Corruption resistance and health stacking will help if you get hit by poison, if you need your stam curio, go for it. If you are not rocking maxxed corruption resistance, it is also fine. You won't need survivalist for this fight unless you want to do pepega horde gunning.Strat: 1x Ogryn, 1x Vet, 2x FlexVet runs Field Improvisation - drop ammo box for Ogryn only. Ogryn has 5x Ogrynheimers for the fight. Use Ogrynheimers as an i-win button when there's any unfavourable spawn timings during the fight. Smite Psyker is unoptimal for this fight, everyone should be contributing to elite sniping and boss dps.
