How to Beat Gladius, the Tricephalos Nightlord
Prepare for the Gladius fight with Holy damage, team coordination and safe reactions to the split-dog phase.
How to Beat Gladius, the Tricephalos Nightlord
In Elden Ring Nightreign, Tricephalos is the expedition name and Gladius, Beast of Night is the three-headed Nightlord you face at its climax. That naming difference explains many confusing search results. The boss is vulnerable to Holy damage and can divide into three hounds, making team coordination just as important as raw damage.
Prepare during the expedition
Prioritize a reliable Holy damage option if your route and loot permit one, but never sacrifice basic survivability for a weapon you cannot use effectively. The Nightreign expedition format rewards gathering upgrades and healing capacity before the finale. Communicate who can handle a close-range target and who needs room to deal damage safely.
Single body: watch the chained weapon and lunges
Gladius can spring forward and use sweeping sword attacks with substantial reach. Keep the boss in view, avoid committing to long attack strings while it is repositioning, and use its recovery windows for short bursts. Its Fire-based attacks add pressure; bringing a Fire-heavy strategy as your only plan works against the matchup's strengths.
Split phase: prevent three isolated duels from going wrong
When Gladius separates, individual hounds can force teammates apart. Call out targets and regroup deliberately rather than chasing a low-health wolf across the arena. One player drawing attention can give ranged teammates time to act, but anyone may need to help a downed ally. The priority is maintaining sightlines and avoiding simultaneous attacks from different angles.
One-player versus co-op adjustments
Solo attempts require especially careful target selection and short punishes. A trio can stagger responsibilities, but it also needs communication about revives and target changes. If an Everdark variant is active, confirm its specific changes before treating a base encounter guide as complete. Do not reuse a damage chart without checking the relevant update.
A team callout that actually helps
Agree on short phrases before the fight: “Holy ready,” “wolf on me,” “need revive,” and “regroup center.” They are more useful than three people shouting damage numbers. When Gladius splits, decide whether someone can safely draw one hound away while another player revives a teammate. Watch how your choice changes the spacing; a scattered team can lose even with a good elemental matchup.
