Dominus Formidulosus, Roblox Wiki

Dominus Formidulosus is a hat that was published in the avatar shop by Roblox on October 30, 2019, specifically for Halloween. It could have been purchased for 13,000 Robux on a 1-day and 7-hour timer and became limited shortly after going off-sale, being the first Dominus to do so since 2017
