Darkvision
A monster with darkvision can see perfectly well in areas of darkness and dim light, though such vision is in black and white only. Some forms of magical darkness, such as a 4th-level Darkness spell, block normal darkvision. A monster with Greater Darkvision, however, can see through even these forms of magical darkness.
Form Up
The troop chooses one of the squares it currently occupies and redistributes its squares to any configuration in which all squares are contiguous and within 15 feet of the chosen square. The troop can't share its space with other creatures.
Kinsense (detection, divination, divine)Nightmarchers can detect creatures who are their kin, whether by blood or bond, as an imprecise sense. If they focus their senses on a creature by Seeking, they learn whether they are related to that creature, and how.
Constant SpellsA constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.
Frightful Presence (auditory, aura, emotion, fear, mental)90 feet Aura DC 31 will

Regardless of the result of the saving throw, the creature is temporarily immune to this monster's Frightful Presence for 1 minute.
Critical Success The creature is unaffected by the presence.
Success The creature is Frightened 1.
Failure The creature is Frightened 2.
Critical Failure The creature is Frightened 4.
Troop DefensesThresholds 160 (12 squares), 80 (8 squares)
Troops are composed of many individuals, and over the course of enough attacks and downed comrades, troops shrink in size. Most troops start with 16 squares (4 by 4), and their Hit Points have two listed thresholds, typically the first is at 2/3 their maximum Hit Points and the second is at 1/3 their maximum Hit Points. Once the troop drops below the first threshold, it loses 4 squares, leaving 12 squares remaining, and the first threshold becomes the troop's new maximum Hit Points. Once the troop falls below the second threshold, it loses another 4 squares, leaving 8 squares remaining, and the second threshold becomes the troop's new maximum Hit Points. In order to restore its size and maximum Hit Points, a troop needs to spend downtime to use long-term treatment on casualties or recruit new members to replace the fallen. At 0 Hit Points, the troop is reduced down to 4 squares, which is too few to sustain the troop, so it disperses entirely, with the few remaining members surrendering, fleeing, or easily dispatched, depending on their nature.
A damaging single-target effect, such as a Strike, can't force a troop to pass through more than one threshold at once. For instance, if a troop had 60 Hit Points, with thresholds at 40 and 20, a Strike for 50 damage would leave the troop at 21 Hit Points, just above the second threshold. A damaging area effect or multi-target effect can cross multiple thresholds at once and could potentially destroy the entire troop in one shot.
Non-damaging effects with an area or that target all creatures in a certain proximity affect a troop normally if they affect the entire area occupied by the troop. If an effect has a smaller area or numbers of targets, it typically has no effect on the troop. However, if the effect can target at least four creatures or cover at least four squares in the troop, and if it would prevent its targets from acting, cause them to flee, or otherwise make them unable to function as part of the troop for a round or more, the troop loses loses a number of Hit Points equal to the amount required to bring it to the next threshold, removing 4 squares. If an effect would both deal damage and automatically cross a threshold due to incapacitating some of the creatures in the troop, apply the damage first. If the damage wasn't enough to cross a threshold on its own, then reduce the Hit Points to cross the threshold for the incapacitating effect.
Blazing Admonition
(divine, evocation, fire, visual)Heat scorches those who lay eyes on the nightmarchers. All creatures in a 60-foot cone take 15d6 fire damage (DC 34 basic reflex save).
Prone creatures and the nightmarchers' kin are unaffected as long as they have not taken a hostile action against the nightmarchers.
The nightmarchers can't use Blazing Admonition for 1d4 rounds.
Missile VolleyThe nightmarchers fling a hail of spears and stones, dealing 5d6+9 bludgeoning damage or 5d6+9 piercing damage to creatures in a 10-foot burst within 20 feet (DC 31 basic reflex save).
When the nightmarchers are reduced to 8 or fewer squares, this decreases to a 5-foot burst.
Striking Koa to 
Frequency once per round
Effect The troop attacks with spears, clubs, and leiomano against enemies within 5 feet (DC 33 basic reflex save) for their choice of bludgeoning, piercing, or slashing damage depending on the number of actions.
2d6+2 bludgeoning damage, 2d6+2 piercing damage, or 2d6+2 slashing damage
4d6+12 bludgeoning damage, 4d6+12 piercing damage, or 4d6+12 slashing damage
6d6+12 bludgeoning damage, 6d6+12 piercing damage, or 6d6+12 slashing damage
Whenever the nightmarchers Stride, they first Form Up as a free action to condense into a 20-foot-by-20-foot area (minus any missing squares), then move. This works just like a Gargantuan creature moving; for instance, if any of the nightmarchers' squares enter difficult terrain, the extra movement cost applies to the whole group.
Divine Innate Spells (DC 31, +23 to hit)
4th Level: Air Walk (Constant)
While smooth roads remain a traveler's blessing, walking them after sunset risks nightmarcher attack. The ringing of conch shells and beating of drums herald the coming of these spirits as they walk the royal highways, unfettered by walls or barriers.
Nightmarchers react violently to those in their path. If a bystander is fortunate, an ancestor's spirit might call out to spare them. Those who refuse to show proper deference might be reduced to little more than ash on the wind come sunrise.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
IncorporealAn incorporeal creature or object has no physical form. It can pass through solid objects, including walls. When inside an object, an incorporeal creature can't perceive, attack, or interact with anything outside the object, and if it starts its turn in an object, it is slowed 1. Corporeal creatures can pass through an incorporeal creature, but they can't end their movement in its space. An incorporeal creature can't attempt Strength-based checks against physical creatures or objects-only against incorporeal ones-unless those objects have the ghost touch property rune. Likewise, a corporeal creature can't attempt Strength-based checks against incorporeal creatures or objects. Incorporeal creatures usually have immunity to effects or conditions that require a physical body, like disease, poison, and precision damage. They usually have resistance against all damage (except force damage and damage from Strikes with the ghost touch property rune), with double the resistance against non-magical damage.
