Arach-no-More is a DLC Merc Mission in Xenoblade Chronicles 2. It can be received in the Kingdom of Tantal automatically after clearing the DLC Quest Merclibay's Mightiest. The time required to complete this mission is 30 minutes, but it can be reduced down to 7 minutes by dispatching Blades with the "Superstrength" and "Expeditionist" Field Skills.
It uniquely awards more Trust Points than other normal Merc Missions. Completing this mission will unlock the DLC Merc Mission Showdown at Chilsain.
