Omega Planetes: Full Hunt Guide

The Omega hunt is a high-difficulty endgame encounter added in the recent title update, available only after Hunter Rank 100. It's an ancient, mechanical lifeform from another star — in Final Fantasy a symbol of what separates mortals from machines; in Monster Hunter, a menace to the ecosystem that needs to be put down.

This guide covers the normal version from the assignment and optional quests — movesets and counters, community tips, and recommended item and gear loadouts. The tempered Savage version is covered in the Savage Omega guide. First, the basics.

Team Composition & Roles

This fight is tuned for multiplayer with raid-style mechanic synergy, so bringing friends to coordinate roles is strongly recommended:

• A shield user to draw Omega's attention and tank its attacks.
• A support Hunting Horn for buffs and healing.
• One or more DPS (e.g. Hammer) to wound and break legs.

Soloing is possible — fill missing roles with Support Hunters. If you don't have a voice-chat group, Support Hunters are a much better option than rolling the dice in SOS. A good all-round personal loadout is Lance, Hunting Horn, and a DPS like Hammer to cover every role.

Weakness & Targets

Omega is susceptible to Thunder but immune to most status effects, so bring a Thunder weapon with a good elemental boost. His legs have good hitzone values: forelegs take more from blunt, backlegs are weaker to slashing. Continuously wound and break the legs throughout the hunt — consider Partbreaker if you have spare deco slots.

The Enmity System

Enmity is a special aggro system for this hunt. Landing heavy combos and high-motion-value moves on the head draws Omega's attention, shown by a glowing red line connecting Omega to you. This is where the tank matters: the enmity target can bait Omega's position and attacks, opening the fight up for everyone else to recover or deal damage. Crucially, his most dangerous MRV Missiles in the later phase all land on the enmity holder, which makes them far easier to manage.

Phase 1

• Rocket Punch — two fist missiles chase the enmity target. A great damage window since Omega mostly stays put; hide under his legs so the fists hit his own body, or destroy them with attacks.
• Atomic Ray — a multi-laser burst toward one of four cardinal directions that widens with distance. Stand diagonally next to a leg, or block with a shield. He often exposes a weak point on his face right after — focus strike it to create an energy shield that mitigates most projectile, fire, and laser attacks. Stay inside it to deal damage.
• Flamethrower — four-direction fire from under his body; stand beside a leg. A second variant is one large burst directly underneath — outside the legs is still safe. Both can be blocked with Guard Up.
• Ballistic Impact — bombs land on marked circles and detonate after a delay; walk out or block.
• Mustard Bomb — marks one player with a glowing orange icon; a fire bomb drops after a delay leaving a lingering blast zone. Run to the edge of the arena so the fire lands away from the group — or better, sit inside an energy shield to negate it entirely.

Phase 2 & Pantokrator Mode

• Laser Beam — from phase 2 on. He hovers slightly before firing, and it tracks well; run to his side continuously. Thunderpods scattered in the arena shut it down instantly if you shoot his face. He may expose a weak point after — focus strike for another shield.
• Omega-Micros — small adds that explode and interrupt combos; largely ignorable in normal mode (a Hunting Horn echo bubble clears them). Look for the white-glowing one — destroying it creates an energy shield.

From phase 2, Omega enters Pantokrator (enrage) mode — front light red, antenna raised. He's faster, more aggressive, and often repeats moves twice. Focus on wounding the legs and breaking them with focus strike; breaking 3 leg wounds knocks him out of enrage and opens a big damage window, pushing him toward phase 3.

Phase 3

The arena ceiling has boulders — drop them to disrupt Omega's big attacks and save teammates. If you hold enmity here, Omega sends a lightning orb that applies an HP penalty (reduced max health, stacks on repeat hits). It can't be cleared while you have enmity, so stay out of his way or wait for another hunter to take aggro before recovering.

Nerscylla & the Delta Attack — when Omega folds its legs, spins, and flies to the center, it summons a Nerscylla and charges its ultimate, the Delta Attack. The only way to survive is to kill Nerscylla within the time limit — a tight DPS check. Swap to a fire second weapon and ready attack buffs:

• Soul of the Pictomancer's third spell deals huge one-shot damage.
• Lure it into the cactus to trigger their needle attack.
• Malboro creatures nearby can poison/paralyze it — just don't get caught yourself.

Kill it in time and a powerful energy shield drops on the spot — everyone must hide inside before the Delta Attack fires, or it wipes the party. Afterward, Omega sits within reach of the breakable wall on his right — pull it down immediately for good damage and an opening, every single time.

Final Phase

• Larboard / Starboard Wave Cannon — a half-circle laser that explodes after a delay. Larboard = left, Starboard = right; the opposite side of Omega is safe. Otherwise block or run far.
• MRV Missile — the group killer: six missiles in a row targeting everyone. Best answer is to mount up and run. With Evade Window 3 you can dodge them one after another with your weapon drawn (highly recommended). If the tank holds enmity, all six focus him, freeing the group to damage and heal.

From here, keep breaking leg wounds and prioritise survival — Omega repeats his moveset until he dies.

Recommended Builds

Bring an item loadout that keeps defence and damage buffs topped up — this hunt has downtimes, so use every window to re-buff.

Key Terms

Enmity — Omega's aggro system; drawing it (via head damage) makes you bait attacks, including the phase-4 MRV Missiles.

Energy Shield — created by focus-striking exposed weak points (or the glowing Omega-Micro); mitigates projectile, fire, and laser damage. The Nerscylla-kill shield is required to survive the Delta Attack.

Pantokrator Mode — Omega's enrage; break 3 leg wounds to end it.

RULE · Quick Takeaway — Coordinate roles, bring Thunder, and keep energy shields up. Wound and break the legs to shut down enrage, kill Nerscylla in time to survive the Delta Attack, and let the tank soak the MRV Missiles while the group cleans up.
