Hardcore Arbiter Paladin Hit a wall at pit 115

I’m currently stuck at Pit 115 with Paragon level 252, 4852 offence/ 1.1m toughness running arbiter wing with sundered night/griswolds opus and I can’t seem to squeeze out more damage. If I remove Endurance of Faith from my arms, I risk dying randomly, this is my 6th hardcore paladin this season. I’m currently stacking around 70 Resolve. Should I consider respeccing into Clash instead?

1st Board - Spirit

Castle - Apostle

Relentless - Resplendence

Divinity - Arbiter

Shield Bearer - Sentinel

I only have two achievements left: kill 1,000 elites in Echoing Hatred and explore Skovos. After that, I’ll probably move on to playing Stellaris or CK3 achievement hunting, especially since there’s less than a month left before the next season starts.

Also, I haven’t killed Lilith or Mephisto yet. I can do around 362B damage permanently — is that enough?
