When I created my charactor I cliced the button that let me give traits to my guy. Bandit, Raised by ORcs, etc. I choose the one where I have a +10% tech apptitude. But in return for the + tech I can't wield or wear any magical items. Now I can't wear the amulet to talk to the guy in the pool. Any way around this or do I need to spend 30 or so more hours on another charactor.
are you sure the amulet is magical? It might not be ... Also, try getting another character to wear the amulet. See if that works. If not, go talk to the wizards around Tulla. Somebody is bound to know. There's always a way to get things done in Arcanum.
Plojian's Amulet is neutral. In the patched game this is recognized. Patch, then go to a save before you found the thing. Or, patch & try wearing it again.
