He does indeed cast some form of Heal, although I'm not sure which type it is, or with what talisman/chime. He also casts Emit Force at times.

The page needs an entire strategy section, but I couldn't say much about fighting him, really. I've barely tried to kill any neutral NPCs in Dark Souls III.
