Most Collection Quests begin by examining any of the members of that collection, which are harvested from special, random ground spawning nodes using the Collecting harvesting skill. Members of this collection can be found as follows:
Clickable Objects: Found by interacting with an in-game object, such as a cluster of reeds or a boulder.
Corpse Drops: Found as corpse loot on some or all mobs in the zone, or looted from Chests.
