Trigger A creature moves from beyond the reach of the benthic reaver's tail to within the reach of the benthic reaver's tail
Effect The benthic reaver makes a tail Strike against the triggering creature and can use Improved Knockdown if the attack hits, even if it isn't the benthic reaver's turn. If the benthic reaver knocks the target Prone, it disrupts the triggering move action.
Void Healing
A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Numbing Ice(cold)
A creature who takes damage from the benthic reaver's eye beam Strike must succeed at a DC 41 Fortitude save or become Slowed 2 as cold stiffens its limbs. A flying creature who fails its save also descends safely to the ground below. This is forced movement.
Song of the Lost(arcane, auditory, emotion, fear, mental)
The benthic reaver unleashes a cry of mourning. All creatures within 60 feet must attempt a DC 41 Will save to resist. The benthic reaver can't use Song of the Lost for 1d4 rounds.
Critical Failure As failure, but the creature is also Stunned 1 with sympathy.
Tail Sweep
The benthic reaver makes a tail Strike against each enemy within its reach. These attacks count toward the benthic reaver's multiple attack penalty, but the multiple attack penalty doesn't increase until after the benthic reaver makes all its attacks.
Improved Knockdown
Trigger The monster's last action was a successful Strike that lists Improved Knockdown in its damage entry
Effect The monster attempts to Trip the creature as a free action. This attempt neither applies nor counts toward the monster's multiple attack penalty.
