Overview

The part-time vending system, using Sales Cert and Purchases Cert, allows you to sell or buy items with any class by “hiring” a Sales/Purchase part-timer. The part-timer you “hire” is a copy of your character, giving you the freedom to still play your character or even go offline after setting up your shop.

You can use a maximum of one Sales Cert and one Purchases Cert at the same time in each account, i.e. You cannot use two Sales Cert at the same time in one account, even if you use two different characters.

You can obtain Sales Cert and Purchases Cert by:

• Doing the quest <link to the section>
• Purchase the Cert from NPC <link to the section>
• Purchase the Cert from other players as it is tradeable

There are three different grades of Certs (Beginner, General, Master), which differs in the maximum number of items you can vend. The 1-Day Cert is usable for 24 hours. You can also exchange three 1-Day Cert into their corresponding grade as 3-Day Cert <link to the section>.

The Quest

Base level requirement = Level 40
To start the quest, speak to Masha (alberta_in 20/19) found inside the Merchant guild in Alberta, and select the level of request to receive and accept. Masha will briefly explain the requirements of the request.

There are three levels of requests, which corresponds to the different grades of 1-Day Cert you will receive as reward.

A character can only accept 1 request per day (either Beginner, General or Master level), with a 7 days cooldown period.

Beginner Level Request

Beginner level request is a simple delivery request. Masha will randomly select one of the five cities listed below, and request you to deliver a Slightly Aged Antique Box to the Sheep working there.

Find and talk to the Sheep which will give you a receipt in exchange.

Return to Masha to hand over the receipt, and choose to receive either a Sales (Beginner) 1-Day Cert or Purchases (Beginner) 1-Day Cert.

General Level Request

For general level request, Masha will request you to retrieve an item from a NPC working on a quest, or hunt monsters.

*Tip: For the initial access to Prontera Culvert via NPC Drainage Soldier (prt_fild05 270,212), you need to speak to NPC Temple Hero (prt_in 88,105) to join the Drainage Fighting Team in North-West Prontera.

For item retrieval requests, Murian or Elbery will pass you a Slightly Aged Antique Box. Return to Masha to hand over the Box, and choose to receive either a Sales(General) 1-Day Cert or Purchases(General) 1-Day Cert.

For hunt requests, talk to the Sheep in Alberta Merchant Guild to obtain the Receipt after you completed the kills. Return to Masha to hand over the Receipt, and choose to receive either a Sales (General) 1-Day Cert or Purchases (General) 1-Day Cert.

Master Level Request

For master level request, Masha will request you to visit biolab 3 to either hunt monsters or obtain data.

For hunt requests, speak to the Sheep in Alberta Merchant Guild to obtain the Receipt after you completed the kills. Return to Masha to hand over the Receipt, and choose to receive either a Sales(Master) 1-Day Cert or Purchases(Master) 1-Day Cert.

For obtain data request, Masha passes you a Data Retrieval Card. Talk to the Sign (Mechanical Equipment) at Biolab 3 to swipe the card to obtain data. Return to Masha with the Data Retrieval Card, and choose to receive either a Sales(Master) 1-Day Cert or Purchases(Master) 1-Day Cert.

Cancel the Quest

If you change your mind on doing the quest (e.g. the request is too difficult for you to complete), you can cancel the quest and re-accept a new quest.

Talk to Masha, and choose “Cancel Request”. You will be chided by Masha before she cancels your quest. Talk to Masha again to accept a new quest.

Purchase the Cert

If you wish to buy (sales or purchases) 1-Day Cert, talk to Masha and choose “Solve this with money”. This option is available before taking on the quest, or while the quest is on cooldown. If you are in the midst of the quest, select the topic “Purchase a cert”.

The price of the 1-Day Cert varies with the grade of the Cert. You can purchase up to 30 Certs in a conversation.

Beginner: 500,000 Zeny/ ea
General: 1,000,000 Zeny/ ea
Master: 2,000,000 Zeny/ ea

Exchange to 3 Day Cert

Talk to Ridwan to exchange three 1-Day Cert for one 3-Day Cert. The Certs must be in envelope form (no trade restrictions); opened Cert cannot be used for exchange.

How to Use the Cert

Sales Cert

Double click on Sales Cert in its envelope form (no trade restriction) in your inventory to obtain the voucher form (trade restriction applies). Double click on the voucher form to open your sales shop.

You must have the items you wish to sell in your inventory, not in your rental cart (take note for merchant class). The possible items that you can sell will appear in the pop-up box “Items available for vending”. 

Drag the item to the shop, set the quantity (in ea) and price, and input a shop name. The item moves from “Items available for vending” to the shop. Click OK to proceed.

You have to pay 5% tax if your selling price is above 10 mil Zeny.  “Price” is how much the item is vended for, while “Selling Price” is how much you will receive from the sale after tax.

If you keep the tick on “Safe check for over 10,000,000 Zeny”, you will get a confirmation message when you vend an item above 10 million Zeny.

Select an empty spot to open your shop, then click OK to the pop-up message.

Your shop is now open with the help of your part-timer. Double click on your shop to see how many items are left in your shop, and the remaining time on the Cert.

To exit your shop (continue keeping your shop open), click “close”. To close your shop (not vending anymore), click “Cancel” and “OK” to the pop-up message.

Your Cert can be used up til the expiration date and time. The amount of time remaining can be checked from the shop, or from the Cert itself.

At the end of the vending period, or when you have sold all items, your part-timer will disappear.

The Zeny earned from items sold during the vending period can be claimed via Rodex.
At the end of the vending period, or when you cancel your shop, all unsold items will be returned via Rodex.

Purchases Cert

*Caution: Not everything can be bought using this method; from experience, some of the items in Item tab and some of the items Etc. tab of inventory is possible, equipment is not possible. You can identify the possible items when you open your shop.

Drag the item to the shop, set the quantity (in ea) and price, and input a shop name. The item moves from “Items available to buy” to the shop. The “purchase Zeny limit” is also updated at the bottom, showing how much Zeny will be taken from you when you open the shop. Click OK to proceed.
