Blur.
That's what Krista saw as Eren activated his time-element spell separately and disappeared from his position all of a sudden.
He needed to conserve his mana after all. And Sedating Gaze would only work most effectively when it was used for the first time. It would give diminishing returns and start taking a toll on his mana reserves the more he used on his opponents. Especially if there were more than one of them to deal with.
Repel!
Lambert could feel Eren coming because he had already tagged him with his spell and the tag was still working. He immediately broke Eren's movement spell with a spell of his own and made him appear not too far away from him.
Attraction!
Eren's body was pulled towards Krista from a different direction. The two rankers had already separated at this point. They were planning to launch a two-pronged attack on Eren from two different directions.
