Obcasus is a tall, broad man, reaching a height of 6'3", in his late 20s or early 30s.
He is typically seen wearing a charcoal-coloured skull mask under a low-hanging hood, but removing the mask reveals a face of pale skin and sharp, blue eyes. Both his beard and long, unkempt hair are almost jet black and several grey or white hairs are peppered through it.
Around his neck is an amulet bearing the symbol of the Church of Jergal, however his other equipment and style of combat suggests he is no priest or paladin.
