Antler from the Faerie King Oberon

This warm crystal glints with the sunset colors of the Fae sky and evokes whispers emotional memory. 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.

This shard can be used once per day (resets at the next dawn) as focus for a single spell. This focus makes that spell do the maximum amount of damage possible or if a noncombat spell then an automatic d20. Once the shard is used the player must roll a d100 to determine the wild magic surge that comes as a consequence of using the shard.
