Not really a bug and more of a suggestion, but if you run /kill it does apparently infinite damage and maxes out Tough on living armor by giving it the integer limit of xp. This feels slightly exploity to me and should probably have special handling so you don't have 2,147,483,647/10 experience on your Tough stat just by accidentally running /kill
keepInventory was on at the time if that affects things.

Hey M-W-K, I'm unable to reproduce this. Can you specify what version of you're running, or if its a specific mod-pack?

@M-W-K are you referring to the "Tough Skin" (Physical protection) upgrade?

Please use the issue template. Otherwise we cannot reproduce the issue.

Which Version of Blood Magic is affected?
