Okay, I think this will simplify things, at least enough to get moving again.
Milestone 0 health is your power die. So everyone should have 4 or 6 right now.
After that, you'll add your power score each milestone. It'll allow for a difference between brute and fine motor characters without ramping super fast, and unlike the system in play with my alpha group right now, it's only one math problem. I know future milestones have an extra health option, but I'll figure that out later. I think it'll go towards advantage on defense, but I'll keep you posted.
For now! Expect a post as soon as I finish feeding the smol bean. Thanks!
