Tips
  • Use left-to-right zigzag running patterns on the water to avoid arrows.
  • Replenish Arrows from dead bodies when available.
  • Use cover behind pillars to shoot Archers.
  • Shoot glowing Medallions to reveal pathways and slow pendulums.
  • On Very Hard Mode, Hydra will have two Kiyatts assisting him. Killing them spawns more.
  • The cavern in the Chamber of Everlasting Sleep is an excellent spot for Essence farming (over 3000 Essence per encounter). Farm up to 99,999 Essence to upgrade and purchase items at Muramasa's Statue in the Suspension Bridge Room. Do not trigger the flooding of the Chamber if you wish to continue farming.
  • Use hard combos and Ultimate Techniques (UTs) against Archers and Zombies in the Great Corridor.
  • If you haven't attempted the ambush in the Archives Room, do so now, as it is forfeited after defeating Alma.
  • On Very Hard Mode, Alma has pink shadow fiends assisting her.
