As Daniel's bolt flew through the air, the mage's lightning bolt tore through it and blasted a chunk out of the ceiling, at the same time as he stood and fired a single bullet at him. The round travelled across the expanse as he swiveled to avoid it, but the bullet tore through his side, shattering the ice that made his magical barrier as it sped through and past him. The impact knocked him to the floor with a grunt of pain but it otherwise did not harm him. 

However when he stood the mage was gone. He'd run off to the right, last he'd seen. The wolf ran to his left, matching the direction as he ran to the edge of his platform where he saw the errant caster, floating downward by magic as he readied a shot straight at him. 

Upon seeing the gun he dropped to the floor again, raising his pistol in that general direction as he stood again, in a crouch as he caught sight of his opponent once more. With gun raised, he emptied the magazine at the floating mage while channeling a simple ice magic into his left hand. The first bullet went straight and slightly left of Metz's center of mass, the second flew high and right, and the third went low and right, most likely to miss. 

And immediately after that, he flung the gathered ice in his hand at the mage. The magic expanded in the air, forming sharp shards of ice that flew like shrapnel towards the mage in a cloud of ice.

He kept in a crouch, minimising his profile to the gun mage. Hopefully he'd finish the fight with this.
