Theo had torn the leg of his trousers and silently uttered the incantation with his wand pressed up against his thigh. Skin peeled back like fire claiming the edges of torn parchment, licking its way across the surface it disappeared with a putrid smell, not unlike burning hair. Where Bill Weasley had been limited by a fast paced duel and his severely lacking magical abilities. Theo was not. The soulbond allowed his magic to penetrate the upper layer of skin and then burrow down deeper, creating pockets of burnt out flesh and the acrid decay of infection. This all happened within seconds, the spell worked its way across one thigh and crept its way up towards his middle, devouring everything in its path.
