Ultimalius Boss Guide in Final Fantasy 16

Master the Ultimalius boss fight in Final Fantasy XVI with our comprehensive guide. Learn strategies for all three phases, including Eikonic attacks and how to counter them.

Ultimalius is the final boss in a sequence and features three distinct phases, each centered around different Eikons. He mimics their attacks and introduces new, themed moves. Your potion count carries over from the previous fight.

Stats / Weaknesses:

• Phase 1 Eikons: Ramuh, Garuda, Titan
• Phase 2 Eikons: Bahamut, Shiva, Odin
• Phase 3 Eikons: Phoenix

Phases:

1. Phase 1: Ramuh, Garuda, Titan

   • Fulmen and Fulgur (Ramuh): Ultimalius creates large, exploding electrical circles on the ground. Dodge the circles while avoiding his other attacks.
   • Euroclydon (Garuda): Summons tracking talons that stomp the ground, followed by a larger claw. Dodge the initial talons and then the final large claw.
   • Divine Embrace (Garuda): A fast claw attack that pulls you close to Ultimalius without dealing damage. Difficult to dodge, and he immediately follows with another attack.
   • Cataclysm (Titan): Ultimalius slams a giant arm into the ground, causing exploding rocks to erupt from marked circles. Dodge the circles and the subsequent rock explosions, being careful not to get hit and flung into further circles.

2. Phase 2: Bahamut, Shiva, Odin

   • Exaflare (Bahamut): Ultimalius sweeps a laser across the screen twice, leaving behind circles that explode after a delay. Dodge the lasers and the ground explosions.
   • Boreal Rhapsody (Shiva): Giant ice chunks fall from the sky, with landing spots marked. Keep moving and watch for markers to dodge.
   • Severance (Odin): Similar to Barnabas' Lord's Measure, lines appear on screen and explode with dark energy shortly after. Find a safe spot between the lines quickly.

3. Phase 3: Phoenix

   • Empyrosis: Ultimalius starts with a fire explosion around him, then jumps and crashes into the ground, sending a shockwave across the ground.
   • Ashes to Ashes: Fires projectiles, then divebombs, erupting in a fire pillar. Dodge the projectiles and time the evade for the divebomb.
   • Flames of Creation: Teleports, creates a giant fireball, and throws it. It explodes on impact, leaving pillars of fire. Dodge the initial fireball if necessary, then avoid the ground effects.

Strategy:

• The fight cycles through Eikonic attacks. Adapt your strategy based on the Eikon currently being mimicked.
• Phase 1 focuses on Garuda, Titan, and Ramuh. Be prepared for area denial with electrical circles and ground slams, evasive talons, and a close-range pull.
• Phase 2 introduces Bahamut, Shiva, and Odin, bringing sweeping lasers, falling ice, and quick-exploding lines.
• Phase 3 is themed around the Phoenix, with fire-based attacks including explosions, divebombs, and large fireballs.
• Maintain awareness of your surroundings and prioritize dodging, especially when Ultimalius chains attacks.
