You could make your guys have really low HP (like 1 hp) and give the enemies immolation, so when you get near them you take damage and die.

Mybey that but but i whnt them on touch not on area of effect.

Immolations has an AOE like what ... 10? just turn of the Special/Caster Effect of Immolation off and no one´ll see how you did it.
