A desperation attack is something that is high-risk, high-reward. So, I imagine that scaling up the FP cost, removing the cap on damage, twinking the math of the skill so that tanks don't do more damage with it, and making it only usable once per fight or with a large cooldown would make it fit its' description.

The thought pattern that you put in the idea 'desperation attack' is quite well-portrayed in what you say.

I'll have to agree there.

Kind regards,
