I've been looking for advice on an enhancements for a healing-focused pure Cleric (human) but can't seem to find any. I see lots of advice on Cleric/Monks and Battle Clerics but not much on healing clerics.

Unlike my main character, a pure rogue, I'm running out of enhancements to pick. (my rogue has the opposite problem; too many good enhancements, not enough points)

The chains I'm taking so far are:

Cleric Life Magic
Cleric Energy of the Zealot
Cleric Wisdom
Cleric Divine Vitality
Cleric Spell of Life (healing crit?)

When I take Toughenss, I'll start on the Toughness chain but what else should I look at?

Extra turning for more DVs?
Improved Empowered Healing for lower SP cost?

Others?
