Will there be two Ultimate Art Explosion spells in the Future?

“Only 1 spell per [magic] can be turned into an Ultimate Art.” Does that mean a mage can have one Ultimate Art explosion for each magic, gaining two ultimate Art explosions with two different cooldowns in the future?

well yeah I guess

even if i said yes, its more than possible the cooldown would become universal if its deemed too op by the time you can do that

yeah you can thats the point having multiple magics
