The elemental spirit totems are unlockable stat and skill bonuses that will apply to your Titan Fights in Guild Wars, the Dungeon, and Tournament of the Elements.
Each Totem will give that element's titans a stat increase at all times.
Additionally, if you gather 3 or more of the same element Titan, the Totem will give your team an additional Ultimate Ability, that will charge like your Titans ults or Hero ults do.
There are three: one for each element.
Each Totem can be evolved to 6 Stars, and can be leveled up to a Max Level of 120.
