SPECIAL ABILITIES

Capsize (Ex)

A sea serpent can attempt to capsize a boat or ship of its size or smaller by ramming it as a charge attack and making a combat maneuver check. The DC of this check is 25 or the result of the boat captain’s Profession (sailor) check, whichever is higher.

Elusive (Su)

Sea serpents have long been the stuff of maritime legends, but despite countless attempts to hunt them, they are rarely encountered unless they wish it. As a full-round action while in water, a sea serpent can move up to its run speed (300 ft.) without leaving any trace of its passing. An elusive sea serpent gains a +40 circumstance bonus to its Stealth check. In addition, except when in combat, a sea serpent is considered to be under the effects of a nondetection spell. Both of these spell effects are at caster level 20th and cannot be dispelled.
