At 6th level, when outdoors, a falconer can direct his feathered companion to strike an enemy from high above. His feathered companion gains the following trick as a bonus trick.
Swooping Charge (DC 20; bird)
The falconer's bird companion flies up and then swoops down into a charge. To perform this trick, the companion must be able to fly, and it must be outdoors or someplace with enough room for the bird to fly great distances in (a grand cathedral may have enough room, but dungeons usually do not). It spends a full-round action flying to a high vantage point, and on the next round makes a charge attack upon an enemy the falconer designates. If that charge attack hits, the bird deals 2d4 points of damage instead of 1d4 with its bite and gains a ×4 critical modifier when making the attack. If the bird hits, the target is staggered for 1 round. This ability replaces the combat style feat the ranger gains at 6th level.
