@Sofa_King_Cold Yup. Healing powers are usually saints, clerics, priests, certain magic users, and paladin types. All but the paladin tend to be squishy in other ways, and paladins often have to be high level to do a really good heal. It's very rare for a high-level healer to equal a high-level hero/demonkin/etc. like the goddess cited. 

It's also rare for demons to have healing abilities period. Aside from the occasional dark elf being misclassed as a demon, the only one I can think of is the demon king from "I am the Strongest Boss". (Recommended. If the demon king didn't want to wipe out humanity, the audience would be cheering him all the way.)
