- [Event] Merchant Zyro has returned (Lorencia / Devias / Elbeland)
- [Event] Merchant is Gone
Where to Find Zyro
Every visit, Zyro appears in one of three cities, chosen at random. The announcement does not say which one, so check all three:
Lorencia
131, 138
Devias
226, 52
Elbeland
55, 199
How the Quest Works
- 1Accept the quest from Zyro while he is in town.
- 2Hunt the monster. The quest item drops only while the quest is active — if you haven't accepted it, it will never drop.
- 3Bring the item back to Zyro — again only on Wednesday or Friday between 18:00 and 20:00.
If you are fast, you can accept, farm and turn in a quest within the same 2-hour visit. Otherwise, keep the item and wait for Zyro's next visit.
