Although Albrecht was more or less aware of his opponent's strength, the attack still caught him off-guard since it was more powerful than he had expected. If he had estimated the power output of the blow, he wouldn't have flown all the way, smashing into a tree as he let out a pained groan.
"Am I losing my touch?" Albrecht asked himself as he tried to catch his breath. The attack was easily blockable, but Albrecht misread the power behind it. That's why he was sent skittering backward.
"To think that the human who killed a high-ranking werewolf from the Lycanne Tribe is this weak... this is an embarrassment for our tribe." Severus haughtily let out as he disappeared and reappeared in front of Albrecht.
However, Albrecht was expecting him to repeat his usual movement. After all, Severus was the type to rely on his strengths and he was more straightforward in his attacks so it was easy to foresee what he'd do next.
