Tasha's Cauldron of Everything (Modified)
Wondrous Item
Uncommon Sorcerer Requires Attunement
This iridescent shard contains a single/black thread at its core, which occasionally morphs and twitches. 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. When you use a Metamagic option on a spell while you are holding or wearing the shard, you can roll on the Turmoil Surge table. If the result is a spell, it is too wild to be affected by your Metamagic, and if it normally requires concentration, it doesn't require concentration in this case; the spell lasts for its full duration. If you don't have the Wild Magic Sorcerous Origin, once this property is used to roll on the Turmoil Surge table, it can't be used again until the next dawn.
