He looked at his first Umbral servant and, without an ounce of mercy, he turned him into ash with a solar pulse fired from his palm.
The servant's darkness coating resisted for a little bit, but still... it got devoured by the intense solar pulse in no time... Then, he turned around and left.
As Ash'Kral said, if overusing Darkness Coating was a serious problem, he wasn't going to waste his limited slots of servants on a nobody.
'Damn, even solar-based abilities burn as hell.'
While he was flying away, he glanced at his crimson soles and some skin burn marks on his legs... his resistance to sunflames was decent, but not decent enough to protect him from genuine sunflames touching his flesh.
His mind returned to the scene of him using a camouflage-based totem to cover his presence while he hid behind a cracked mound... he wanted to ambush them using Sun Jets to see just how fast they would make him go.
