Sacrifice

"Teleport them somewhere! Hurry! I can't hold on any longer!" Lumiel screamed with all his might. His throat was about to explode as he shouted.

Immediately, the duplicate hurried. Thinking that time was of the essence, he started casting his skill.

Soon after, Isaias and the carriage was glowing. The duplicate included but not Lumiel. A split-second late will make them covered with boulders so Lumiel maintained the [Telekinesis]. Lumiel could be included in the teleportation but he needs to repel the boulders. If he was included in teleportation, his skill will be interrupted. It will only be possible if he has higher skill. But for now, it was impossible.

Higher teleportation skill will make you have faster casting speed, longer range, and can be used in battle, can't be interrupted, and, instantaneous transport while doing or maintaining other skills.
