Slam damage is multiplicative to base damage (e.g., Pressure Point, Arcane Fury).
This mod increases the ground slam damage by +200%, allowing ground slams to deal threefold their usual damage.
Seismic Wave also increases the damage dealt by slam attacks performed via Stance Combos.
Works with Wukong's Primal Fury.
It is currently the only mod capable of increasing the explosion effect damage of the Jat Kusar's heavy attack.

On the initial release that showcased this mod, the mod card along with the update notes had noted that Seismic Wave increased the slam radius of the equipped weapon, misleading players to believe that its purpose was to expand the already impressive slam radius of a weapon (such as the Jat Kittag). The mod card text was eventually fixed to reflect its actual function.
Between Update 18.10 (2016-04-29) and Hotfix 22.6.1 (2017-12-08), there were no enemies that dropped Seismic Wave.
