The exclusive psychic abilities of the Spirit Traveler, which Gaven had already explored extensively through his profession as a Mage, were not difficult at all to master. It only required a bit of time for psychic imprinting.
What truly attracted him were group time jump and time rewind, which were not merely teleportation abilities, but a form of time manipulation.
In the multiverse, any ability involving time is incredibly formidable; if used well, it often can have a surprising effect.
For example, this group time jump can make the recipients disappear from the timeline for a certain period, and then reappear collectively.
In combat, this move is not very useful, but what if it is used in an ambush?
In different situations, the enemy's defenses vary.
One can fully exploit the time difference to catch the enemy off guard.
Compared to time jump, time reversal is even more challenging.
