The king cobra is the longest of the venomous land snakes, capable of staring a human in the eye when standing upright. Its bite injects a powerful venom in sufficient quantities to kill a full-grown elephant.
When placed on your forehead, this tattoo gives you a 5% chance per rank of injecting your victim with venom whenever your bite attack achieves a critical success, as well as +1 poison bypass per rank for your bite attack.
When placed on your chest, this tattoo provides you with +2% natural armour on all locations vs poison damage per rank. If you also have Swamp Wolfkin, your first 10 ranks in this power will each give +1% poison immunity.
When placed on a forearm, this tattoo gives you +1 poison bypass per rank to all attacks made with that hand (both with and without weapons).
When placed on your shins, this tattoo allows you to bite while prone.
