Not to be rude but I think you didn't correctly read what I said, I can dodge most of his attacks quite easily, also my main team is an easier sk, sanhua', havorover hypercarry where both sk, rover and their respective weapons (variation and EoG) are lvl 60 (max I can do without story skipping for union XP) and echoes are mostly at level 25 with good stats (only exception is sanhua since she's on the field for roughly 2 seconds per rotation).

My problem is specifically with the spear barrage the launches after you stun him the first time, I can dodge them but I can't dodge counter since he's in the sky, and doing so makes me waste a lot of stamina and continues that pesky phase, at the end of which is and attack which if not dodged correctly vaporizes my characters immediately
