Not sure if I should put this here, but testing out Healing Prism while I have the Master Maintenance Oil.
In theory, Healing prism gives you +100 Healing Power per Illusion, and the Oil gives you 6 Concentration for every 100 Healing power.
Summoning an illusion on a mob registers the +100 Healing power Increase, but concentration doesn’t go up, nor does Boon Duration.
Yeah, I want those 18 points of concentration pls.
Unless its not supposed to work that way, in which case, the tooltip should reflect that.
