GUIDEMechanics and How to Use

At a Glance

A Pride Slash E.G.O to give to Blade Lineage Mentor, strengthened by Drink to the Fallen and Poise, that deals high damage from its second use onward.

Core Mechanics

Preferential treatment for Blade Lineage Mentor: For Blade Lineage Mentor, the Wrath, Pride, and Envy requirements each drop by 1 (leaving only 3 Pride), and the damage increase from Drink to the Fallen applies doubled.
Drink to the Fallen: He gains 4 Drink to the Fallen on the turn after use (the first use costs 15 less Sanity). At Turn Start he gains Poise (doubled for Blade Lineage Mentor), his Critical damage grows, and if he takes damage that would bring his HP to 0, he recovers based on the Drink to the Fallen value (once per battle).
Damage from the second use onward: In a battle where he has gained Drink to the Fallen, damage against the main target increases (+60%, 80% at Threadspin Ⅲ, 100% at Ⅳ). Doubled for Blade Lineage Mentor.
Supporting allies: Before attacking, gives 4 Poise Count to the allies earliest in team order, and after attacking, restores 10 SP to the 4 Blade Lineage allies with the lowest SP.
Blade Lineage Mentor-only effects: With Drink to the Fallen, he gains Resentful Scabbard. While using Yield My Flesh, his HP cannot drop below 10, but his Clash Power decreases. With Pride Resonance, Blade Lineage allies receive Sword of the Homeland - The True Essence.

How to Use

In Blade Lineage teams, fire it early to hand out Poise and SP and gain Drink to the Fallen.
Attack with Yield My Flesh and To Claim Their Bones while Drink to the Fallen lasts, and the second use carries the damage increase.
The Corrosion skill gives every ally and enemy 4 Poise, 1 Slash DMG Up, and 1 Slash Fragility. It raises allies' Slash damage, but also increases the damage they take.

A practical guide based on the skill and passive descriptions below.(Updated: 2026-10-18)

ANALYSISThreadspin

Ⅱ: Unlocks Beads of Liquor at Bladepoint, completing its main effects.
Ⅲ: Raises the caps on Poise-based Clash Power and damage, and strengthens the damage increase after Drink to the Fallen.
Ⅳ: The same kind of improvement as Ⅲ, likely a low priority.
