Walkthrough for Xenoblade Chronicles: Definitive Edition's Post Mechonis Core chapter. Includes quests, boss fights, and tips for Colony 6 and beyond.

Walkthrough
  1. 1
    Upon returning to Colony 6, you'll witness scenes involving Melia and Fiora. Head to the Main Entrance and then south to trigger another scene.
  2. 2
    The sirens will sound; return to the Colony and head to Junks for more scenes.
  3. 3
    Regain control and prepare for battles against Telethia. The first group is lower level, followed by a rematch with the Sunrey Telethia, and finally a Lv 72 Sani Telethia.
  4. 4
    Strategy for Telethia Battles: Use Melia as the primary attacker, especially with Shulk out of action. Set Mind Blast to counter their Soul Read Arts. Defeat them quickly as they have deadly Arts.
  5. 5
    After the battles, more scenes will play out. You'll regain control in Junks with the objective to head into the Bionis and destroy Zanza's curse.
  6. 6
    The guide will now focus on available content before tackling the final areas.
