Design: Tubikh Rrahim [2, 6!+1, 2]
Magic is tied to the divine. This much is obvious from the very nature of the magic; miracles wrought on earth through Allah's blessing, used by the righteous to strike down the wicked. The Arstotzkans have perverted this gift from God, and it is our duty to stop it.
Tubikh Rrahim is our solution.
Imams carefully select the most pious of our mages for this process and prepare them for the spell. Since piety isn't restricted by experience, it's not uncommon for apprentices to be selected. It is a great honor and ceremony for those blessed with Allah's will. After a period of solitude, prayer, and reflection, these individuals are ready to cast.
The spell is every bit as absolute as we could have hoped. Magic fizzles in the area so long as the mage holds the spell, which they can do for up to a day at a time. It is the absolute iron fist of Allah, binding all magic in his merciful hand.
Unfortunately, this means our own mages are unable to cast as well. The spell requires an hour of preparation before casting, and doesn't dispell existing enchantments. Even worse, the spell consumes those who cast it - though they are physically unaffected, they can never use magic again. Still, this is a powerful weapon that clearly demonstrates that the will of Allah is with us. [Against all odds, Normal Cost.]
