We have implemented so called”Collection Tasks” also referred to as “XP Items”

You will find mobs which drop specific items and if you click on info, you will see the level range where you can turn them in as well as the NPC who takes them.

It is NOT a quest, where you have to speak to an NPC in advance.

You can only turn in max. 10 items per level (regardless which ones )

You can only turn in 10 items max per individual task.
