Rusalka

Rusalkas are cruel and bitter fey who inhabit waterways near humanoid settlements. Although rusalkas are not undead, some persist in believing that these fey form from the spirits of those who met a sinister end in the water. Rusalkas do little to dissuade such rumors. Rusalkas are fond of keeping a few charmed monsters or powerful humanoids nearby to aid in their defense or for other forms of cruel and humiliating entertainment, but quickly grow bored with such pets. When this occurs, rusalkas generally murder the creatures and seek more interesting replacement pets.

Beckoning Call — As a standard action, a rusalka can sing or speak, causing all non-fey creatures within a 300-foot spread to approach its position as if compelled to do so via a suggestion spell (DC 27 Will negates). A creature that successfully saves is not subject to the same rusalka's beckoning call for 24 hours. When an affected creature begins its turn adjacent to the rusalka, it is dazed for that round. These effects continue as long as the rusalka takes a standard action to maintain the effect, plus 1 additional round. This is a sonic mind-affecting effect. The save DC is Charisma-based.

Tresses — A rusalka's long hair is strong and capable of making powerful primary natural attacks. When it uses its tresses to grapple an opponent, a rusalka does not gain the grappled condition itself. In addition, a rusalka uses its Charisma modifier in addition to its Strength modifier for all combat maneuver checks made with its tresses.
