how to defeat fallen Ose

to defeat OSE you just need to increase your defense and use only magic attacks because he will just counter you,

and just ignore the poison you cant escape it anyways

the best demons to use against it is the demon Ictinike and Spriggan with 1 single magic attack on its skill list

also get media heal skill asap, to get media skill combine peallaidh with ippon-datara the result is a demon with media skill, or just level up your femme mermaid until it gets media.
