I only became aware that it was doing so much damage today (people never report problems).

There were a number of bugs, but I've fixed up the behavior so that hitting someone with 100ap will injure you for 1.5 hearts and hitting a 0ap person will injure them for 1.5 hearts. The damage scales in between, so basically you want to hit lots of low ap people, and none with high ap.

Before it was scaling between 5 hearts either way, but using the attackers ap for the calculation rather than the victims. It was also not correctly injuring the attacker due to some bracketing issues in the script.

Hope this works a little more fairly. It can be tweaked further if needed (perhaps giving it a bias towards injuring people rather than being a pure 50/50 split).
