Spiritual Innervation is a buff that is stacked based on healing in the spirit realm in that fight. My question is would it be more beneficial to us to just self heal as much as possible in the spirit realm to stack the buff? Also, if that's the case, what glyphs would we use for that encounter? Would battle healer be viable or a complete waste of time (assuming we only use seal of insight in the spirit realm and truth up top)? I'm just trying to figure out the best way to comfortably avoid the enrage.
