Gear to boost Galilea's self healing?

Do Healing Power or Healing Recieved items boost the healing from Abyssal Form and Corruption? How about Leechsteal Brooch? Does Corruption count as a skill?

Trying to figure out a good gear set for her. Leaning towards her Legendary and Solar Sustainer, if the healing will do anything, or even if you yourself count as an ally in the eyes of that Legendary.

Right now I’m using Vow of Vengence and Vow of Zealous Fury with a Skill damage on minion kill, -Reload Shard Generator.

Healing power and recieved would both help abysmal form, but not corruption. Corruption does count as a skill, but it’s weak enough where it shouldn’t be a factor
