ToME: the Tales of Maj'Eyal

So... what do I do about layers of visual effects (vomit, creeping darkness, and savage hunter, plus that acid spray are the big offenders) that pile up and make it impossible to see?

I just died (first death) with a Cursed that was effectively indestructible to that point because the creeping darkness and savage hunter made it impossible to see (also, I was cavalier at safety but that's another matter).

Is there some way to minimize them?

Well, I can't attest to the creeping darkness bit, but the acid sprays sound like the sort of thing I wrote Effects Under Actors for.
