Is it possible to make Disease Cloud affect undead units?

[tomoraider]

I have created a spell that's just a modified Disease Cloud, with a different model and little bit stronger. However, the map I'm working on is undead vs undead, and I didn't even know Disease Cloud doesn't affect undead. I've only noticed it when I was testing the spell. So I was wondering is there a way to have Disease Cloud affect undead?

I managed to make the it work using the Item Immolation ability. It doesnt give units the buff now, it only damages units near the spot where the disease appears, so I made it more powerful since it lasts 10 seconds only.

Thanks for help anyway
