I have a musashi np lv 2 and i m undecisive about which CEs i use on her. I am thinking about using first sunrise,joint retical or holy night supper (of course all of them are MLB). what is your opinions guys?
Musashi has a lot of CE options. All of the ones you gave are good. he can also be used with Halloween princess, Limited/Zero over, Golden sumo, victor of the moon, and black grail. Literally anything that provides a damage buff of any kind and/or NP charge. She's really flexible cos she is good at everything related to damage. Crit buffs probably offer the best scaling though, so pesonally I'd recommend either Holy night supper or Joint recital/victor of the moon.
Depends on the team? Generally speaking Golden Sumo is better than First sunrise because Musashi has her own buster up and Merlin is always paired with her, Holy Night Supper even better when you have one or two Merlin. Black Grail for maximum burst. Joint recital when there is Merlin and time to slowly build up NP. I have her at NP2 and with Merlin, she pretty much overkill everything now so starting NP CE is better for now.
