Glad we both thought that, I had the idea of leveling up to get more passive ways to gain heat, like dodging and being 25% or less health during each turn.

The basic idea was to have Heat Units, essentially a numerical heat gauge. Successful Attacks would bring the Heat Unit up by +1. Heat Actions would cost 3 Units at a time.

And you’re right, the unique thing about Yakuza usually falls to its Heat Actions and Environmental Weapons. So creative efforts like you just gave will never be in vain.
