The Attribute Purification Ampoule found its place on my belt, countering the decay-inducing attacks that the monster could unleash. With either the Flame or Electric Blitz Grindstone equipped with my weapon, I felt ready to face the challenges of phase one.

After successfully navigating phase one, the Green Monster grabs a discarded puppet and enters its body, initiating phase two.

Phase Two

Entering phase two, I braced myself for the heightened intensity of the Green Monster’s attacks. Implementing strategic dodges, I carefully avoided the charging attacks and aerial assaults. Never daring to approach from the front, I ensured to keep my attacks brief, conserving stamina for evading and running.

The use of Friendship Wishstone and Flame/Electric Grindstone added an extra layer of tactics to my approach, maximizing my chances of success.

Phase two intensifies the challenge, with the Green Monster becoming faster and deadlier. Follow these steps to conquer the accelerated phase:

Strategies For Phase Two

  1. Charging Attack: The monster performs a charging attack three times, concluding with a Fury Attack. Dodge strategically to avoid all instances.
  2. Aerial Assault: Watch out for the monster’s jumps in the air. It jumps three times, ending with a Fury Attack. Move continuously to make it difficult for the monster to hit you.
  3. Avoid Frontal Attacks: Never approach the monster from the front, as close-range attacks can cause decay and substantial physical damage.
  4. Use Friendship Wishstone: If a specter from phase one survives, utilize the Friendship Wishstone to prolong its presence during phase two.

Maintain Stamina and Use Grindstones
