Battle Pet Totems are items found in-game that can be added to the players' Battle Pet to increase it's usefulness in PVM.
For most totems, players can add up to a maximum of 2 totems for double the benefit! This does not work with all of the totems. For example: adding 2 Totem of Ranged (Level 4) to a battle pet grants the player a total of 30% ranged bonus.
