Sila and the Death Knight were immediately locked in combat high in the skies. One was Divine, and the other wasn't, but you could hardly tell.
Sila sent a double-handed palm strike into the Death Knight's armour, shot stepped forward to close the distance, landed a barrage of jab punches into its chest with [Tamed Knuckle; Charged Frenzy] in an attempt to shatter its sternum, and then tackled it when it attempted to grapple him. The two fell… only for the Death Knight to cackle and release a pulse of Undeath energy that pushed Sila off its body.
Once the distance was established between the two, the Death Knight conjured more Mirrors around it in a remarkably short time, grabbed one, and flung it at Sila. Serenity's Free Marauder couldn't react in time. He was slightly slower than the Death Knight on the whole. The Mirror slammed into him. While this didn't harm him, the Death Knight's next move did.
