=== Additions ===

'''[[Minecraft:Effect]]s'''
*Added [[Minecraft:Raid Omen]].
**Instead of triggering a Raid directly, Bad Omen will transform into a Raid Omen variant with a duration of 30 seconds.

'''[[Minecraft:Enchantments]]'''
*The [[Minecraft:mace]] now has three brand new enchantments available for use:
**[[Minecraft:Wind Burst]] generates a burst of wind when successfully striking enemies, launching the wielder in the air.
**[[Minecraft:Density]] makes the already heavy mace even heavier, adding additional heft to its smash attack.
**[[Minecraft:Breach]] allows the mace to bypass a portion of an enemy's armor, striking fear into the hearts of even the most protected enemies.

==== Items ====
'''[[Minecraft:Painting]]s'''
*Added five new paintings by the artist [[Minecraft:Sarah Boeving]]:
