Sphinx, Devourer of the Unworthy is a creature unlike anything else in this world: something the plague brought into being rather than merely twisted, and a sign that whatever drives the outbreak is reaching for more than people grasp. You fight it in the Caverns, which open in main quest chapter 4, DARK DESCENT, and Ancient Lair is the nearest Lantern to its arena.
Rest at the Ancient Lair Lantern, walk about 10 m in a straight line to the gate in the sand wall beside it and step up to its face. You are moved into an open desert under pyramids and the fight starts at once. A sandstorm comes and goes, darkening the arena so the Sphinx is hard to see beyond a few metres.
Empty its first health bar and a second full bar begins; its golden mask comes off during the fight. Its attacks build up Stasis, and its orb bash, single and multiple waves, locust projectile, homing orb, spike, stomp and vanish cannot be blocked, so dodge them. Watch for purple spiral pillars bursting from the sand around you and a rearing pounce with glowing foreclaws; in the second phase winged insects swarm the sky. Defeating it gives 20,000 Catalysts and unlocks Not a Cat Person. At the death screen, hold R: the Sphinx crumbles to sand and you return to the Abandoned Church, where Louis sends you to James.
