Whenyou cast this spell, you step outside the normal time stream, seeming to vanish as 1 round of time passes. You can make minor alterations to the scene being played out, becoming visible for an instant each time you make an adjustment that aids an ally or hinders foes. To everyone else, you disappear when the spell is cast, then flicker into and out of view during the next round, before reappearing for good in the space you vanished from 1 round later, whereupon the spell ends. You cannot be attacked by any means while under the effect of this spell. As the round progresses, you can choose to bestow a single effect on each creature involved in the combat, choosing from the list below. You can bestow different effects which cause a specific creature to be affected multiple times, but only as a single effect per creature. You cannot take any other actions during the round.

• Give a creature advantage or disadvantage on a saving throw it is about to make.
• Give a creature advantage or disadvantage on an attack roll it is about to make.
• Alter the location of a mobile object to provide or remove cover for a creature.
• Shift objects into the path of a creature; the first 10 feet of terrain it must travel becomes difficult terrain.
• After an attack roll is determined to be successful, adjust the angle of the strike or the positioning of the target, either causing the strike to deal half as much damage or providing a bonus to damage equal to half your level.
