It simply detects the location where the arrow landed. If its a headshot the plugin multipliers the damage with 2. When its another location than the head the plugin will do nothing. It also detecs headshots on mobs like zombies or pigs.
There is nothing to do but you can change the message which appears when you give somebody/something a headshot. In the config you can set the damage multiplier. Default is 2.
Currently no bugs
