ToME: the Tales of Maj'Eyal

Disperse magic does not seem work properly.
I have checked in the source code, and, according to my understanding, it should remove temps effects and sustained spells, without any resistance or saving.

I had disperse magic at level 4 and after the spell, the target still has his 4 sustained effects.

Seems to remove negative effects just fine >:)

(Couldn't get it to remove an essence of speed on a creature though it had no problem killing my own positive and negative effects, sustained or otherwise).

I have also tried on myself and it does work.
The problem is when trying to remove sustained talents from a target.

I tested it on a spider with multiple sustains it seemed to work

I have tried again. I could remove 'burned' from an npc. Not really useful, but it worked.
But I tried on several npc and I have never been able to remove sustained spells. I am in the high peak, and spell saving maybe an explaination. But I do not understand why.
I do not see any way to resist the spell in the source code, so the level of the npc should not count.
But maybe I am missing something.

Yeah, I don't know. I only tried on an orc pyromancer and couldn't remove essence of speed.
