A closely related question: The subclass description for Ascendant mentions that Soul Whip provides more bonus damage during Ascended, but I haven't been able to figure out how much bonus damage. My idea for an Ascendant / Shattered Pillar multiclass was to get to Ascended as quickly as possible to take advantage of the extra melee damage rather than focusing exclusively on spellcasting during that time. Does anyone know how much bonus damage Soul Whip provides during Ascended?
