Hello all! For my map I am trying to create a normal chain-lighting effect that also heals the caster for 25% of his health points (via a Holy Light done through triggers). I read that the trigger should look something like this: Unit - Set life of (Target unit of ability being cast) to ((Life of (Target unit of ability being cast)) + ((Current life of (Target unit of ability being cast)) x 0.25)) But I am having trouble adding the underline part to the trigger. I believe it is most likely done via Variables, but I don't have much knowledge on it despite trying to read on the matter. So far, my trigger for the spell is looking something like this.
