Sphinx, Devourer of the Unworthy Boss 3 of 10 · Caverns

How to beat Sphinx

Strategy built from the boss's data: which attacks to dodge, what it is weak to and how to open it up.

• Watch for the red attacks: Combo 4, Combo 3, Boss Posture Break, Vanish cannot be blocked, so dodge them instead of holding block.
• Its posture pool is 350. Break it with heavy and parried hits, then land a critical attack for a fixed 300 damage (15% of its HP).
• Some attacks build up Crystallization on you; back off and let the meter drain before trading hits.
• The nearest Lantern is Ancient Lair, about 368 m from the fight, where you respawn after a death.

Weapons, statuses, Ambers and Transmutations that fit this fight, from Sphinx's resistances and the hits-to-kill maths.

Every attack Sphinx uses, grouped into combos, with damage per hit and whether you can block it.

Used in any phase (9 attacks)

Damage is the base value per hit (bosses always fight at level 1, so no level scaling applies). Move names marked * come from the game's internal tags, because the game never shows attack names.

The combos Sphinx's AI chains together in each phase, hit by hit with damage. Red hits cannot be blocked or parried.

Damage is per hit before the placement level's multiplier. AI cost is the string's stamina_cost in the boss's behaviour data: the boss's own budget, not your Endurance. Move names are built from the game's ability tags (English only).

Sphinx has no damage-type weaknesses or resistances: every weapon deals its full damage.

Weak points

When each phase starts and what changes: the posture pool and the resistances each phase record sets.

HP thresholds are shown only where the phase record holds an absolute health value below the boss's maximum; other phases change on a scripted trigger, so no number is printed. Resistance changes compare the phase record's overrides with the base profile in the Resistances section.
