In AbilityData.slk can negative values be assigned to all Data fields?

Is it as simple as changing something like a healing ward to a negative value, or changing blizzard to a negative value? I haven't really gotten into that very much, and I'm just wondering if something would crash.

I haven't encountered any data field that gives me a crash with a negative value as yet. From my experiences any data field that isn't supposed to have a negative value is simply ignored and makes whatever effect it's supposed to have nullified. Ie, Blizzard.

So if I wanted to have a healing ward do negative damage, I couldn't just modify it in the SLK to be negative?

As far as I'm aware, negative healing ward works. What I meant above was that any coding that isn't built to accept negative values won't work. The damage per wave data field of Blizzard is one example.

Some values do not like being negative, and tend to crash the game... For instance, negative life regeneration aura (what fountain of life has) will give a fatal exception error and quit the game. It's just a matter of experimenting with values and testing them out.
