Lol it deals 450 damage per unit owned by player 1 around the caster to nearby enemies. And won't work when imported to other maps as well. Fix the leaks, change the ally unit picking to units allied to owner of triggering unit, and hostiles to enemies of owner of triggering unit. Also might want to fix so that it won't hurt magic immunes and dead units.
Also, noticed that the spell is global. At the moment, what it does is that it kills ur hero but kills everything player 2 owns, providing you have like 6 units owned by player red.
