Gylou

A creature with greater darkvision can see perfectly well in areas of darkness and dim light, though such vision is in black and white only. A creature with greater darkvision can see through even forms of magical darkness.

A monster with telepathy can communicate mentally with any creatures within the listed radius, as long as they share a language. This doesn't give any special access to their thoughts, and communicates no more information than normal speech would.

A 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.

Trigger A creature leaves a square within the gylou's reach using a move action or attempts a melee Strike against the gylou Effect The gylou lashes out with a tentacle, attempting to Grapple the triggering creature. If the triggering Strike was with a melee weapon, the attacking creature can Release the weapon to cause the gylou to automatically fail the Athletics check.

The monster changes its shape indefinitely. It can use this action again to return to its natural shape or adopt a new shape. Unless otherwise noted, a monster cannot use Change Shape to appear as a specific individual. Using Change Shape counts as creating a disguise for the Impersonate use of Deception. The monster's transformation automatically defeats Perception DCs to determine whether the creature is a member of the ancestry or creature type into which it transformed, and it gains a +4 status bonus to its Deception DC to prevent others from seeing through its disguise. Change Shape abilities specify what shapes the monster can adopt. The monster doesn't gain any special abilities of the new shape, only its physical form. For example, in each shape, it replaces its normal Speeds and Strikes, and might potentially change its senses or size. Any changes are listed in its stat block.

Requirements The gylou has a Medium or smaller creature Grabbed or Restrained

The gylou transfers the grabbed creature into their lower body's net of encaging tentacles, freeing their limbs and tentacles to make Strikes. This has the same effects as Swallow Whole (Medium, (2d12+12) bludgeoning, Rupture 30), except the encaged creature is not at risk of suffocation, and the gylou can bring the encaged creature with them when they cast Translocate. A gylou can have only one creature encaged at a time.

Frequency once per day Trigger The gylou attempts a skill check but hasn't rolled yet Effect The gylou demonstrates a preternatural ability for the task at hand. They use their Deception modifier for the triggering check and for all skill checks using the same skill thereafter until the next time the gylou uses this ability or until 24 hours have passed, whichever happens first.

Requirements The monster's last action was a successful Strike that lists Grab in its damage entry, or the monster has a creature Grabbed or Restrained Effect If used after a Strike, the monster attempts to Grapple the creature using the body part it attacked with. This attempt neither applies nor counts toward the creature's multiple attack penalty. The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
