As simple as energy should be, I'm confused. Here's what I know:
(Assuming I've been in cat form for > 10 sec) I start with 100 energy.
Energy ticks at 20 per tick, no matter what.
My claw (no mangle yet) costs 40 energy, my FFF costs 0 energy, and my rake costs 35 energy.
So, after using rake, FFF, and 2x claw, how can I have 38 energy?
