Why not use the remove trap skill instead of casting a spell? Or simply open it and use a bandage to heal up, the traps are not that damaging.
I know it would take longer if you were not successful, with the remove trap skill. And the spell or just opening would be a lot faster.
Still waiting for when Kane starts coding higher end traps that are immune to spells or use lethal traps. Would make having a remove trap suit useful at least.
Let me see what I can figure out though and I will post it here.
