Warpwhiz
The Time Lords fled from the empire as soon as the hell portals opened, leaving nothing but a trail of time-space dust in their wake. A small number of time keepers, though, could not reconcile the dereliction by the Time Lords with their duty to preserve the time stream and thus all of creation, and returned to help the survivors with their chronokinetic magics while picking up the silly title of Warpwhiz.
The Warpwhiz is a ranged damage spellcaster. However, while they do have some damaging spells, their focus is not dealing damage. Rather, the class is dedicated to indirect battlefield manipulation and control through things like rearranging combatants, rerolling dice, swapping targets' hit points, and more.
