Hello I'm making a modpack and want to give the player resistence 5 so he is invulnerable for a short period of time. At the moment this isn't possible, because as statet in your wiki the highest powerlevel is 4.
Is there a chance that you could increase it?

Sure, why not? I honestly have no idea why I set the max to 4 in the first place.

Still awaiting Curse approval, but the newest update raises the maximum power to 10.
