Dazing Spell

You can modify a spell to daze a creature damaged by the spell. When a creature takes damage from this spell, they become dazed for a number of rounds equal to the original level of the spell. If the spell allows a saving throw, a successful save negates the daze effect. If the spell does not allow a save, the target can make a Will save to negate the daze effect. If the spell effect also causes the creature to become dazed, the duration of this metamagic effect is added
