High Relics

In my Dungeons and Dragons story, the main plot points are these magical items called High Relics. Only Problem is, I can only think of two, where I need about 10.

Do you guys have any ideas?
Requirements: Name of the item, effect given when used, type of item (shield, belt, mask, etc.)

OMG I have the same thing for my campaign!
Mine are called legendary artifacts but here's a few…
The shield of foliage which is like a giant leaf only that It hides people behind what ever kind of plant that's in the area.
(It gives a plus 10 in your stealth or anything like stealth on their roles.)
But that's just one.

Hmm, I'm not good at coming up with items, but maybe poking around the Unearthed Arcana Reddit might give you some ideas? Below is a link to some of the content posted there:

Thanks so much! That really helps

Sounds like you had an idea similar to a D&D podcast called The Adventure Zone, except they were called the Grand Relics. You could use that as a point of inspiration. Here's a link to the wiki. Obvious [spoilers] for The Adventure Zone if you ever intend on listening to it.

I'm also creating my own set of similar relics for my campaign, and they might give you some ideas. Each one is made out of a rare metal called Oricalchum, and the more of them you have collected, the more of their powers you unlock. Each item starts with 10 charges, can hold a maximum of 15, and regains 1d6+2after a long rest (playing D&D 5e rules).

*Ironclad Bastion: Shield

• 1 Charge: Cast Shield as a Reaction
• 2 Charges: When an ally within 30ft of you is attacked, you may use your Reaction to teleport 30 feet. You must end in a space adjacent to the triggering ally.
• 4 Charges: Cast Resilient Sphere on a WIlling Ally as an Action
• 6 Charges: When targeted by a spell or AOE effect that deals non-physical damage (not bludgeoning, piercing, or slashing damage), you can spend your Reaction to absorb up to 6d8 of that damage and store it in the shield. After the shield has absorbed damage in this way, you can use an Attack to Shield Bash a target dealing 1d6 + STR MOD bludgeoning damage + absorbed damage.

*Beguiler Crown: Crown

• 1 Charge: Cast Disguise Self on self
• 2 Charges: Cast Invisibility on self
• 4 Charges: Cast Phantasmal Killer
• 6 Charges: Cast Eyebite

*Starlight Beacon: Torch-shaped Divine Focus shaped out of Electrum and Oricalcum

• 1 Charge: Cast Sanctuary
• 2 Charges: Cast Moonbeam
• 4 Charges: Cast Banishment
• 6 Charges: Cast Sunbeam

*Revelation Stone: 5-foot long oblong octahedronal red Oricalcum crystal

• 1 Charge: Cast Guiding Bolt
• 2 Charges: Cast Detect Thoughts
• 4 Charges: Cast Divination
• 6 Charges: Cast Disintegrate

The Adventure Zone is actually my top inspiration for my story, which is probably why it reminds you of it so much. And thank you for your suggestions, they're all amazing!
