Maybe grab a vicious weapon. You'll be packing so much self-healing that you might just want to inflict damage to yourself to keep your damage pool going.
On a Wrathful Healing weapon with Thereputic Mantle, you actually just
increased your healing. Deal 2d6 more damage to your foe and 1d6 to yourself, being healed for half the damage you dealt +(2*essentia).
That's scary. You can heal yourself by taking more damage.
