Shockwave Totem is a spell skill. It summons a totem that releases shockwaves that deal physical damage around it. The damage done by Shockwave Totem is Spell, AoE, Totem and Physical damage, so modifiers to any of these will increase it. As the damage is Physical, it will not benefit from Elemental Spell Damage nodes. Totem range is 80. Because Shockwave Totem deals physical damage it can be boosted by supports and passive skills that are more commonly used to modify attacks, such as the Added Fire Damage support gem or passive skills which grant Physical Damage with no other qualifier, such as Path of the Warrior.
