'''Efficiency''' is an [[enchantment]] that increases the player's [[breaking|mining]] speed.

== Obtaining ==
[[Tool]]s of any material except stone or diamond can receive up to Efficiency V through the [[enchanting table]]<ref>{{bug|MC-275443}}</ref>. Stone and diamond tools can only receive up to level IV through the enchanting table, but can be given Efficiency V by combining 2 items with Efficiency IV in an [[anvil]]. Diamond tools with Efficiency V can also be found in [[end city]] and [[bastion remnant]] chests.

The book itself at a random level can be found in the following structure loot chests: [[desert pyramid]]s, [[stronghold]]s, [[ocean ruins]], [[ancient city|ancient cities]], [[woodland mansion]]s, [[pillager outpost]]s, [[mineshaft]]s, [[monster room]]s, [[jungle pyramid]]s, and from vaults in [[trial chambers]].

== Usage ==
{{main|Breaking#Speed}}
The proper tool for a block must be used in order to receive the speed benefit; the enchantment has no effect if the block is mined with the incorrect tool. See the article above for details on mining speed.
