Minor Demon Translation:
-3m Cost, Some HP/FP Cost
-Grants 15% Damage Reduction, +3 all stats for 4 rounds, counts as a transformation skill
-5 Round Cooldown

Also yeah, in RE: to the OP. God no, my idea -was wild- for a reason. It's just to test the boundaries of how far you'd be able to go with transformations, but if that's too complicated, I'd rather just have that, but you could select between three versions of that. Or perhaps those being a trait that requires Cursed Blood? Sadly it will cost from the ability of certain races like Mechanations and what-not be able to use it.

I'd believe the stat bonuses should be variable between the variations:

Demon Translation (Potential)
- Uses 3M and 20% of maximum FP to forcefully release Minor Demon Translation for 4 rounds. +3 to all stats.

Demon Translation (Wrath)
- When lowered to 50% or less HP, unleashes Minor Demon Translation's proposed bonuses for 4 rounds. +6 to all stats.

Demon Translation (Rebirth)
- Upon being lowered to 0 HP, recovers Character LV * 3 HP and unleashes Minor Demon Translation for 4 rounds. Can only happen once per fight. +9 to all stats.

When those transformations end, you gain Worn Out LV10 for 3 rounds.

Each of those conditions as they are because those balance themselves. Potential makes you invest a lot of resources to activate it, Wrath can only be used when you're lowered under a certain amount, but it's for no momentum nor costs, and rebirth gives you a second wind to try and get back at your enemy.
