Prerequisite: Ranger, Beast Mastery class feature (lizard)

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 melee basic attack, that creature takes 5 damage if it moves away from the beast companion before the end of the creature's next turn.
