Merchant Job Quest

Traveling to the Merchant Guild
Travel to Alberta and enter the Merchant Guild located in the southwest corner (alberta 36,42). Inside, speak with Chief Mahnsoo (Merchant) behind the front desk to apply for the Merchant class.
He will require a 1,000 Zeny fee to begin the quest. If you don’t have the full amount, you may pay 500 Zeny upfront and the remaining 500 Zeny afterward.

Delivery Mission
You’ll then receive a serial number and a delivery destination—make sure you remember them. Your serial number will be randomly selected from the following list:
- 2485741
- 2328137
- 2989396
- 2191737
- 3012685
- 3487372
- 3318702
- 3543625
Your destination will be one of these locations:
- Izlude Dungeon (Bylan Island) – Kafra Employee (106,58)
- Prontera – Southeastern corner, Kafra Employee (248,42)
- Geffen – Mage Guild in the northwest building, speak to the man with glasses (inside: 155,122)
- Morroc – Dyemaker’s house in the northeastern area; he is in the first room to the right after entering (271,269)

Go downstairs to the warehouse and talk to the Merchant Guildsman (alberta_in 28,29). You must provide both your serial number and the correct delivery destination. The supervisor will hand you a parcel even if you enter incorrect information, but the receiving NPC will not accept it, meaning you’ll need to restart the process if you made a mistake.
Deliver the parcel to the proper NPC. If your details were entered correctly in step 3, the NPC will give you a Voucher.
Confirmation of the successful delivery
Return to Alberta, give the Voucher to the warehouse supervisor, then speak with Chief Mahnsoo once more to complete your job change and officially become a Merchant.
