I'm sorry if this is asked a lot, but is there a certain way I'm supposed to be playing during the boss fights? I'm stuck at Noo right now and don't feel like I'm getting any closer to beating her. I know I'm supposed to use Focus, but it doesn't really do anything for me because getting broken by her seduction moves usually right after I use it. Any tips?
Someone already mentioned lowering the difficulty but outside of that there are a few things.
Focus is broken only by her breast moves, so using that AFTER one of those is usually ideal. Otherwise, use the other move instead (Calm Down i think its called)
Make sure you take advantage of your weapon moves if you have a lot of energy, pretty sure you start with something that has a good chance to stun and debuffs defense.
Otherwise, Magic slashes and absorbing after 2-3 will help you stay alive/have energy.
It's been a lil while as I am waiting for the new update, but I think that's about everything. I assume you've already bought any gear you can but if not go check the shops in the human city or the one in the other world if its open.
