Collectable

Collectables are items spread all over the worlds of the Xenoblade series.

Xenoblade Chronicles
Collectables lie all over Bionis and Mechonis. Thjey are needed vor various quests, including Colony 6 Reconstruction. Collectables can also be entered in the Collectopaedia.

Xenoblade Chronicles X
Collectables work about the same in Xenoblade Chronicles X. They can be found all over Mira and can be entered in the Collectopedia.

Xenoblade Chronicles 2 and Torna ~ The Golden Country
Collectables in Alrest work a bit different. Collection Points won't simply give you the item when you walk over them, instead you have to inspect it and get multiple collectables. Blades can have skills to yield more or better items.
