Dragon Scale Mail (Red Scales)
Armor (scale mail), very rare (requires attunement)

Dragon scale mail is made of the scales of one kind of dragon. Sometimes dragons collect their cast-off scales and gift them to humanoids. Other times, hunters carefully skin and preserve the hide of a dead dragon. In either case, dragon scale mail is highly valued.

While wearing this armor, you gain a +1 bonus to AC, you have advantage on saving throws against the Frightful Presence and breath weapons of dragons, and you have resistance to one damage type that is determined by the kind of dragon that provided the scales (see the table).

Additionally, you can focus your senses as an action to magically discern the distance and direction to the closest dragon within 30 miles of you that is of the same type as the armor. This special action can’t be used again until the next dawn.

Wondrous item (tattoo), rarity varies (requires attunement)

Tattoo Attunement. To attune to this item, you hold the needle to your skin where you want the tattoo to appear, pressing the needle there throughout the attunement process. When the attunement is complete, the needle turns into the ink that becomes the tattoo, which appears on the skin.

If your attunement to the tattoo ends, the tattoo vanishes, and the needle reappears in your space.

Protection. While you aren't wearing armor, the tattoo grants you an Armor Class depending on the tattoo's rarity, as shown below. You can use a shield and still gain this benefit.

Rare: 15 + your Dexterity modifier (maximum of +2)

Wondrous Item, rare (requires attunement by a wizard)
The blood red orb pulses and whispers slurping tentacle noises in the bearer’s mind when it senses danger, granting +2 initiative.

This brass disc of articulated, concentric rings unfolds into an armillary sphere. As a bonus action, you can unfold it into the sphere or back into a disc. When found, it contains the following spells, which are wizard spells for you while you are attuned to it: augury, divination, find the path, foresight, locate creature, and locate object. It functions as a spellbook for you, with spells encoded on the rings.

While you are holding the archive, you can use it as a spellcasting focus for your wizard spells.
The archive has 3 charges, and it regains 1d3 expended charges daily at dawn. You can use the charges in the following ways while holding it:

If you spend 1 minute studying the archive, you can expend 1 charge to replace one of your prepared wizard spells with a different spell in the archive. The new spell must be of the divination school.

When a creature you can see within 30 feet of you makes an attack roll, an ability check, or a saving throw, you can use your reaction to expend 1 charge and force the creature to roll a d4 and apply the number rolled as a bonus or penalty (your choice) to the original roll. You can do this after you see the roll but before its effects are applied.
