Combat Beast Master
You have trained your beast to fight, defend you in battle, and bring down fleeing suspects.

Benefit: Your working beast has been trained to be an especially effective combatant for its size. Thanks to an excellent exercise regimen and scientifically formulated diet, your beast partner’s beast level improves by +1, possibly increasing its size and combat statistics. Your beast is fiercer and more aggressive than normal, and will fight to the death to defend you or a creature you designate.

As a move action (or as two swift actions), you can direct your beast in combat through shouted commands and gestures, telling your beast exactly where to bite and how hard. Doing so allows you to substitute your Persuasion check result for your beast's melee attack or grapple roll. You may only use this ability once per round, and may not use this ability if and when your animal makes a full attack action.

Special: If your original beast partner is slain, you may apply the benefit of this feat to a new beast companion.
