Enchantra

She has Legions Might, so you don’t have to save her if she dies. She also has the best resistances, she won’t get possessed and attack you! She will enchant your weapons and heal you, but still help in battle with Holy Focused Bolt, etc. Her Magnanimous Cloak will add Health and Stamina to you if you give her curatives. She can also carry everything you want to give her without being bogged down!
