You can cast spells that blast creatures off their feet.

Prerequisites: None

Benefit: On a failed Reflex save, an explosive spell ejects any creature caught in its area, sending it to a location outside the nearest edge of that area, dealing additional damage and further knocking creatures prone. If some obstacle prevents a blasted creature from being moved to the edge of the effect, the creature is stopped and takes 1d6 points of damage per actual spell level. In any event, this movement does not provoke attacks of opportunity. Explosive Spell can be applied only to spells that allow Reflex saves, affect an area (a cone, cylinder, line, or burst) and have the fire, sonic or force descriptor.

A less displayed spell uses up a spell slot one level higher per removed display than the spell’s actual level.
