Jobchange quest (monk) mushroom part

[Dementia]

"Talk to Bashu to choose the Mushroom Collecting Test. He will warp you to the test room. In the test room, make sure you begin by talking to Hyunmoo, tell him you want to start collecting mushrooms now.

In this test, you just have to collect mushrooms. He won't tell you how many you need. When you think have enough, talk to Hyunmoo to see it is enough for him to pass you.

In eAthena servers, it seems that you have to have at least 30 of one kind of mushroom, plus at least one of the other kind of mushroom in order to pass the test.

If you run out of patience, you can tell Hyunmoo you are going to give up and he will warp you out."

That's an instant quote from RMS, I know its not the holy god of everything with private servers.

I'd say, just keep collecting stuff until you're allowed to finish. If the NPC says no, farm them for another 5 minutes and try ask again.
