The Imperial Army Enters

The Undead King Arthur thought to activate his domain skill but he does not want to risk the terrain even more. The Undead King Arthur might not be a full fledge demigod as of now but his domain is still from one of the highest gods.

The terrain will absolutely be affected once the Undead King uses his domain which is why the God of Death explicitly told him to use it only when he is backed into a corner. The Undead King still know that he can win even with the Reaper's Domain active.

"Release the first seal from the Death God's Sword of Devotion." The Undead King Arthur stated and the black blade on his sword suddenly emitted smoke.

The sword that the Undead King is currently wielding has been given to him by the God of Death Abaddon when the covenant was successfully performed. The sword is a divine weapon that the God of Death sent to the Undead King as a token of faith to signify that the latter could be seen as his representative on the mortal plane.
