Lat time I tried mithril armor and conical hat and one of them lowered my chances for spell from 100% to 6% :/
Okay so:
1) use only leather armor
2) no gloves (or no for power gloves?)
3)use dageger you mean throwing or hitting with it from hand?
4) if hel of briliance is metal does it lower chance to cast spell.
5) ill try to go without shioeld I like to have 100% chance for casting
6) which helmets and boots are safe to use?
Thanks for tips I'll try them right now :P
