There is a cabinet in the deinex's tower in the drow city that is trapped and locked. Alas, Imoen is my thief and she doesn't seem able to disarm the trap... I guess her skills are too low. I have tried drinking potions of Master Thievery but it doesn't help. How do I disarm it????
Thanks for the SPOILER!

Is it an instant kill trap? If not, try casting a lot of protection spells on Imoen or another partymember and have him/her open it.

I can't even get the trap to trigger. Because Imoen has found it I can't even try to open the cabinet. Anyone who trys to bust it open simply fails. HELP!! (what is inside anyway?)
