Slow Metabolism
A water orm can go for 10 years without feeding. Beyond this limit, the water orm's hunger causes it to become Slowed 1 but doesn't otherwise impact its lifespan. A water orm that's slowed as a result of starvation can remove this condition by using Swallow Whole to gulp down a meal.
Undetectable
A water orm automatically tries to counteract any detection, revelation, or scrying ability attempted against it, using its Stealth modifier for the counteract check.
Swallow Whole
Large, (2d8+8)[bludgeoning] damage, Rupture 22
Water Travel
A water orm can dissolve into water, appearing only as a long, dark, serpentine stretch of liquid. While in this form, a water orm's swim Speed increases to 600 feet, it automatically succeeds at Athletics checks to Swim, and it gains a +4 circumstance bonus to Stealth checks in water. A water orm can remain in this form for 8 hours, but it can't enter salt water when using this ability. A water orm can return to its normal form by Dismissing this action.
