Drown (Su): A nereid can make a special touch attack to try to fill an opponent's lungs with water. The opponent can resist this effect with a DC 16 Fortitude save. On a failed save the opponent begins to drown. The save DC is Charisma-based and includes a +2 racial bonus.
Spell-Like Abilities: At will - air breathing (DC 16); 3/day - control currents; 1/day - control water (DC 19), wall of ice (DC 17). Caster level 10th. The save DCs are Charisma-based.
Summon Water Elemental (Sp): Once per day a nereid can attempt to summon 1d3 Small water elementals or a single Medium water elemental. The summoned elementals remain for 1 hour or until slain. This ability is the equivalent of a 5th-level spell.
Deflection (Ex): A nereid adds a deflection bonus to AC equal to its Charisma bonus.
Displacement (Su): A nereid's shimmering form makes its true location difficult to surmise. Any melee or ranged attack directed against it has a 50% miss chance unless the attacker can locate the nereid by some means other than sight. A true seeing effect allows the user to see the nereid's position, but see invisibility has no effect.
Shawl (Su): Every nereid is wrapped in a delicate shawl of seafoam white, to which its essence is bound. A nereid whose shawl is destroyed quickly fades and dies within 1 hour. Cruel individuals coerce the service of nereids by stealing their shawls, and a nereid so deprived will do everything in its power to regain the item. A nereid's shawl can be taken while it is worn by using the disarm action, though this is a difficult task. Treat the shawl as a well-secured item, which means that you must first pin the nereid before you can use the disarm action (and even then, the nereid gains a +4 bonus on its roll to resist the attempt).
Speak with Animals (Su): Nereids can speak with animals, though only simple concepts can be communicated (as the speak with animals spell).
Skills: Nereids have a +8 racial bonus on Hide checks underwater because of their near transparency while submerged.
A nereid has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.
A nereid relies on concealment and camouflage to avoid danger, and it does not attack unless in the most desperate circumstances (such as retrieving a stolen shawl). Nereids use their water magic to hold back attackers and summon elemental allies to assist them in combat.
