Disenchant Item

You take away either a resistance infused into armor or a attack type from a weapon. Turn a fire sword into a boring longsword, robbing it of any fire damage, then take that enchantment and use it as a spell against your enemies, like stealing the fire from the sword and casting burning hands. Once enchantment has been robbed then used as an attack spell, the user does not have that spell anymore. 

At Higher Levels. When you cast this spell using a spell slot of 5th level, can steal racial resistances from creatures for 2 turns. Can also be used as a weapon against creatures.
