Do shaman totems stack?
For the most part, no. Any totem buffs (Stoneskin, Grace of Air, Health Stream totems, etc) or debuff totems (Earthbind) do not stack. However, searing, magma, and fire nova totems “stack” in the way that they are both attacking and doing damage to mobs. As well, while grounding totems don’t stack, two shamans can alternate casting grounding totems to intercept more spells because, after one totem dies grounding a spell, the other shaman can cast one during the first shaman’s cooldown period. Lastly, while identical totems do not stack, having a multi-shaman party means that the shamans can cast different totems of the same element (Strength of Earth and Stoneskin can both be up, for example).
