Gladius, also known as Tricephalos or the Beast of Night, is the first major boss in Elden Ring: Nightreign’s Expeditions mode. This formidable three-headed beast challenges players with intense battles, demanding strategic planning, thorough preparation, and quick reflexes. Whether adventuring solo or in a team, understanding Gladius’s location, combat patterns, and vulnerabilities is crucial to navigate this difficult encounter successfully.

Gladius resides deep within the Nightreign’s treacherous terrain. To reach him, players must navigate through perilous landscapes, overcoming various enemies and obstacles. The journey to Gladius is as challenging as the boss fight itself, requiring players to be well-prepared and vigilant.
Understanding Gladius’s Mechanics
Gladius is a unique boss with several distinct phases and mechanics:
Three-Headed Form: Initially, Gladius appears as a massive three-headed beast, combining the ferocity of a Cerberus with devastating melee attacks.
Split Phase: At certain health thresholds, Gladius splits into three separate one-headed wolves. Each wolf exhibits aggressive behavior, often targeting individual players. This phase tests the team’s coordination and ability to manage multiple threats simultaneously.
Reformation: After a period, the wolves merge back into the three-headed form, often unleashing powerful area-of-effect attacks during the transition.
Combat Strategies
Team Coordination
Effective communication and role assignment are crucial:
Tank Role: A player with high defense and health should focus on drawing Gladius’s attention, allowing others to attack safely.
Damage Dealers: Players equipped with high-damage weapons or spells should focus on exploiting Gladius’s vulnerabilities during openings.
Support: A player dedicated to healing and buffing teammates can significantly enhance the team’s survivability.
Weapon and Class Synergy
Certain weapons and classes have proven effective against Gladius:
Bleed Weapons: Weapons that inflict bleed damage can rapidly deplete Gladius’s health, especially during the split phase.
Magic Users: Classes like the Recluse, equipped with spells such as Stars of Ruin, can deal significant damage from a distance.
Guardian Class: Known for its durability, the Guardian can effectively tank Gladius’s attacks, providing cover for teammates.
Exploiting Weaknesses
Understanding and exploiting Gladius’s weaknesses can turn the tide of battle:
Targeting Legs: Attacking Gladius’s legs can disrupt his balance, creating openings for further attacks.
Avoiding Fire Attacks: Gladius’s fire-based attacks are powerful but often telegraphed. Observing his patterns can help in dodging these attacks effectively.
Managing Split Phase: During the split phase, isolating and defeating each wolf individually can prevent them from overwhelming the team.
Solo Play Considerations
While challenging, defeating Gladius solo is achievable with the right approach:
Preparation: Clearing the map and leveling up before the encounter can provide the necessary strength and equipment.
Patience: Solo players must be patient, waiting for the right moments to strike and avoiding unnecessary risks.
Utilizing Terrain: Using the environment to one’s advantage, such as high ground or obstacles, can help in evading attacks.
