Are 'trick' spells viable?

Poison is still not immediatedly deadly to your run the mill militia like a close-up meet with Flare would be, so my classication stays.

I might have to use SH more, but from what I remember the cloud did 1 point of damage and gave weak poisoning...I'm not saying that is useless.

Sulphur Haze is level 2 Evocation with AoE of 4+. It is very useful against big groups, especially if your units can hold them back without suffering too much. Undead are ideal, of course, being immune to poison.

Of course, the fact that it is Evoc 2 means that better spells replace it very quickly.
