Doom doesnt work

[Doompenguin]

I have a doom spell in my map that spawns treants when the unit dies.

It worked at first but suddenly it says that the targeted creature is too powerful and only works on summons like skeletons etc. I checked the ability through and gameplay constants to see if i could find anything but havent found anything yet. Any help?

Well yeah, there is also a cap on doom for too powerful creatures.
My guess is that you'll have to create a custom spell which will simulate your doom spell.
Attached with triggers in order to make the treants get spawned.

can you explain then why it worked at first and now it wont even work on lvl 1 neutral creeps :S only weak summons like skeletons can be doomed now :S
