Speaking generally of all the BG and IWD games: Most traps CAN be avoided with care, even if at first it doesn't look like it. It just means moving your party one at a time so they can slide round the edge of it. Even the solid bars across the path can be edged around with care, usually. Just save before you try! The only ones there is any REAL trouble with are the ones just on the other side of the door you just went through... and those are not killers, just stuff like 'web' to hold you down...
Anyway, what are your healers for, lol?
