Yeah that's true about the accessory that Necro mentioned. It does boost your magick defense or something or other to like 18, but it depletes your total MP to 0 and you can't regain it. I don't think it's of much use if you equip it, so just keep a hold of it in your inventory for now aqnd equip something like the Orchalaan (spelling?) accessory that Tomaj gives you. You can buy more of them from traveling merchants and they boost your HP a bit.
