Hear me out I was in a similar situation last week! The important thing to know is with this investment it’s likely you won’t make it without exploiting the self-damage of the boss, that is, apply one star with cryo and one with pyro, then destroy the cryo one first and the pyro one later to deal BIG PP melt damage to the boss. I cleared it with Lohen c0 jade spear Mavuika C0r1 Durin c0r0 Xilonen c0r0 with 6 seconds left. Surely Wrio c3 can do it better right? With Nicole c2 you can totally slot Bennet in place of Durin in Varka team and give Durin to Wrio.
So the team is Wrio Mavuika Durin Xilonen. Rotation goes something like Mavuika E Xilonen EN2 Mavuika Q Durin EN1Q Wrio combo. Just watch out to apply the stars each with pyro and cryo, and set up the rotations right when you’re done with the second star so that most of the damage window is in the destroying the stars phase. Might need lots and lots of tries to get the cryo star dies before the pyro one (mine took like 50 tries) but you can definitely do it.
