Scav on your armor is super important here. Also you can totally Soulsplit here and if you run greater reverance corruption harmony etc it keeps your prayer up so you dont have to use pennance.
The top tier of the corruption/harmony/salvation auras allow you to run leech strength and ss with the amulet of zealots for max xp, and as there are 3 auras you just have to extend/reset one of them every 3 hours
