharpness, Smite, and Bane of Arthropods) conflict with each other.
• Silk Touch and Fortune also conflict with each other. (The Silk Touch enchantment has no effect on a pickaxe that also has Fortune, such as could be obtained in a 1.9 pre-release or with an inventory editor, since a Silk Touch pickaxe cannot mine resources such as diamonds or coal—only their ore blocks.)

[edit] Enchantment Simulator

A website for testing and simulating enchantments can be found here.

[edit] Enchantment Probability Charts

A bunch of charts on the probabilities of different enchantments here.

[edit] Standard Galactic Alphabet

The enchantments are written in the Standard Galactic Alphabet which is a simple alphabet substitution cipher used in the Commander Keen series of computer games (see that page for the code key).

This is something that may help you decode the language (but will not give leads on the enchanting result):

[edit] Textures

The enchanting panel can be edited by the use of a texture packs. Modifying the file /gui/enchant.png in the desired texture pack will affect the background image and the textures displayed on the enchantment list when using the enchanting table in game. The book texture will appear as it does above the enchanting table.

The 'brilliant hue' applied to enchanted tools, weapons, and armour is also a modifiable texture, however the application is much more complex. The file /misc/glint.png (64x64 pixels) is blended with the standard enchanted purple color and then overlaid on all applicable in game images (in some cases several time with different rotations) with a continually changing vertical and horizontal offset. Therefore to create different effects, different patterns and colors can be used. White will give you the standard color and all other colors will appear with a hue shifted towards the higher end of the color spectrum. But, an entirely black image will remove all visual effects.

[edit] History

Notch first tweeted about the Enchantment Table on September 30th 2011.^[4]

Enchanting was added to the game in 1.9 prerelease 2. However, enchanting was not the same in the 1.9 prerelease 2. Enchanting did NOT require bookshelves to get maximum enchantments. Also, many enchantments were not added back then. Enchantments are labeled in the enchanting table as random words in the Standard Galactic Alphabet.

In 1.1, four bow enchantments (Power, Flame, Punch and Infinity) were added to the game.

As of snapshot 12w05a, enchanting no longer requires experience in creative mode.

As of snapshot 12w06a, Golden Swords and Bows have a small chance of being already enchanted when dropped by their respective mobs.

As of snapshot 12w17a, Ice and Glass Panes can again be collected with a Silk Touch-enchanted tool.

[edit] Notes

1. ↑ ^{a b} Fire Aspect enchantment is virtually useless on all Nether mobs because all nether mobs are immune to fire and lava.
2. ↑ ^{a b} Silk Touch does not work on Monster Spawners, Ice, or Glass Panes. (As of 12w17a though, Silk Touch does work on Ice and Glass Panes.)
3. ↑ ^{a b} Items able to be obtained legitimately only through use of Silk Touch:
   • Grass Block
   • Coal Ore
   • Lapis Lazuli Ore
   • Diamond Ore
   • Redstone Ore
   • Ice (as of 12w17a)
   • All huge mushroom blocks
   • Mycelium
4. ↑ ^{a b} Fortune on an axe will produce higher yields in Nether Wart and Melons (50% per level; 150% at Fortune III) Fortune on a shovel will produce flint from gravel at 100% and will produce higher yields in harvesting Nether Wart and Melons(50% per level; 150% at Fortune III) e.g. Average harvest of Nether Wart with nothing= ~3 Average harvest with Fortune 1= ~3.5 Average harvest with Fortune 3= ~4.5

[edit] Trivia

• Looting enchantment does not process on Wool, Spider Eye, Raw Chicken, and Cooked Chicken.
• Items that are enchanted will receive a glowing aura around them. Editing glint.png in .minecraft\bin\minecraft.jar\misc can change the glow accordingly. On past versions of Minecraft and only on certain graphics cards, enchanted items would cause the hotbar to become semi-transparent whilst they were the selected item.
• Repairing an enchanted item using another item will remove the enchantment it has.
• On October 1st 2011, Notch tweeted an image of the enchantment screen, with enchantments written in the Standard Galactic Alphabet.^[5] The first enchantment translates onto "Well Played Internets You Are Good", the second translated into "These Names Will Be Random And Confusing", and the third translates to "Each Spell Costs Experience Levels". The Standard Galactic Alphabet or SGA was originally created by Tom Hall for use in the Commander Keen series of computer games.^[6]
• Three of the possible words for enchantments are "the elder scrolls," likely a joke at Bethesda, creator of "The Elder Scrolls" series and whose parent company, Zenimax, was suing Mojang.
• The words "klaatu berata niktu" are a (misspelled) reference to "Klaatu barada nikto", a phrase that originates from the 1951 movie The Day the Earth Stood Still and has been since used as a reference in many other movies, cartoons and games, more popularly in Army of Darkness, Star Wars Episode VI, Teenage Mutant Ninja Turtles(1987) and Duck Tales. Similarly, "Xyzzy" is a magic spell in the game "Colossal Cave Adventure" and has been used in several other games as an Easter Egg or cheat code.
• "Embiggen" is a fictitious word from The Simpsons, from a quote attributed to Springfield's founder, Jebidiah Springfield: "A noble spirit embiggens the smallest man".
• All tools, swords and armor enchanted before 1.9 Prerelease 4 will only have Feather Falling I as their enchantment.
• The Silk Touch enchantment is possible on all levels of enchantment when enchanting a golden pickaxe, although extremely rare on enchantments below level 20.
• Enchanted items still pulsate while you have paused the game.
• It was mentioned that, in a future update, the properties of an enchanted item may give it a random yet unique name or even an exciting look in order to add more of an rpg effect.
• The Protection enchantment converts hunger damage to armor damage.
• In 1.2 Zombies, Zombie Pigmen and Skeletons are able to drop rare items, this includes enchanted weaponry.
• It's not possible to get more than 4 glowstone dust from a glowstone block using the fortune enchantment.
• If a pig, chicken, or cow is killed instantly using a bow with the Flame enchantment, it will drop cooked food. However, if one is killed instantly using a diamond sword with the Fire Aspect enchantment, it will not drop cooked food.
• You can only enchant an item one time, but it is possible to get 2 or more enchantments on an item when first enchanting it.

[edit] Bugs

• In multiplayer, players can only see their own enchantment auras, and not those of other players.
• In multiplayer, items that can not normally be enchanted will not appear as enchanted when they are, however they still work as enchanted.
• In singleplayer and multiplayer, hitting an Enderman with an arrow from a Flame enchanted bow will set the Enderman on fire even though it does not take damage from the arrow itself.
• If you quit after enchanting an item, but before taking it off the enchantment table, you may lose the item.

[edit] Mods from the community

Several people have built mods for making the enchanting system less random and more rewarding at higher enchantment levels. Among these are:

• Enchantment Grid
• Superior Enchanting
• Sensible Enchanting
• Better Enchanting
