Regeneration of SP

[Handsome Jack]

I'm not exactly sure if that's even allowed via the rules. From my recollection, Buff proficiency only helps other folks. And stats can only be improved via spending OM (Items, Permanent Increases), or by utilizing SP (Power-Ups, Fusion). Likewise, I don't think you can work this via a Debuff route. The rules as they currently are just don't really support injuring yourself to fuel abilities. Which is why I'm suggesting a Power which would fill the gap.

Lifeburn, Basic(1000 OM): Allows character to expend HP to utilize SP dependent abilities. Cost is 5 HP per 1 SP required by ability.
Lifeburn, Master(+1500 OM): Cost reduced to 3 HP per 1 SP require by ability.

Or some such.
