ok i know how to do the spell trigger but i do not know how to make units where the movelocation die... i do not want the spell caster to die but i want its enemies to die... but if i do that the spell unit will die also can anybody please help me?
you have to specify what you kill then, like
Action -- Kill All (Unit Name Ex.) Zerglings at location X
that is the only way to kill everything but the spell, that i know of
If I understand you correctly, you want a spellcaster to cast a spell that will kill all enemy units at a location centred at the spellcaster?
Couldn't you use:
Kill all any unit for "Enemy Player" at "location".
?
