He is asking me to vend. What is that?

in every land there's a small rectangle. In Arctic Frost, it's right against the Wizards house: there's Luna in her Kumoshouse, two blue onion domes with open doors, and Shining Crane Vending Machine.

You pays your 2 Wizard Tokens, and you take your chances. Each machine has prizes that are special to it, and gives out only certian kinds of prizes. There's a Guide for this on Subetalodge.

Ahh I see. Thanks :)
