Speaking of which…
I’m trying to understand how this effect relates to this being an Earth enhancement… It really makes no sense, as this feels like a Whirling Fire effect.
Totemic’s unique connection with Sundering spell should be preserved, especially that this is the only real Earth spell Enhancement Shaman has, and it sets it thematically apart from Stormbringer.
How about this instead?
Whirling Earth: Up to 5 enemies hit by your next Sundering are also affected by Flame Shock.
It provides same AoE Flame Shock application while keeping it under an Earth spell.
