Welcome <img src="/ubbthreads/images/graemlins/wave.gif" alt="" />
you're not doing anything wrong - but please tell me this: How are your resistances? Those traps are not that deadly - or tell me your level, please.
I fear you've got the resistances bug <img src="/ubbthreads/images/graemlins/think.gif" alt="" /> - are you playing version 1.0034? Cursed item lowering your resistances? Magic barrier skill on an item without an own skill pt first?
