Amulet of the Inner Planes

This amulet is made of an unknown malleable alloy that when shaped a particular way matches the tuning frequency of one of the planes of existence. The seven points of the heptagram each correspond to the seven inner planes: Material, Shadowfell, Feywild, Earth, Water, Fire, and Air. To use the amulet, the attuned must fold the heptagram's point matching their preferred destination into the center and tap the amulet against a hard surface while casting the Plane Shift spell.

Notes: wearing and focusing on the amulet for one hour uninterrupted
