Purely a PvE ring. Weak on it's own, but good when combined with the other HP restore/regen items, such as:
- Arstor's Spear (on your back)
- Aldrich's Ruby (for backstabs)
- Sun Princess' Ring
- A blessed shield +9
There's more but this is my build, and I never chug estus, even in NG+. And they said this game was supposed to be tough.
