The Charged Alicorn Ring might be preferable over a Might Ring even though it has lower Holy Protection, it has charges through time instead of hits and can probably outlast the later and it turns into an uncharged Alicorn Ring maintaining some benefits (but not the Holy Protection) when the charges run out instead of breaking. |
