Chapter 3 of Ghost of Tsushima Legends presents one of the most intricately designed and challenging boss fights in the game. The battle against EO demands precise coordination, tactical positioning, and an understanding of unique mechanics. This guide will break down each phase of the fight, including tips on managing corruption stacks, countering EO’s abilities, and achieving the coveted under-5 corruption stacks achievement.

Phase 1: Securing the Wells and Managing EO’s Attacks

At the start, three of your team members will need to secure two control points—Wells—while keeping an eye on EO’s attacks. These Wells function similarly to those in Chapter 2, requiring you to prevent enemies from being absorbed.

Key Strategies:

• Assign two players to guard the Wells, focusing on eliminating enemies quickly.
• Designate one player to target EO’s attacks using the Ghost Bow. When EO charges her blood beam attack, look for glowing circles around her head and shoot them to interrupt.

If successful, this not only prevents EO from advancing her attack but also reduces her stagger meter, making subsequent phases more manageable.

Phase 2: The Duel in EO’s Realm

The fourth player must engage EO in a one-on-one duel within her realm. Unlike typical fights, your resolve abilities are disabled here, leaving only your sword skills.

Tips for Winning the Duel:

• Use aerial strikes and water stance combos to quickly stagger EO.
• Watch for the blue glint on her sword—it signals a thrust attack that can be sidestepped for a counter.
• Manage corruption stacks carefully. Reaching 10 stacks wipes the entire team.

If the duel drags on, teammates can shoot the Torii gate to extract the duelist, preventing additional corruption stacks.

Phase 3: Communication and Circle Targeting

EO occasionally spawns multiple glowing circles around her head. The duelist inside EO’s realm can see which circle is the correct target and must call it out to the team.

How to Handle Circle Targets:

• The correct circle appears in the realm a few seconds before the main arena.
• Successfully shooting the right circle halves EO’s stagger bar, making it easier to manage her attacks.

Effective communication at this stage is vital to prevent unnecessary damage and corruption stack buildup.

Phase 4: Rotating Duelists for the Achievement

To unlock the achievement for staying under 5 corruption stacks, you’ll need to rotate duelists.

How to Rotate Safely:

• Swap roles at around 5 corruption stacks. Have a fresh teammate take the next duel.
• Coordinate well in advance to ensure smooth transitions.

This rotation strategy not only preserves corruption levels but also keeps fresh combatants available for later phases.

The Final Phase: EO’s True Form

In her final form, EO emerges with a full health bar, summoning waves of enemies to complicate the fight.

Tips for the Final Phase:

• Have Samurai and Assassin players save their ultimates for this phase to quickly reduce EO’s health.
• Use Hunter’s ranged attacks to manage enemy waves and apply consistent damage to EO.

Focus on burning down EO quickly before the overwhelming number of enemies becomes too much to handle.
