You reduce but do not eliminate falling damage. Instead of suffering 2d6 points of damage per 10 feet fallen, you suffer the minimum 1 point of falling damage per 10 feet. This benefit comes from a magical bounce that occurs at the moment of impact. A successful Jump check (DC 10 + 2 per 10 feet fallen) allows you to control the direction of the bounce; otherwise, the bounce throws you in a random direction from the point of impact. You bounce 2 feet horizontally per 10 feet fallen.
If the direction of a bounce creates a secondary impact with a wall, object, creature, or person, you suffer 1d6 points of damage from that impact and immediately fall prone. A creature struck by a bouncing caster does not suffer damage, but must make an opposed strength check or be knocked prone.
