A collaborative effort from Episode and Dungeons & Dragons, the Mindflayer t-shirt is released in a black and green colorway with a detailed, screen-printed graphic on the chest and repeats the co-branded graphic much larger on the back. The illustration displays a twenty-sided die above an "illithid" humanoid monster (both from the fantasy board game), brandishing oily tentacles and sharp claws for a unearthly, aggressive look.
