What fun can be had with temp HP?

[CyberThread]

are their abilities or such that could benefit, from a pool of temp hp to drain, instead of using or sacrificing ones real HP?

[Zanos]

Overchannel, Reserves of Strength, and the Crusaders Steely Resolve come to mind.

I was always partial to the "get hit in the head by a mass of pernicious fellows" method of draining my excess temp HP.
