Timez

Timez is a Dark Magic that allows its caster to manipulate time.

Description
Timez enables its caster to rewind, accelerate or to stop time. In addition to manipulating time itself, if used with the Summon Chronos, it also enables its caster to create watch hands to attack their targets.

Timez is stated to be the most powerful magic, likely due to the difficulty of fighting against time itself.
