Abilities with stacking buffs.

[Super-Sheep]

So I made Immolate spell that is based on Shadow Strike but they wont stack. I changed buffs but it didn't help. Any ideas?

they wont stack regardless of what you change in the spell editor, try using channel, or trigger the buff.

I tried adding the target unit into a unit group and then dealing damage to all units in that group matching condition that the picked unit has that buff, but if someone uses shadow strike the buff is gone and it wont take damage anymore. So, I cant find a good way to do this. And what you mean with "Trigger the buff"? :|
