Chained spirits, sometimes referred to as chain spirits, are phantoms that failed in life to guard a certain place that has resulted in their death. After they die, their spirit is bound to the place they were supposed to guard, unable to move any distance from it. They are further secured in place by spirit anchors which both trap them in place as well as increase their power.
A chained spirit appears much like any phantom—incorporeal and faint—however they are made more distinctive by the heavy chains that wrap around their body and stretch off into the ether. Some seem to stretch away from the chained spirit through walls and ceilings whilst other seem to collect and pool on the floor beneath it. They appear to be constricting and crushing the chained spirit as if in eternal punishment.1
Habitat and ecology
Chained spirits can create spirit anchors by binding as many as four nearby evil sentient creatures. Each spirit anchor makes the chained spirit more evasive and resilient, and the chained spirit can use its anchors' senses as though they were its own.
A chained spirit cannot be permanently destroyed until all of its anchors are also destroyed. However, these anchors also eternally bind the spirit in place. As long as it has at least one spirit anchor, it is unable to move without being returned to its prison within a few seconds.
The chains that anchor a chained spirit to the Material Plane are real, and it can use them to lash out it its opponents with magical powers. These chains regenerate on their own within seconds if broken.12
