How to deal with Darkness?

[Ink]

they probably wouldn't try to cast Darkness during an assassination attempt.

not that I've ever seen that particular scenario, but I have had mages scripted to cast BF spells (like Storm or something) and seen them not cast it during assassination attempts

[vfb]

I've assassinated a PoD who was scripted to cast Darkness. He cast it, for immediate 200 fatigue. So my Disease Demon flew over and chopped up the PoD while he was passed out.

It's probably not Assassination, but the standard trigger on whether the battle is worth spending gems on.

Regular assassins aren't. Disease Demons apparently are.

Absyian slayers are also considered worthwhile as gem targets.
