I've discovered a new, wonderful thing! Druids heal when exposed to sunlight.
No, think about it. Have you ever heard of a Druid dying of skin cancer? Maybe. But not skin cancer from the sun, because if a Druid gets skin cancer from UV rays from the sun, the cancer cells immediately "heal" into normal cells. Druids who don't get enough sun can suffer from all kinds of problems.
What's my source, you ask? Because shut up. That's why.
Anyway... isn't it wonderful? I've noticed that since I started getting sun at least twice a week I've lost about twenty pounds a month, without making any other changes.
So, not only do Druids heal from sunlight, but we also get healthier. This has possibilities.
