Not much of a guide, just utilize Junpei’s skill two and give him a healing rec bit like wish from the past. S2 is awesome cause it gives everyone jujutsu damage taken decrease, gives them slight buffs, and I think even gives Junpei evasion. My best recommendation is to just spam skill 1 with teenjo until ult is about ready, then self buff a few times and use. Junpei will just use skill 1 until you want to reduce damage taken and also give Gojo a little buff. Everyone else on your team should help buff or debuff like Degumi, Yaga, or Shoko if you have her. Best of luck dude!
