Kyton, Terpsikhore

Terpsikhore Kyton CR 1

A slender form riddled with nails and taut wires creeps through the shadows. Its toothless mouth gapes in a silent scream and its needle-thin nails pluck at the wires like some nightmarish lyre.

Choir of Many (Su)

As long as there are at least two terpsikhore within 100 ft. of each other, if one creature in the chorus is aware of a particular danger, they all are. No terpsikhore in a group is considered flat-footed unless they all are. Only roll initiative once when encountering terpsikhore kytons. Terpsikhore always act on the same initiative.

Harmony of Agony (Su)

Two or more adjacent terpsikhore can create a discordant song that gains power based on the number of terpsikhore joining in, up to a maximum of ten terpsikhore contributing to a single effect simultaneously.

Performing a harmony of agony is a full-round action for each participating terpsikhore. The caster level of these effects and saving throw DCs are listed for each individual effect and is based upon the number of participating terpsikhore (see the accompanying table below). Despite the sound-based nature of these effects, terpsikhore can use this ability in areas affected by silence or that are otherwise soundless (such as the vacuum of space). All participating terpsikhore must be at least within 10 ft. of another terpsikhore in the group. Not all terpsikhore are required to participate, for example a group of ten can use an effect that requires lesser creatures and permit the others to take different actions.

Incomplete Kyton (Ex)

Terpsikhore are made from fragmented souls and lack a complete essence.

Despite possessing the kyton subtype, they lack the regeneration and unnerving gaze abilities.

Unified Front (Su)

Terpsikhore move and fight as one. Whenever a terpsikhore is adjacent to another of its kind, they share their total hit points in a combined pool by swiftly sharing molten flesh and organs. If the terpsikhore move apart they divide their remaining hit points equally (rounding down). Similarly, adjacent terpsikhore raise the saving throws of the entire collective, but only to the extent listed on the accompanying table (these altered saving throws don’t increase with additional terpsikhores). A group of terpsikhore use their total combined CR to determine if they are affected by effects that vary based on a target’s CR.


Environment any (The Shadow plane)
Organization solitary, pair, or chorus (3-20)

Harmony of Agony Effects

# of Terpsikhore Effect
2 A wailing cry of agony blasts one creature with the squeal of tortured metal. This acts as inflict pain (2nd-level, DC 12), using any one contributing kyton as the point of origin for the effect. Two adjacent terpsikhores do not synergize their spell-like ability DC or saving throws.
3 The terpsikhore release a wailing shriek in an eerie harmony. Select one of the contributing kytons as a point of origin. Every terpsikhore kyton within 100 ft. of the origin creature, whether participating or not, gains a +1 bonus to weapon attack and damage rolls. This effect lasts for 1 minute. Three adjacent terpsikhores have the following saving throws; Fort +4, Ref +2, Will +6.
4 The terpsikhore invoke the implacable function of the Machine with a chittering cry, drawing upon its perfect designs to rebuild the bodies of their kyton kin. Select one of the contributing kytons as a point of origin. All kytons within 30 ft. of that kyton (participating or otherwise) are healed as per mystic cure (3rd level) for 5d8 points. Four adjacent terpsikhores have the following saving throws; Fort +5, Ref +3, Will +7.
5 The terpsikhore let out a sudden and startling scream. Select one of the contributing kytons as a point of origin. All enemies CR 5 or lower within 30 ft. of that creature must succeed at a DC 14 Will save or become dazed for 1 round by sudden, stabbing pain. Five adjacent terpsikhores have the following saving throws; Fort +5, Ref +3, Will +7.
10 The terpsikhores’ chant tears at weak psyches, peeling away resolve and spirit. Select one of the contributing kytons as a point of origin. All non-kyton creatures within 20 ft. of that kyton must succeed at a DC 15 Will save or be affected by fear (4th-level). Ten adjacent terpsikhores have the following saving throws; Fort +6, Ref +4, Will +8.
