I did my necropolis deathless run today, and unlike others, I spent a ton of revives(12-15 solo revs, 5 team revives). So here's my experience for average players.
Team
7* r1 guilly (with 6* r2 gr relic)
7* r2 thanos (with 6* r2 ms marvel relic)
7* r1 king groot (with 6* r3 venom relic)
7* r1 vision (with 6* r2 vision relic)
7* r2 shehulk (with 6* r2 hulk relic)
She hulk was the absolute mvp. Guilly was great as well since she deals her max damage ceiling with no ramp. If I can do this quest again, I'll r3 she hulk and r2 guilly.
Titty - solo with she hulk. With fear and grit, she's made for this fight.
Aarkys - 14 min solo with guilly. She has complete control over the fight. Aarkus also thrown his specials like a good boy.
OS - Thanks took him to 70%, king groot to 45% and guilly did the rest. Guilty is awesome for the fight as she completely shuts her down with neutralize
Air Walker - solo with she hulk. Doesn't matter if he triggers his pink buff, grit ignores the unstoppable effect and her debuffs with despair shut his regen.
Cap Britain - Tried with entire team, but I suck with shifting controls. Ended using vision mainly. I wish his damage was little more, he is just perfect tbh. 2 revives and a team revive here.
Wiccan - 4 min easy solo with she hulk.
Psycho - solo with she hulk.
I did a big mistake taking apoc path instead of guardian one. Please take guardian path if you're reading this. Save your stash
Apoc - I had a good run with she hulk, took him to 70%, then it went downhill. I suck dxing apoc specials. And he dealt a lot of damage on block. Spent 2 team revives and 3 solo revives here. Dgyilly did the heavy lifting.
Tigra - easy solo with she hulk. Punish her sp1 with your heavy occasionally to keep the fear up.
Herc - another nightmare. He loves to light intercept you. His behaviours are unpredictable. 2 team revive and 3 solo revives again. Guilly did the heavy lifting here as well.
Cap sam - king groot took 50% health, rest with shehulk
Capiw - easy solo with she hulk, even before the half enrage timer
Drago - easy solo with she hulk, and ineptitudes healed me to fu health
Nova - it's all bout dexing his specials. Spent a team revive here. Nothing complicated though.
Grandmaster - it's nostalgic to fight him after a year. Spent 4-5 revives. Thanos was the mvp here
Rewards? That's the best part
I duped my most wanted champ. Now I can awaken sentinel with my tech ag.
