Wondrous Item

Legendary

As a bonus action, you can toss the device into the air, whereupon it floats at a distance of 1d3 feet from you and you can access its properties.
The device has AC 22, 25 hit points, immunity to poison and psychic damage, and resistance to all other damage. It is considered to be an object that is worn while it is floating near you.
Imperfect Shift You can use an action to activate the Astrarium, whereupon it's rings spin rapidly and it creates a two-way portal to another world or plane of existence. Each time the item opens a portal, the DM decides where it leads. You can use an action to close an open portal by taking hold of the sphere and folding it up. Once the Astrarium has opened a portal, it can't do so again for 1d8 hours.
Planar Knowledge. The device knows basic, useful information about the planes of existence. While the device is floating, it verbally answers questions you or anyone you designate poses to it about that topic. It knows the information about the planes in the Dungeon Master's Guide, as well as basic information about the gate-towns of Sunset Valley
Cosmic Determination. The Astrarium gains new abilities depending on your Devotion to Obscura.

DEVOTION 10+

You can use this Astrarium to learn the history of a specific object or creature by taking an action to gaze into its center and think of the target, presenting you with scenes from the target's past. Information conveyed is accurate, but it is random and cryptic, and presented in no particular order. Once it is activated, the mirror gives its information for 1 minute or less, then returns to normal. It can't be used again until the next dawn.

DEVOTION 25+

You may use am action to cast Contact Other Plane without expending a spell slot. Once you do so, you cannot do so again until the next dawn

DEVOTION 50+

Perfected Shift While the Astrarium is active, you can use an action to name a location that you are familiar with on another plane of existence. Then make a DC 15 Intelligence check. On a successful check, you cast the Plane Shift spell. On a failure, you and each creature and object within 15 feet of you travel to a random destination. Roll a d100. On a 1-60, you travel to a random location on the plane you named. On a 61-100, you travel to a randomly determined plane of existence.

This astrological device is made of 16 interlocking Armillae rings, each representing a cosmic Plane, orbiting around a hollow center where it would appear a 2-inch wide sphere is meant to be inserted.


The device weighs 5 pounds and is covered with subtle etchings of planar sigils.
