TLDR: Floral Ascendance perk does not work (at least proven to not work past the first point)
started with 4 unallocated points and a Lvl 10 spriggan. The spriggan does 45-60 damage per hit with orb… Spent 4 (for a total of 5) points on Floral Ascendance. Spriggan damage stayed at 45-60, minions snapshot afaik, so I resummoned Spriggan, however; the damage stayed within the 45-60 range, even though it gained 48% more spell damage.
I have a 92MB recording of said incident if anyone knows how to upload.
