Lacerating Maul
Ranger Attack 5

Opening your quarry up with a decisive attack, you allow your beast companion to tear a wound. The scent of blood eggs the beast on.

Melee weapon

Target: One creature

Attack: Strength vs. AC

Hit: 2[W] + Strength modifier damage
Beast: If your companion is a bear, a boar, or a lizard, the attack deals extra damage equal to your Wisdom modifier.

Miss: Half damage.

Effect: If the target is your quarry and your beast companion is adjacent to it, the target takes ongoing 5 damage (save ends). Until the ongoing damage ends, the target grants combat advantage to the beast.

Lacerating Maul is a daily power available to rangers at the 5th level.[MP:47]
