Welp, I overdid it with the CG quest and now I'm trapped in long stall battle urgh... Even though I killed Santa Nightingale first, it really didn't make much of a difference and the buffs even disappeared after a while. Guess they wanted to make it easier compared to Saber Wars II.
Edit: I managed to find a way to 3-turn the Lancer node, but ffs DW give an NP upgrade to Berserkerlot, I would have an easier time if his NP did more damage.
