Edited by Deathon6: 11/4/2020 1:39:20 AMI just noticed something. It’s still a legendary. The blue is because it’s an arc piece of armor. However the ability to infuse other armor is not available. I edited the main post to reflect this.
I’ve read in other forum topics that the FOTL masks get put down to zero at the end of the festival, and I assume they will be made viable again during the next FOTL. Maybe it’s to avoid their use in-game 🤷🏻♂️
