Centipede Demon

The Centipede Demon is a Nightlord-summoned boss fought during the first Night of Expeditions. It is a three-headed, otherworldly demon imported into the game by the power of the Nightlord; it reuses the name and soundtrack of the Centipede Demon from Dark Souls but features an updated appearance and behaviors unique to this encounter. The fight appears as a special Night boss and is encountered as part of the Nightreign event set of encounters.

Mechanically the Centipede Demon is a multi-phase, aggressive melee caster that mixes physical strikes with elemental assaults. Its first phase deals a combination of standard, pierce, and fire damage; in the second phase it retains those damage types and adds magic damage, increasing the threat of mixed damage types as the fight progresses. The boss cannot be parried, but it is vulnerable to a critical attack once its stance has been broken, making stance damage and guard-shattering techniques important tools for opening windows of high damage.

• Do not attempt to parry: the Centipede Demon cannot be parried and will not be stunnable by parry frames.
• Stance breaking is rewarded: after a successful stance break the boss is exposed to a confirmed critical attack; builds that emphasize posture damage or repeated heavy guard damage should capitalize on these windows.
• Expect mixed damage: the fight shifts from physical + fire in phase one to physical + fire + magic in phase two. Equipment and consumables that shore up both fire and magic resistance will reduce incoming damage.
• Positioning and spacing matter: the demon uses sweeping multi-hit attacks and close-range lunges. Maintain spacing to punish recovery frames and to avoid multi-hit combos.
• Team considerations: in group play, coordinate to fracture stance safely and to chain-critical the opening; the encounter is designed to be tackled in multiplayer during Expeditions.

There are no confirmed public statistics for the Centipede Demon’s HP, defense, stance values, or exact resistances in available sources. Likewise, specific drop tables for this boss are not detailed in the cited material. A separate note from Nightreign encounters indicates that if a small group of Imps accompanied by an Erdtree Burial Watchdog spawn beforehand, the impending Night boss will be the Smelter Demon rather than the Centipede Demon; this spawn pattern can be used to anticipate which boss will appear on a given Night.

Lore-wise, the Centipede Demon is presented as a ferocious invader from another realm brought into the Lands Between by the Nightlord’s ritual power. Its direct ties to earlier FromSoftware lore are primarily nominal and musical; beyond sharing a title and soundtrack with the Dark Souls Centipede Demon, this Nightreign incarnation is an evolved, distinct threat tailored to the Expedition Night encounter.
