[Kameron8]

The new debug message shows the crit damage scaling properly. I tested again this patch against 3 defense Goblin Shamans, and then a much bulkier arena combatant. The damage increases by a little over 17% each time, but I believe it's working as intended. I made a very stupid assumption about math when I first made this thread, and expected headshot to increase the net damage done by 25% compared to a normal attack. In reality, because the game is just adding +crit damage to a number that isn't 100%, that isn't how it should work. The net damage would be this bonus crit % normalized by your default crit damage. I included logs in case I'm wrong a second time, but I'm fairly certain this was working from the beginning. Sorry about that.
