Vibrant Reverie/Youkai Hunter armor

The Youkai Hunter armor is a Pre-Hardmode throwing-class armor set. It is obtainable very early, as it only uses Power Ups to craft, requiring 120 of them total. While the full set is equipped, it reduces the cost of using Power Ups by 50%, and also makes the Youkai Repellent Charm free to use while halving its alt fire cost.

Trivia
This set is based off of Reimu Hakurei, the main protagonist of the Touhou Project series.
