Evocation [force]
Tier: 2
Components: Verbal, Somatic
Casting Time: 1 major action
Range: 60 ft
Effect: One invisible blast of force
Duration: Instantaneous
Saving Throw: None
The spell throws the creature backwards, smashing him into the wall.

This spell creates an invisible (save for dust and debris disturbed by its passage) blast of magical force, which flies from your hand as a ray. If you strike a creature with a ranged touch attack, the ray deals 1d6+1 points of damage and may force the target back (or break through a door or other obstacle). Roll a Strength check for the spell with a bonus of +8, opposed as normal for a bull rush.

If the spell is used against an object, to can break the object (use the same Strength bonus). A light, poorly secured object is more likely to be sent flying.

Augment:
For each additional spell point you invest, you can increase the damage by 1d6 (up to a maximum total of [½ caster level] d6). For each extra d6, the spell gains an additional +2 bonus on the Strength check.
