Two bodies, two minds, two souls... one whole.
The Moon and the Sun, dancing ever around each other, their radiance reflecting and magnifying to ever greater heights, bringing light and life in their wake.
Yet they are nothing alone.
The Moon without her Sun to light her way is adrift in the world with no direction and motivation.
The Sun without her Moon to temper her radiance sears at the world around her without end.
Let these two stand together, Sun and Moon, and bring others in to orbit their soothing radiance, that they might be healed of what afflicts their minds and work to protect the lights that protect them in turn.
Levels are not going to pull that off.
The solutions to healing herself are
- Learn a second healing spell. One that heals either to full Health or based on a percentage of maximum.
- Train really hard to make it so that the Target by Level effect can target herself multiple times.
The multiplier is *1.8. In four levels it'll be healing for ~22,748, for 80 + 90 + 100 + 110 = 380 exp, putting it at level twelve - right where
Veil of the Lunar Goddess is at - and at level thirteen it'll heal for ~40,946, for 380 + 120 = 500 exp total from where we are.
Stack it with the training from your second solution for best results, especially as we raise her health even higher; combined with Omni-Caster and a high level weapon and she can plausibly throw obscene amounts of healing out.
