Fizban's Treasury of Dragons
Wondrous Item, Rarity Varies (Requires Attunement by a Spellcaster)
This wondrous item can be a scepter, an orb, an amulet, a crystal, or another finely crafted object. It typically incorporates imagery of dragons’ wings, claws, teeth, or scales. A Dragon-Touched Focus is a Hoard Magic Item, and when it steeps in a dragon’s hoard, it's abilities as a spell casting focus are increased.
Slumbering (Uncommon). You have advantage on initiative rolls. While you are holding the focus, it can function as a spellcasting focus for all your spells.
Stirring (Rare). The Stirring focus has the Slumbering property, and it gains an additional property determined by the family of the dragon in whose hoard it became Stirring:
Wakened (Very Rare). The Wakened focus has the Slumbering and Stirring properties, and while you are holding a Wakened focus, you can use it to cast certain spells. Once the item is used to cast a given spell, it can’t be used to cast that spell again until the next dawn. The spells are determined by the family of the dragon in whose hoard it became Wakened.
Ascendant (Legendary). The Ascendant focus has the Slumbering, Stirring, and Wakened properties. In addition, when you cast a spell of 1st level or higher while holding this focus, you can treat the spell as if it were cast using a 9th-level spell slot. Once this property is used, it can’t be used again until the next dawn.
