Thierry, Vince, Momoe. I always found lockdown to be really annoying to run for Cernunnos, for some reason. If I could switch my party up willy-nilly like you can, I wouldn’t even bother. Level 15 CPR is very helpful as a safety net in case you forget Cross Counter is going up this turn like a dummy, though you might want to give Thierry some head guards if they’re available. More defense from Vince is always appreciated, especially if squishier front-rowers are going to be voted in, and raw power from Momoe will be great. There’s also the fact that, the last time I checked, against an enemy like Cernunnos (100% to Cut, 150% to Volt) Lightning Stab will hit harder than Swallow Strike at equivalent levels, even with Clear Stance’s lesser damage buff, and it’ll be able to hit the Healing Rollers in the back, though granted, she’ll eat the melee range damage penalty there.
