Ultima the actual spell
An idea to adding Ultima spell to Black Mages in FF14, Square could implement a proc system around the Polyglot and Enochian upkeep.
Xenoglossy would function as the skill that procs Ultima which could work one of two ways.
First method. Xenoglossy has a chance to proc Ultima which in this state would be an instant cast spell like Xenoglossy with a third less potency and is off GCD, a good estimate chance say being 20% to proc Ultima. And Ultima would in turn proc at a 30% rate to recover a Polyglot. This would make the interaction react somewhat back and forth on good rng sort of equivalent to how Dancer's Fan Dance and Fan Dance III combos work. While having to track the investment of good proc rate with balancing Enochian still.
Second Method would be Xenoglossy still has the proc function to mold into Ultima, but Ultima's potency is much higher than Xenoglossy and still has an off GCD component, however a 30-90 second cooldown and the chance to return a polyglot to recast Xenoglossy would be around 10% instead. Making Ultima into a solid huge nuke that can be rarely seen, but rewarding to get the chance of using during a fight.
Both methods could lead to some interesting extra gameplay additions to Black Mage while giving a spell some have been wondering if Black Mage will get.
