Depends on "You grant" or "This grants":
Not sure what triggers it, but this is the second (now third) time a fight (using Anubis) against mob restarts and the skills are reset to the state as the first fight. As is the remembered selected skill. Possibly the hp, too. Only the gained level persists. I don't press any button, in case this is the mysterious re-fight.
Project Ultimate Damage does inflict damage on its bearer without telling its origin and last in the order vs. first. Also, it seems that healing effects effects don't reduce the damage. It also doesn't affect the Judgment count. Had it in the Anubis Demon fight (lasted 3 rounds after gaining access to Lufillia's Favor) and was forced to drink a healing potion (Life potion (M)) which officially healed me for about 900, but I went from 1 hp to nearly 1500. Must have been the items I have. Also, with this damage you need some way to heal with your party, or give it to the Phoenix members to ensure Death at longer fights. Though the Phoenix skills become progressively unusable for Nana as well. Not sure it is worth the hassle, didn't feel like I need it before.
Also, this Judgment stack is a problem like Blazing for Xia. I was literally unhurt by the demon before dropping its hp down to 50%. Had in the end 4 Judgment. I am in end game mode, with everything done to boost Nana, using possible the most powerful form immune to a number of damage sources and you require that I take damage? This simply doesn't work out.
I have no clue what the Ring of Transformations actually does. I never noticed anything as its source.
