Luna Heals allies around her for 300 per second.
Increase Luna's Health by 225-1125.
Increase your maximum Moonlight capacity by 8-40%.
Regenerate 2-10% Moonlight every 1s while within 30 units of Luna.
Heal for 10-50 every time you Heal an ally with Moonlight.
Reduce the Cooldown of Luna's redeploy by 0.1-0.5s after healing with Moonlight.
Luna not being able to cap point hurts, but a 50% buff to life link's healing is huge. That combined with the health buff and people in general not really worrying about the dog anymore means you can position Luna wayyyyy more aggressively and not get punished. With Spirit Arrows the cooldown of redeploy is almost nothing as well.
