Healing Hands has a node that gives you a +25% chance per point (capping at 100%) to cast healing hands when you hit with a melee attack. Healing Hands also has a node that converts it into a melee attack. I don’t know why I never considered Healing Hands proccing Healing Hands, but now I shoot 16 Divine Bolts per swing (10+3 from HH1, 10+3 from HH2 ) and it’s glorious.
Edit: on a side note. I’m trying to decide between Symbols of Hope for Divine Flare or Abyssal Echoes (converted to Fire) for an AoE button. On one hand Divine Flare does insane damage in a relatively large area and gives a decent enough buff (+12 Fire Melee damage and +12 Fire Spell damage with my spec) between casts, but Abyssal Echoes would give me a permanent 20% attack speed boost and deal some AoE damage on top (more the larger the group). Is Abyssal Echoes even worth considering?
