I don't think the Lifespark used Power Pool, but maybe it only visually updated after the Lanterngeist's attack so it's more a timing issue than anything else.
EDIT: Lol, so glad I have Restoration as a fallback to survive Arrow Rains and not getting any healing supplies in my first Hard Tower encounter. Now to walk it off from 1 HP to 173! :rofl:
And can't just add and remove Heartbeats, because going from 173 to 178 and back again loses me 1 HP every time.
Maybe Recycling works on out-of-battle potions?

First Hard Tower Lord sighted! Bad Egg! HA! Took me a reread to think about what it means! Woo Shoutouts!
Shoot. I should've prepared Gravity against it. It's got soo much HP!
Well. I almost won. 200+ HP it had left. On loss maybe I should be standing outside the Hard attendant?
Maybe I'll get the Glimmersilk Gown.
