Canopic Sentinel Jar

Wondrous item, very rare (attunement required)

These clay jars are inscribed with sigils of life and fertility and are colored in vibrant faience greens and blues. Each attuned canopic sentinel jar can be further bonded to a single creature in a ritual which takes 1 hour. During this ritual, one of the four canopic organs (lungs, intestines, stomach, and liver) is removed from the creature wishing to be bonded and placed inside the jar. During the ritual, the creature is sustained by the jar’s magic and suffers no ill effects from the organ’s removal. A creature can be bonded to up to four such jars, each jar containing one of the four organs. A creature may be attuned to up to four jars while counting as only one item for attunement limit purposes.

When a critical hit or sneak attack is scored on a creature bonded to one or more jars, there is a chance that the critical hit or sneak attack is negated and damage is instead rolled normally. The chance is 20% for each jar the creature is bonded to. For each jar a creature is bonded to, they reduce the amount of healing received by spells and abilities by 2 (2 hit points for 1 jar, 4 hit points for 2 jars, etc) to a minimum of 1 hit point of healing as each missing organ disrupts the flow of magical healing.

A canopic sentinel jar must remain within 200 feet of the creature it is bonded to. If it is moved beyond this range, the organ inside is immediately transported back into the bonded creature. If the jar is opened manually (a full-round action when in possession of it), the contained organ returns to the bonded creature. Smashing the jar (hp 20) also causes the interred organ to return. The jar can be placed in an extradimensional space, but doing so causes the organ to return to the bonded creature.
