Disorientating Beam

You drive a disorientating beam toward one creation that you can see within range.  You can select one of the below effects and the target creature makes the corresponding saving throw.

• Strength: On a failed save, the target is knocked back up to 10 feet from you.  This movement does not trigger attacks of opportunity.
• Dexterity: On a failed save, the target's movement speed is reduced by 10 feet until the start of your next turn.
• Constitution: On a failed save, the target has disadvantage on the next weapon attack roll it makes before the start of your next turn.
• Intelligence: On a failed save, the target must subtract 1d4 from the next saving throw it makes before the start of your next turn.
• Wisdom: On a failed save, the target has disadvantage on the next spell attack roll it makes before the start of your next turn.
• Charisma: On a failed save before the start of your next turn, the next attack roll made against this target has advantage.

At higher levels the number of effects you can apply in a single casting of the spell increases by 1 when you reach 5th level (2), 11th level (3) and 17th level (4).  You can select which of the selected saving throws applies all of the effects.
