Spirit Bond

Usage
Maybe not intended by the dev, but this skill still activates with Protective Spirit. Lets say you precast prot spirit and this, you get hit with an Obsidian Flame, though you only take about 40 damage, Spirit Bond will activate and you will be healed.

This skill is very useful in high-hp Monk farming builds, as there is theoretically no upper limit to the number of enemies you can tank at once. While vulnerable to enchant stripping and a lack of heavy-hitting enemies, Spirit Bond farmers are significantly more resistant to health degeneration then low-hp invincimonk farmers are. Consider including Retribution to add some extra damage.
