Astral Luggage

1. Portal. The astral luggage can be opened to a two-foot by one-foot opening. This opening repels creatures, prohibiting their entry, but any object you place inside the luggage floats off into the Astral Plane. 
2.  
   Special Fastenings. On the luggage, there are several special fastenings. Unfastening these buckles, zips, or clips causes the portal within the luggage to change its properties the next time it is opened. Each fastening can be unfastened once per day; at dawn each day, all of the fastenings reseal themselves, and the associated properties recharge: 
    
   Optional Attunement. Attuning to this item enhances some of the Special Fastenings properties. 
    
    
   Ebony Clasp. As an action, you can unfasten the clasp and throw the luggage at a point you can see within 30 feet of you, where it instantly opens spewing squirming ebony tentacles in a 20-foot-square. This area becomes affected by the black tentacles spell for the next minute (no concentration required). If you are attuned to the luggage, you are immune to this spell’s effects. When the spell ends, the tentacles disappear and the luggage closes. 
    
   Amethyst Buckle. As an action you can unfasten this buckle and throw the luggage at a point you can see within 30 feet of you, where it instantly opens casting the conjure anomaly* spell. If you are attuned to this item, the aberration conjured is under your control, otherwise the aberration is hostile to all creatures. 
    
   Moonstone Dial. As an action you can turn this dial to a symbol representing a specific plane, and press it, causing it to unfasten. As part of the same action, you can throw it to a point you can see within 30 feet of you, where it instantly opens. Until the end of your next turn, the luggage’s opening becomes a portal to a random location on the chosen plane that Medium or smaller creatures can move through using 5 feet of movement. At the end of your next turn, the luggage folds in on itself and appears next to you on the destination plane.
