Yeah, I am starting with divinity for all, Hyperamemia boost her hp by 100%, and boost her life steal for bloodsucking embrace. Here is my strategy:
Kuroha: Outer blood first turn, then I spam pluto edge, since she has more initiative than Nosh, I use her for healing when one ally is in a dangerous state.
Nuzuna: I use first campaign in first turn to boost her damage by 20%, then spam kitsune flame blade
Nosh: I use her only for her supporting skill and never use her for damage, so, I start the first turn with Earth shelter when the enemy use physical attack, if not, I start with flower sleep, then I heal every turn, I don't really have to remove any ailments with nosh since I gave almost all required immunities in skill tab.
Maria: I start with crimson moon, then brions's secret art, then noble fang for hyperaemia then I spam bloodsucking embrace.
And of course, I redo outer blood or first campaing when needed.
Yes,the 'a' button allow you to see the description of an item. Still, rabi and co deal too much damage and os me with a critical hit...
