Virulent Agent

You coat a weapon or projectile with a concentrated venomic agent. The toxin stays on the weapon or projectile for 2 rounds. Due to the power of the toxin, it can only be used once per weapon before the weapon needs cleaning (next short rest) but it can be used on several weapons per battle.. The toxin only transfers on a successful hit; struck targets suffer immediate bio-damage as cells rupture and organs begin to fail.
