Phylactery of Monstrous Attention

This religious arm wrapping appears to grant a beneficial power but is cursed.

Curse of Monstrous Attention. [strong curse] Anyone that casts cleric spells that touches the phylactery first (even if using gloves or implements) will become the host, believing it to be a helpful item (no save). The host suffers from the following:

• Any extra-planar creature within 600-ft. radius that is the opposite alignment of the wearer (on both axes) will immediately know exactly where the wearer is located and that they are an enemy. This knowledge remains while within the area of effect. Extra-planar creatures have no additional knowledge regarding the wearer.

• If a cleric of 10th level or higher becomes the host of the phylactery, they will attract the enmity of an extra-planar being of great power (solar, titan, arch-devil, demon lord/queen/prince, slaad lord, the oinodaemon, elemental prince/princess, etc.). This being will immediately begin to work against the wearer, targeting allies and loved ones, foiling or ruining plans, assisting the wearer's enemies. Should any of this affect the wearer's religion, the religion's goals, or the wearer's allies (particularly if Good), then the wearer must seek atonement even if the curse is removed (and may lose standing with their deity which could affect spell access).
