Level: Sorcerer 8, Wizard 8
Components: V
Casting Time: 1 immediate action
Range: Personal
Target: You
Duration: Instantaneous
You borrow a slice of time from the future, pulling it into the present so that you can act.
Upon casting this spell, you can immediately take a full-round action (or a standard action plus a move action, or two move actions). The standard action, if taken, can be as if you had readied an action. You can even interrupt another creature’s turn when you cast this spell. However, after you take the action(s) granted by this spell, you are dazed until the end of your next turn.
