Oddly enough, this robe--sold proudly by the Fantasy Costco staff, created by Garfield the Deals Warlock himself--shows no odd coloration or stitched patterns emblematic of the franchise. As a one-of-a-kind creation, one could assume that the priority was to emphasize its unique properties but downplay the appearance and value. As such, this rather plain garment has loose sleeves and a long drape in the back, affording mild protection from the elements and excellent air flow.
Of course, this accessory is infused with energies that actually cause the robe to cinch and tighten based on movement; when the situation requires it, the fabric of the Robe of Avoidance responds artfully, demanding that its wearer enter combat with the intention to close distance and engage in melee combat. It confers a +2 bonus to AC against ranged attack rolls while worn. In addition, the Magic Missile spell now requires a ranged attack roll against the robe's wearer. Lastly, if a weapon attack misses, the wearer capitalizes on the robe's enchantments and takes advantage on their next attack roll against the attacker, before the end of the next turn.
