For your dai oni consider:
Shadow brand, charcoal shield, horror helm, jade armour, winged shoes(Do they have enc? If so i would swap for boots of the messenger even if they have summon earthpower), lucky pendant, ring of regeneration.

If you have access to phoenix pyre(thats the name isnt it?) consider some minimal gear (shadow brand, charcoal shield, ring of regeneration) and then load him up with a huge amount of regeneration game.

Finally if your dai oni have protection spells and you dont mind them spending an extra round buffing consider having them cast X skin and give them a robe of shadows.

Good dai oni buffs: summon earthpower, stone/iron skin, invunerability, phoenix pyre, soul vortex.
