Drifting Sigh (Patreon)

Staff, varies (requires attunement)

Within this staff lies the cloudy skies, lingering signs of the Heavenly Dragon; drifting and elusive. When this magic item absorbs energy from a dragon’s hoard or its wielder achieves great deeds, it increases in rarity and gains new properties in addition to those of its previous rarities. The DC of any of the properties of this weapon is equal to 8 + your Intelligence modifier + your proficiency bonus.

Uncommon.  While holding this staff you can move through the space of another creature, and it doesn't count as difficult terrain. You cannot end your turn in another creature's space.

Rare. This staff has a number of charges equal to your Intelligence modifier and regains all charges after a long rest.

While holding this staff you can cast one of the following spells by expending the necessary number of charges: Fog Cloud (1 charge), Misty Step (2 charges), Mirror Image (2 charges), Gaseous Form (2 charges).

Very Rare. Whenever you cast a spell using this staff as a spellcasting focus, the next attack made against you until the end of your next turn is made with disadvantage.

Legendary. Creatures of your choice have disadvantage on saving throws to maintain concentration on spells and abilities affecting you.

The spells you can cast through this staff are updated as follows: Fog Cloud (at will), Misty Step (1 charge), Mirror Image (1 charge), Gaseous Form (1 charge), Freedom of Movement (2 charges), Guards and Wards (3 charges).

Clouds. Lazily soaring through the skies as though bound to nothing at all but their own inscrutable whims. Only a being just as enigmatic can truly grasp how to take advantage of the Heavenly Dragon's aimless energies, supporting their allies from afar as their enemies struggle to take hold of their impossibly shifting form. Remain untethered, for your enemies shall struggle in your stead.
