Proto-Omega Boss (The Stigma Dreamscape)

Learn how to defeat Proto-Omega in The Stigma Dreamscape in Final Fantasy XIV: Endwalker. This guide covers mechanics like Side Cannons, Chemical Missile, and Electric Slide.

Stats / Weaknesses:

• Proto-Omega is the boss of The Stigma Dreamscape dungeon in Final Fantasy XIV: Endwalker.
• No specific elemental weaknesses are mentioned.
• Positioning is key to avoiding most mechanics.

Phases:

1. Opening: Proto-Omega begins with Side Cannons, a cleave on the side indicated by arrows. Move to the opposite side. The arena edges will become electrified.
2. Mid-Fight: Forward/Rear Interceptors cleave either the front or back. Move through the boss to the safe side. Three players are targeted with Chemical Missile AoEs; drop these in corners. Immediately after, Electric Slide targets a player with a stack marker and knockback; stack in the center and use Arm's Length or Surecast to negate knockback if needed.
3. Guided Missile: Two players are tethered to missiles that explode, leaving lava AoEs. Kite these missiles away from the party and the boss.
4. Tankbuster: Mustard Bomb deals heavy damage to the Tank. Use defensive cooldowns.
5. Combined Mechanics: Later in the fight, Proto-Omega may use Guided and Chemical Missiles simultaneously, requiring careful placement of AoEs.

Strategy:

• Tanking: Keep Proto-Omega at the back of the room, facing away from the party. This simplifies avoiding Side Cannons and Forward/Rear Interceptors.
• DPS/Healers: Stay close to the boss to make avoiding AoEs easier. Spread Chemical Missiles to the corners. Stack in the center for Electric Slide, using knockback mitigation if necessary. Kite Guided Missiles away from the group.
• General: Be aware of the electrified arena edges after the initial Side Cannons. Avoid standing in lava circles left by Chemical Missiles and Guided Missiles.

How to Tank:

• Always position Proto-Omega at the back of the room, facing away from the party.
• Be prepared to use defensive cooldowns for the Tankbuster, Mustard Bomb.
• Avoid hitting players with the Guided Missile tether.
• Drop your Chemical Missile AoE in a corner.

How to Heal:

• The main damage outside of the Tankbuster is from Chemical Missile, which deals minor group damage.
• Focus on avoiding Proto-Omega's positional attacks, as failing to do so can be fatal.
• Be ready to heal the Tank through Mustard Bomb.

• Defeating Proto-Omega allows progression through The Stigma Dreamscape dungeon.
• Standard dungeon loot drops.
