On top of that, Maiden's prayer in Ex skill slot, some friends with Phoenix for affliction resistance and he's good to go.
+ He said his only legendary soul was Andromeda, so i assume he didnt unlock Granuaile yet (and her ex skill isnt required if he goes with Belphegor).
Gawain is useless since Dike brings A frame debuff already.
Also why healer from another element only?
Avoid damage dealer for obvious reasons but as long as the kamihime provide interesting ability (heal/buff/debuff) its totally viable.
