well I dont know if this would be consider a Glitch and I dont know if its been posted before here on the forums
but this glitch its good on my opinion since I dont have to recharge my weapons over and over
they become Unlimited sort of, and its good because then i dont need grand soul gems or black soul gems to make them
i can just make them with petty soul gems and they will still be unlimited
they will be worth less but Unlimited its what matters
I didnt cheat for this to happened since i only play Skyrim on my xbox
but what i think does this glitch is having enchanted my armor to 100% less cost of destruction and restoration spells
that should only give me unlimited use of those two types of magic but ever since i did that
my enchanted weapons have been unlimited.
But even then when i have them both I have to make the weapon first and enchanted, save the game, go back to the dashboard, go back in and load my game back and then the weapons will be unlimited
Hope this helps someone or if has been posted already oh well hahaha
Take it easy!
