How to treat negative buff like a positive?

I want to make ability based on negative spell. Is there a way to make for AI as positive, so friendly dispel spells won't dispel them. Or at least make a spell undispellable.

hmmm ya i think i can help...
but it won't work for all types of abilities...

To make a negative buff work as a positive is something i can't do but...
if u use a positive buff (e.g. inner fire) with no bonuses then it will be a positive dummy buff. U can then use triggers to create the effect of the buff.

To make an unremoveable buff u could use doom as a dummy... if you want a damaging spell that is... And remove the summon doom guard bit...

Hope this helps
