Outer Essence Shard
Source: Tasha's Cauldron of Everything
Wondrous item, rare (requires attunement by a sorcerer)
This flickering crystal holds the essence of an Outer Plane. As an action, you can attach the shard to a Tiny object (such as a weapon or a piece of jewelry) or detach it. It falls off if your attunement to it ends. You can use the shard as a spellcasting focus while you hold or wear it.
Roll a d4 and consult the Outer Essence Shards table to determine the shard's essence and property. When you use a Metamagic option on a spell while you are holding or wearing the shard, you can use that property.
