Maya's First Collection

Before

Go see Maya in Henesys.

In progress

I got a request from Maya of Henesys, who likes collecting all kinds of items. She wants 20 of each of the following: Orange Mushroom Cap, Green Mushroom Cap, Blue Mushroom Cap, and Horny Mushroom Cap. It looks like I can get all of these from hunting monsters around the prairie...

Completed

I got everything Maya asked for, but when do I get rewarded for this? What? How many more times do I have to do this??
