Loki's Dye

Loki's Dye is a Hardmode dye that can be obtained from Treasure Bags from killing Hardmode bosses in Expert mode, as part of Loki's developer set. It doesn't change the color of the armor, rather it adds a dark gray flames effect, similar to four other dyes which are obtained by trading Strange Plants with the Dye Trader in Hardmode. If you have all Loki's Dye in all 3 dye slots, the effect intensifies.
