Publication:Dread Codex 2/New Spells/Watchful Ghost

The caster summons one of the lesser ghosts from beyond the worlds to watch over him. This ghost has no powers to attack, but has the following spell-like powers, which it will use to protect its master: detect magic, detect undead and detect thoughts. The watchful ghost can cast these spells 3 times per day, and will use them to answer any question the master may have. These spells are cast as a 3rd level wizard.

Necromancers have been known to summon this ghost to watch over them as they rest or study. The ghost is invisible, and will never show itself to any intruders. It will awaken its master by speaking his name and telling him of the approaching danger. It cannot sense whether an approaching creature is friendly or evil, and cannot see further than a 60 ft. radius around the caster.
