Yshula

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.

Pairakas hate the color red. They won't wear the color or willingly enter any place painted red. Given a choice, they'll attack a creature wearing red first. If barred from expressing their displeasure toward the color by force or some magical effect, they take 2d6 mental damage at the end of their turn.

A creature can't remove the Fatigued condition while infected

Yshula can take the appearance of any Small or Medium humanoid or animal. This doesn't change his Speed or his attack and damage modifiers with the Strikes, but it might change the damage type his strikes deal.

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.

Yshula is Drained 2 and can't recover from his drained condition while he's in the cottage. These reductions are included in his statistics.
