Time dash

For two rounds you temporarily change the flow of time around you, gaining increased speed and reaction time.

During this time your movement speed is doubled, and you have advantage on dexterity saving throws. Further more you can expend a spell slot of fourth level or higher to gain an extra action excluding spells.

During this time you can also use your reaction and a spell slot to use the deflect missiles ability, the same way as monks however using your intelligence rather than dexterity.
