Prerequisite: Ranger, Beast Mastery class feature (cat)
Benefit: Your beast companion gains a +2 bonus to saving throws.
While your beast companion acts independently, it need not move adjacent to you but must remain within 10 squares of you.
In addition, if it hits a creature with a charge attack, it can make an additional melee basic attack against that creature as a free action.
