Arkhalis' Hood

Nothing crafts or sells these. They fall out of the bags Hardmode bosses leave behind, on a rare roll, so the way to finish the outfit is to keep beating bosses you can already handle rather than hunting one fight. Queen Slime never carries developer gear. Those bags exist only in Expert and Master worlds, so a Classic character will never see the set. A winning roll also hands you her wings and Arkhalis itself.

The clothing goes in social slots and changes nothing about your stats. What separates it from the other developer wardrobes is that it takes its color from your undershirt, so two players in the same outfit rarely look alike. The sword follows the same rule. Its beam picks up that color, and with Arkhalis' Bodice worn the beam is drawn wider, though the hitbox is unchanged and you gain no reach.

The set was made for Arkhayla, who ran quality at Re-Logic. The line about not getting it from the Grid points at Tron: Legacy, and it is phrased to rhyme with the joke on the sword. The blank face under the hood is its own sprite effect rather than part of the helmet art.
