"Hack"
Only available with pickaxe in hands, it does high hhp damage (low shp), costing no ip, and damage/weight is based soley on pickaxe q and strength.
But, you lose the pickaxe and it becomes stuck in your victim.
The victim then has a 'thorn in foot' type effect until they remove the pickaxe.
Also, if you butcher an animal that has been killed while the pickaxe is in them, you get the pickaxe at a lower q back.
