Hi! thank you :) I built it with the idea of 3d6, but yeah i'm sure you could go up a few a dice if you want the final encounter to be way heftier in HP, but then the modifiers get less and less important as you go up also, so there would be a need for a bit of balancing! But i don't think d20s would work because you'll never come close to having enough rage to lose control of your Vacant Lot
