Spell Details
Effect
You call forth a guardian spirit from beyond the veil and bind it to guard a location. The spirit is invisible and incorporeal, able to observe the area and communicate telepathically with you if you are within 1 mile. It can sound a mental alarm when specific conditions are met (creatures entering, violence, magic being cast).
Scaling
At 6th level, the spirit can affect the physical world, creating minor sounds or moving small objects to alert you.
Special Notes
You can only have one sentinel spirit active at a time. The spirit has the personality you grant it during the casting.
