Your wrong michael, you can use soul gems to recharge enchanted items. just "equip" a filled soul gem and a screen with appear and will show you which items can be recharged. then click the one you want to recharge.
Of course your going to need a spell or scroll of soul catcher or something like that (mystisim). and a empty soul gem. one thing to remember is that your soul gem must be strong enough to contain a soul. heres a break down of the soul gems.
Petty- low level creatures like rats
common- still low level creatures, like skeletons and such.
greater- mid range creatures like... boars... and skeleton guardians... goblin shamen?
Grand soul gems- high level creatures, i think it can capture anything.
HEY mucks, have you tried a defragging? I heard this can clean up the game if it starts to behave badly. Try it First!!
