You can command the creature by spending actions to control it mentally. Line of effect is required. When controlling, you share knowledge but not senses. As a minor action, you can command the bison to do one of the following, if capable: crawl, escape, fly, open/close a door or container, pick up/drop an item, run, stand, shift, squeeze, or walk. Commanding the bison to attack in battle is a standard action.[PrP:48][PH2:221]
