Gatecrasher Charm (rare)
Bind a ghost in salt, then destroy it (rare). Collect the salt afterward.
This delicate arrangement of arctech clockwork gears of rusted iron is assembled from the reflection of real-world metals found in the Bleak Gate. Its gears constantly, silently spin despite their corrosion.
While the charm is on your person and you are on the Waking or in the Dreaming, as a bonus action, you can mentally will this charm to irreparably break itself apart. After a screech of rusted iron, the gears shatter and slice open planar fabrics like a can opener. This functions as a plane shift spell for the Bleak Gate, except that this magic affects only you, and you arrive in the exact spot that is an analog for your current location. When you enter the Bleak Gate, the magic of the charm continues to resonate in your mind and soul for the next 10 minutes. At any point during this time, as a bonus action, you can focus on the fleeting remnant of magic and return to the plane where you used this charm, appearing in a spot analogous to your current location.
Rare versions of this charm are contingent. When you finish a short or long rest with the charm on your person, you can define or redefine a circumstance which triggers the charm. The charm breaks itself apart immediately after the circumstance is met for the first time, whether you want it to or not. This functions as the conventional activation above, and indeed, you can still break the charm normally if necessary.
