Changing to Brigid

[hampy]

hello, i'm thinking about changing to the god brigid and intend to get its relics. I understand that I wont be able to use weapons... anyway I was wondering if I would be able to change back after a while? say back to bile, can I do this and would I be able to use weapons again?? or if I change to brigid will I be stuck without weapons forever?

thanks for help
