Omega (Final Fantasy XV)

Omega is an extra boss in the Insomnia Ruins final dungeon in the Royal Edition expansion and the PC version of Final Fantasy XV. It is a warmech associated with the ancient civilization of Solheim, entering the battle arena through a portal identical to the warp platforms in various Solheimian ruins, such as Costlemark Tower and Pitioss Ruins. The Ω-Files the player can discover chronicle the story of Omega's discovery as an ancient magitek weapon. The party calls its appearance from a portal "interdimensional nonsense", and Gentiana describes it thusly: ''Man forges a weapon to fell the gods: "Omega". The weapon knows nothing of compassion—only destruction.''

Omega is homage to the boss's previous appearances in the series, being on the same level as the boss in Final Fantasy V and yielding a trophy item, Omega Badge, when defeated. It being an ancient war machine built to kill gods is also homage to its origins, but also befits the story of Solheim in Final Fantasy XV.

Battle
Omega is the toughest enemy in the game, and its attacks cannot be mitigated by wearing the Magitek Exosuit. It absorbs Light and is weak to Lightning. A special Cross-Chain animation sometimes activates for Omega.

It drops the Rare Metal accessory when defeated, which lets Noctis break the damage limit, but in exchange makes him much more vulnerable.

Strategy
Because Omega absorbs Light damage, it may be better to use the regular Armiger rather than Armiger Unleashed. When using Armiger, the player should target Omega's head to trigger a link-strike.

Omega can be taken down with magic. Quint:Thundaga is good with a Noctis equipped fo magic damage. While waiting for magic to recharge, he can use physical attacks aided by food that makes him deal more critical hits, and the Sword of the Father. Ignis's Enchantment can be used to imbue Noctis's weapons with electricity.
