Why is Divine Bolt attached to Divine Barrier and Font of Salvation?

When I press Alt over these two nodes in the Healing Hands tree, the Divine Bolt box pops up. Are these 2 nodes supposed to proc Divine Bolt or is this a bug? If there’s some interaction, how does it work?

Also, when healing is converted to ward with Divine Barrier, will other effects that proc on heal still happen, i.e. Divine Essence and Prayer?

Probably a bug.

If the heal is converted to ward, then no, since you’re not being healed. However, HH does have a heal over time which would proc Divine Essence/Prayer.
