While it’s possible that this is just a description ambiguity (if it’s a description issue hopefully the description will be changed to be more clear), I think it’s more like a bug
Regarding the spell Lightning Storm from the Fury Of The Elements node of EQ, based on the damage data of 40 hits against enemy-type dummies:
- Lightning Storm will be affected by Concussion/Rupture node’s more bonus, but not affected by Crushing Wake, unless get the Seismic Smash node so that the aftershock bonus is given to the initial hit (i.e., consistent with EQ’s initial hit, not consistent with aftershock)
- Lightning Storm is not affected by Shatterquake node bonus, I think this is not normal
