You can strike your foes with incredible force.

Prerequisite(s): Vital Strike.

Benefit: Whenever you use Vital Strike, Improved Vital Strike, or Greater Vital Strike, multiply the Strength bonus, magic bonus, and other bonuses that would normally be multiplied on a critical hit by the number of weapon damage dice you roll for that feat.

Extra damage from sources that wouldn't normally be multiplied on a critical hit isn't multiplied by this feat.
