Big Hat Logan

Sen's Fortress

Rescue

Requirements: The route behind the breakable wall by the resting serpent soldier is open.

What to do: Open Logan's hanging cage with the Cage Key or Master Key and speak to him.

Result: He moves to Firelink Shrine.

Firelink Shrine

Firelink

Requirements: Logan has been rescued.

What to do: Speak to him to buy sorceries. His Firelink shop requires 15 Intelligence.

Result: His early spell stock is available before his Archives journey.

Consequences and cutoffs: His later Archives shop does not use this Intelligence restriction.

Firelink Shrine

Departure

Requirements: Logan is rescued and you have obtained the Lordvessel.

What to do: His departure conversation can send him to the Archives. If you avoid that conversation, reaching the Archives prison also advances him.

Result: His later stock is obtained at the Archives book room.

Consequences and cutoffs: Buying the early Firelink stock is not a requirement for leaving Firelink.

The Duke's Archives

Archives

Requirements: Logan is in the prison tower cage.

What to do: Use the Archive Tower Giant Cell Key to free him and speak to him.

Result: He moves to the small book room and sells his later sorceries.

Consequences and cutoffs: Defeating Seath early can change this sequence.

The Duke's Archives

Early Seath

Requirements: Seath is defeated before Logan's prison rescue is completed.

What to do: Check the book room for his later merchant state rather than assuming the prison sequence is permanently required.

Result: His later teaching can remain available.

Consequences and cutoffs: Check his actual location after reloading; the standard prison rescue route is the dependable route before Seath dies.

The Duke's Archives

Finale

Requirements: Seath is dead and you have bought all of Logan's spells in the Archives.

What to do: Finish his remaining dialogue and reload. Check Seath's first encounter room for Logan, then revisit his former shop room.

Result: The final encounter provides his hat, crystal catalyst and White Dragon Breath; a separate chest holds his other equipment.

Consequences and cutoffs: Killing him before the final encounter can prevent the equipment chest from appearing.

The Duke's Archives

Murder Cutoff

Requirements: Logan has not completed his final hostile transition.

What to do: Finish the later shop, post-Seath conversations and final encounter if you want his complete equipment sequence.

Result: The final encounter and book-room chest supply different parts of the reward.

Consequences and cutoffs: Killing his friendly form early can lose the later equipment chest.
