At 3rd level, a precocious companion gains twice as many bonus tricks as normal for an animal companion. A hunter’s animal companion can’t use the additional bonus tricks to learn hunter’s tricks. At 15th level, the DC of the Handle Animal check to push a precocious companion to perform an unlearned trick is only 15, instead of 25.
Ok does it mean at third level ONLY they get double the bonus tricks, or do they double the number of bonus tricks from third level on?
