The Tocaxin is a mob under the power of Arksiane within Vethea. Tocaxin will walk around Vethea looking for players to attack. Tocaxin will deal damage to a player if the player is within a 8 block radius. The damage done to a player scales to the distance of the player, and the further away you are, the weaker the attack.
The Tocaxin should not be confused with the Cymesoid, a layer 1 mob that is called "Tocaxin" due to a bug.
