'''[[Minecraft:Enchanting]]'''
* Enchantment system has been rebalanced.

** Using level 30 enchantments, the player has a lot more luck; almost all items get at least 2 enchantments.
** Various actions now reward the player with [[Minecraft:experience orb]]s, such as mining [[Minecraft:ore]]s (except [[Minecraft:gold ore]] and [[Minecraft:iron ore]]), using [[Minecraft:furnace]]s, and getting [[Minecraft:achievement]]s.

* Switched the 2 [[Minecraft:eyes of ender]] → 1 emerald to 7-10 emeralds → 1 eye of ender.
* Removed the 36- 63 [[Minecraft:rotten flesh]] → 1 emerald trade.

=== General ===
