Zone Quests & Mastery is a new secondary progression completely seperate 
from the main progression, but also happening completely simultaneously.

In order to unlock zone mastery, you must first complete the very grindy corresponding zone quest.
Once the zone quest is completed, you automatically unlock zone mastery.

The moment zone mastery is unlocked on your character, it adds a new itemgroup to all the inhabitants of the area.
At the start, the itemgroup only adds undead remains (kind of like heads) to the zone.
These remains must be collected and turned in to the Zone Master to increase your Zone Prestige Level.

You will start off at Level Mastery Level 0 when the zone quest is completed.

Prestige Level 0 has no bonusses except for the added itemgroup, that makes monsters leave behind remains.
Once a certain amount of remains are turned into the zone master, you reach zone prestige level 1.
