Adversity

[Jumpy]

Being unable to use a gimmick doesn't make it bad. The health drawback of Adversity is the exact same that angel wings gave to demiangels and it was a buff considered overpowered. It all comes down to how you use it. Ten seconds is plenty of time to unleash 60md worth of damage. For example you could press adversity and then press sonar cacophony and with that single spell you're literally back to being break even. All it takes is for people to realize you're not meant to spam adversity all fight long; you're meant to weight its cost/reward with how much you believe you can land.

Treat it like invigorate and it'll be better. Combine it with caster or ifrit. Use spells that can't miss. Use an aura that gives AP in order to make that boost even better.

I'd take baiting out a mistform at the cost of 3000 health anytime, even if I didn't get an extra 50 power that would last longer than the mistform.
