Wizard Arcane Tradition: School of Chronomancy

From publisher blurb: Those who study the arcane have always found their spells to be most effective in manipulating the present. However, the existence of divination spells demonstrates that the future and past can also be affected by magic, and Chronomancers extend their arcane discipline to manipulate time to their advantage. Building off of the existing Fifth Edition rules to build a wizard character, the School of Chronomancy gives you options to build a chronomancer, manipulating the flow of time around them to produce potent aftereffects on the spells they cast.
