[Filter] All right. I have a spell - I have not used it here because I have not needed to, so it may require a little testing beforehand - but it creates an anti-magic sphere. It snuffs out every bit of magic across all of the realms that exist in that circle. No spells, no magic items, nothing summoned. I won't use it if it is going to kill you but if you can handle it for a few minutes to test then it is available.
