Magic Items

While wearing this cloak, you have advantage on Dexterity (Stealth) checks. In an area of dim light or darkness, you can grip the edges of the cloak with both hands and use it to fly at a speed of 40 feet. If you ever fail to grip the cloak's edges while flying in this way, or if you are no longer in dim light or darkness, you lose this flying speed.
While wearing the cloak in an area of dim light or darkness, you can use your action to cast polymorph on yourself, transforming into a bat. While you are in the form of the bat, you retain your Intelligence, Wisdom,
and Charisma scores. The cloak can't be used this way again until the next dawn.
This cloak is made of hundreds of large, black feathers, and instead of transforming its wearer into a bat, this cloak allows its wearer to transform into a raven

This fearsome steel helm makes your eyes glow red while you wear it. This item can be found in Xanathar’s Guide to Everything.

This armor is obviously Githyanki in design. It is ornamented with tassels, ribbons, and bone fragments. Mithral is a light, flexible metal. If the armor normally imposes disadvantage on Dexterity (Stealth) checks or has a Strength requirement, the mithral version of the armor doesn’t. This item can be found in the Dungeon Masters Guide.

Wondrous item, uncommon (requires attunement)
While you wear these light shoes, you can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free. You have a climbing speed equal to your walking speed. However, the slippers don't allow you to move this way on a slippery surface, such as one covered by ice or oil.
These slippers are made of black silk embroidered with spider webs. Though they were taken off a drow the yuan-ti waylaid, they are not drow crafted.

The Mind Fortress is the remnants of an extradimensional location that served as the site of a ritual enacted by the alchemist Ravinan. Ravinan divided three aspects of his psyche, in an attempt to purify his soul, and collapsed this evil into a stone called the Eye of Darkness. The Mind Fortress then served as the extradimensional home for the stone until liberated by adventurers. After the stone was removed, the Mind Fortress shrank to a less-potent but still useful magical item.

The Mind Fortress functions in all ways as a ring of mind shielding. The Mind Fortress still contains two portions of Rhys’s psyche (his center for rational thought, as well as his conscience). These mental remnants do not count as an actual soul for purposes of the ring, nor do they cause the Mind Fortress to act as an intelligent item. However, a DM might choose to have these aspects of Rhys’s psyche may affect the emotional state of the wearer or interact with the wearer during a dream or trance state.

The Mind Fortress’s form is still highly mutable. The item periodically and randomly alters its appearance in slight ways. The bearer has no control over these minor alterations, which have no effect on the item’s use.
