Warlock DEvour magic on Enemy target

Name. Warlololock

Spell: Felhunter - Devour Magic

Bug: It dosnt work on enemy targets - i have tested with a friend in duels and it just spams "nothing to Dispell" - also when its Auto-toggled it just cast it on itself all the time.

How it should work: well it should remove a Benificial spell from the target. it dosnt.
