Uninvited Guest

You must be actively scrying on a non-good aligned humanoid to cast this spell.

You temporarily force your will onto the mind of another. The target must make a Wisdom saving through or have their consciousness suppressed, and yield all of their abilities to the caster for the duration of the spell, including access to any spells that would be within the caster’s ability to use. Chaotic and evil targets have disadvantage on the saving throw to resist the control. Good aligned creatures automatically succeed on their saving throw.

This spell cannot target the same creature more than once in the span of a week, as the disruption to the creature’s spirit and neural pathways leaves them in such disarray that a Scrying spell cannot “recognize” them until several days have passed. This disruption of a creature’s neural pathways and spirit, along with the juxtaposition of their soul with the caster’s, results in the target being immune to all forms of scrying (and therefore further castings of Uninvited Guest) for 24 hours after the spell expires.

This item is a modification from the item in "The Mask of Death" module.
