Astral Shard

You can attach the shard to a Tiny object
(such as a piece of jewelry) or detach it. 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, immediately
after casting the spell you can teleport to an unoccupied space you can see within 30 feet
of you.
