Short Answer

Mother of Stones is less a duel and more a controlled add fight. The boss itself is immobile in a Fright Cliff - Squall Hideout cave, but it summons lesser yaoguais that can overwhelm you if ignored. Clear the adds before they pile up, damage the crystal boss between waves, and keep the key item for the Man-in-Stone quest chain.

When This Guide Helps

Use this guide if you reached Squall Hideout and expected a normal boss, or if you keep losing because enemies stack up while you focus the health bar. The safest plan is not to race the crystal. It is to control the room.

This encounter matters because it feeds directly into the Man-in-Stone side path, which unlocks more Chapter 2 value after you finish the follow-up.

Route And Unlock Context

From the Squall Hideout shrine in Fright Cliff, take the route into the cave with fire pits and follow it to the glowing crystals. Attacking the crystals starts the Mother of Stones encounter.

After defeating the boss, take the key item back into the Man-in-Stone quest path. Treat the reward as side-quest progress first: it is the item Man-in-Stone needs before that route can continue.

Core Mechanics

Mother of Stones does not fight like a mobile boss. It stays in place and relies on summoned enemies. If you tunnel the boss, the summoned enemies can surround you, interrupt healing, and turn a simple encounter into a failed attempt.

The rhythm is clear adds, hit the boss, clear adds again. If you have A Pluck of Many later, it can help distract or clean up enemies, but the fight can be handled with basic target discipline.

Moves To Respect

Respect enemy buildup. One lesser yaoguai is manageable; several at once can body-block your dodge and heal.

Respect the cave walls. Do not fight adds with your back trapped against the arena edge.

Respect the quest item. Leaving without using it on the Man-in-Stone path means the fight’s main route value is unfinished.

Fight Plan

  1. Follow the Squall Hideout cave route to the glowing crystals.
  2. Start the fight only when you have room and health.
  3. Kill summoned enemies before they become a crowd.
  4. Damage Mother of Stones between add waves.
  5. Take the reward into the Man-in-Stone quest path before forgetting the side route.

Use quick area control if you have it, but do not overcomplicate the fight. Immobilize is better saved for adds that interrupt you than for the immobile boss. A reliable Spirit can also clear a cluster if enemies group tightly.

Common Mistakes

  • Focusing the boss while adds surround you.
  • Healing in the middle of active enemies.
  • Backing into the cave wall and losing dodge space.
  • Forgetting that the reward belongs to the Man-in-Stone route.

Quality Check Before You Move On

You are ready to move on when the cave is clear, Mother of Stones is defeated, and the Man-in-Stone quest item has been taken to its next step.
