Shui Gui
CREATURE 5When a person drowns in a body of water, there's a chance that their spirit will be trapped and unable to reincarnate. Twisted with anger, spite, and malice, the spirit transforms into a shui gui.
If someone sees a shui gui from shore, they'll often see only the top part of a head with two pinprick reflections of light from its eyes. Lurking under docks and near the water's edge, the shui gui calls out to people or makes disturbances to draw them within reach of the water. Once the unsuspecting victim is close enough, the spirit pulls them underwater, drowns them, and possesses their body in a process known as ti sh-on. Once the spirit successfully inhabits the vacant body, they escape their curse and live a new life; however, their victim's spirit remains trapped in the water until, at last, they too drown a hapless passerby, thus continuing a never-ending cycle.
A shui gui is terrified of fire, and those who camp by water or travel by boat are advised to always keep a lantern handy. Charms and amulets can also keep the shui gui at bay, but the spirit is generally weakest after being goaded onto land.
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-rank Darkness spell, block normal darkvision. A monster with Greater Darkvision, however, can see through even these forms of magical darkness.
The shui gui is bound to the body of water in which it died. It's unable to move further than 120 feet from the edge of the water.
When the shui gui is destroyed, it reforms after 2d4 days within the body of water it's bound to, fully healing. It can be permanently destroyed if the body of the shui gui who originally died in the water can be found and laid to rest.
A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.
A shui gui can Grapple corporeal creatures despite being incorporeal. The shui gui uses its Athletics check to Grapple as normal but can't use Athletics for other actions that require corporeal contact, like Force Open or Trip.
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.
