Ghost Killer

Ghost Killer (Dungeon World Compendium Class) 1.0b

If you survive an encounter with a powerful form of incorporeal undead you may take the following move when you next level up: 

You are a Ghost Killer. You may attack incorporeal creatures as if they had a solid form. You also gain the ability to cast all the clerical rotes.

Once you've taken the moves above the following moves count as class moves for you. In addition to your normal list of moves you may choose from this list when you level up:

Undeath Immunity: You are immune to any “special attacks” or abilities beyond physical simple harm that an undead creature may cause. You can never be changed into or arise after death as such a creature.

Scholar of Unlife: You may turn undead as if you were a cleric.

Ghost Slayer: All attacks against incorporeal undead do double damage.

Graveyard Sight: You can detect invisible creatures and have Infravision.
