This is Inquisitor Lavellan in the Flames of Inquisition armor, wielding the Staff of the Dragon from Dragon Age Inquisition. The armor is made from deer skin which was stretched, painting and sewn by hand. The shoulder pads, scales on the sleeves, chain and other metal-looking accent pieces are made from Wonderflex. The dragons on the front of the armor were sculpted and then cast with Smooth Cast 300.
