I can’t prove it because i didn’t record or take a screen shot. But for those that are curious.
Santa’s workshop DOES drop reskins. when you reach the 3rd room. destroy the middle present in the room and a random one will drop.
i was only able to do this once, so you have to be fast and keep an eye on your minimap.
my best suggestion is bring a bunch of att, dex, and spd buffs with you before you start.
again, i repeat, Santa’s Workshop drops reskins!
