"Recognizing wisdom, strength, and courage suprassing that of the Ancients."
Omega Badge (オメガのくんしょう or オメガの勲章, Omega no Kunshō?, lit. OmegaMedl), also known as Omega Medal, is a recurring item and accessory in the series. It is awarded typically for defeating Omega, a recurring powerful superboss. Awarded as a trophy, it often does not provide any bonuses in gameplay.
Omega Badge (オメガの紋章, Omega no Monshō?) is a loot dropped by Omega Mark XII, likely as a reference to Final Fantasy V. Unlike its Final Fantasy V appearance, however, Omega Badge does serve a purpose: it can be used to create the Bazaar item, Dragon Crest, which provides a Wyrmhero Blade.
Omega Badge is a 5★ accessory which can be obtained by defeating Omega on the Vale of Memories event. In order to unlock the battle against Omega, the player must complete all of the dungeons of the event. It gives +20 ATK and +15 RES to its user.
Omega (capital: Ω, lowercase: ω; Greek Ωμέγα) is the twenty-fourth and last letter of the Greek alphabet. It is synonymous with a set's end or limit.
