T-elos is a Rare Blade in Xenoblade Chronicles 2. She can grant tremendous power to her Drivers, Rex, Nia, Zeke or Mòrag, and their allies. T-elos uses the Dark element, wields a Greataxe, and acts as an Attacker in battle. She is known as T-elos Re: in the Japanese version. After installing the Patch (Ver.1.4.0) and having cleared the game's main story, T-elos can be awakened from a Core Crystal with a higher probability rate than most Blades.
