Arthas (Lich King Form) & Heroes Spells

[dimitri231]

Hey guys, I need some spell ideas to my units:

Arthas ( Lich King Form )
Lich

Slayer to kill arthas and lich.

The spell cant be overpowered.
The spell cant be damaging aoe
The spell must fit with the unit
The slayer spell cant be more than 1/12 powered than the arthas, lich ones.
The spell can be / Aura / Self / Instantly / Target /.

+ Rep for the guys who give me the idea.
