60 feet. DC 31 will.

A creature that fails its save is also Slowed 1 (Slowed 2 on a critical failure).

---

Devastation

A deep one elder's claw Strikes ignore the first 10 Hardness of an object. Additionally, on a critical hit, the target must succeed at a DC 34 fortitude save or be Stunned 2.

Trample

Huge or smaller, foot, DC 31 reflex

The deep one can Swim up to double its swim Speed instead of Striding.

---

The monster Strides up to double its Speed and can move through the spaces of creatures of the listed size, Trampling each creature whose space it enters. The monster can attempt to Trample the same creature only once in a single use of Trample. The monster deals the damage of the listed Strike, but trampled creatures can attempt a basic Reflex save at the listed DC (no damage on a critical success, half damage on a success, double damage on a critical failure).

Watery Void (concentrate, manipulate, occult, void, water)

The deep one elder makes an endless void of water appear in a 20-foot burst within 60 feet, dragging creatures down into its whirlpool. If cast underwater, the watery void fills a 60-foot-tall cylinder with a 20-foot radius. Creatures in the area when the void appears and creatures that end their turn in the area take 3d8 bludgeoning damage and 3d8 void damage and must attempt a DC 31 reflex save. The void remains until the end of the deep one elder's next turn. The deep one elder can Sustain the void to extend the duration by 1 round, up to a total of 4 rounds, and can move the void up to 15 feet. Once the effect ends, the elder can't use Watery Void again for 1d4 rounds.

---

Critical Success The creature is unaffected.

Success The creature takes half damage and a –5-foot circumstance penalty to their Speeds while in the void.

Failure The creature takes full damage and a –10-foot circumstance penalty to their Speeds while in the void.

Critical Success The creature takes double damage, is knocked Prone, and takes a –10-foot circumstance penalty to their Speeds while in the void.

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 [/act trip] the creature as a free action. This attempt neither applies nor counts toward the monster's multiple attack penalty.

---

Given enough time, deep one elders can swell to dizzying heights.

---

Lumbering, amphibious, and deathless humanoids known as deep ones inhabit coastal areas and deep ocean trenches all across Golarion. Though most simply wish to be left alone, others work tirelessly to grow their ranks.
