  • When you fight the Putrid Crystalian (Staff), focus more on backstab and attacks that break poise. This will take chunks of its health quickly.
  • Try finishing this fight quickly because if your summon dies all three will start targetting you, thus reducing your chance of victory.
  • After taking out the first one go fight a Putrid Crystalian that is not directly engaged in the fight with your summon. But if you can then try fighting Putrid Crystalian (Spear) next.
  • Similar to the previous fight, try breaking its poise or hitting it with backstab attacks.
