This skill allows you to apply poison from a potion bottle onto your weapon 
of choice to add some damage and nasty effects to your melee attacks. Poisoned
weapons are especially deadly against other players and an assassination
attempt with a poisoned weapon is among the most deadliest ways to begin a
combat (though usually the target dies from the poison enhanced assassination).
