Hello all, @Conguero
I am pretty sure that Spirit of golem (30% HP decrease) worked for Burning Mechanic Golem too.
I was hunting at solo areas last days mostly full AFK so i not noticed it before, yesterday i switched to KOO
and saw that when the animation of Spirit Golem activates from the Burning Mechanic Golem no HP is decreased.
so my question is, do i missed a skill change on it or is it a Bug
