The skeleton on the right is obliterated by the force of the Deadra's sheild punch. However, out of the shadows leaps the other skeleton, which has apparently won is conflict with the Scamp. With a hiss (or whatever sound skeletons make...) it burries its silver dagger deep into the Dremora's chest, latching on to it like some sort of parasite.
Silver...
If there were any metals that stood a chance in hell of breaking through Daedric, it was Silver, Ebony, and the Coppery Dwarven material. Silver's magical properties aided it, and the the bronze of the Dwemer was strong. Ebony was the base material of Daedric objects, so it stood to reason.
That, and the skeleton got lucky, the dagger slipping through one of the few spots in the Daedric Armor that was open; the chain-link mesh just under the briastplates, connecting to the plates over the stomach. The silver pierced into flesh, but didn't get far as it became wedged between the plates it had slipped between. Daedric armor was renowned for the expert chain-plating that covered nearly every inch of the body in hard metals.
The Kynval roared in pain as the blade pierced between ribs and managed to puncture the lung. Recoiling back a step, the Daedra hunched over, the skeleton still grasping it in an embrace of death. Looking at the glowing red eyes through its own helm, the Dremora snarled, and tried to headbutt the skeleton off.
But whether or not it would be successful was irrelevant. The Dremora had stumbled back, closer to Kurrian, and the Frost Atronach deemed this to be too close. Thudding forward, the massive icicle blue hands spread wide, before the Atronach brought them together to clamp down on the combatants.
