I'm soloing BG2 for the first time as a mage, and have already cleared the Guarded Compound. Thus far, I've been dealing with traps via Magic Resistance, Spell Immunity, Stoneskin, Mirror Image et cetera. There is however this one chest on the second floor, in the room with four chests by their respective beds, that seems to be an instant death trap. I've tried everything I could think of (Spell Immunity: Alteration didn't work) and there is no Saving Throw for it. The trap goes off, then the squares form up around my mage and he dies.
Is there a way around this? I really want that Wand of Paralyzation.
UPDATE: It's a Maze trap. You'll need Spell Immunity: Conjuration or else it's Game Over if you're solo.
