Stuck on Begining Abyss B2

I'm in B2 after >! Being resurrected again after the entire knight party is killed against Helmut !< And it's giving me the option to >! Fight the 2 warped ones at once !< , I'm currently around Lv22 and my party is MC, Berka, Lanavaille, Bakesh, Alice and Adam. Should I try to grind levels or am I not supposed to try this fight yet???
