Magic Items

Flavor:
This maul’s head is sculpted to resemble the first storm giant’s ruler, King Hekaton. The edge wears and scars marking the weapon speaks about the brutal battle its previous owner has gone through with the other giants. Whenever a giant comes within range of its wielder, the maul glows and lets out sparks of electricity.

While holding this rod, you can take a Magic action to activate it. The rod then instantly transports you and up to 199 other willing creatures you can see to a demiplane. You choose the form the demiplane takes. It could be a tranquil garden, a cheery tavern, an immense palace, a tropical island, a fantastic carnival, or whatever else you can imagine. Regardless of its nature, the demiplane contains enough water and food to sustain its visitors, and the demiplane’s environment can’t harm its occupants. Everything else that can be interacted with there can exist only there. For example, a flower picked from a garden there disappears if it is taken outside the demiplane.

For each hour spent in the demiplane, a visitor regains Hit Points as if it had spent 1 Hit Point Die. Also, creatures don’t age while there, although time passes normally. Visitors can remain there for up to 200 days divided by the number of creatures present (round down).
When the time runs out or you take a Magic action to end the effect, all visitors reappear in the location they occupied when you activated the rod or an unoccupied space nearest that location. Once used, this property can’t be used again until 10 days have passed.
This rod has the Wicked property: When the bearer is presented with an opportunity to act in a selfish or malevolent way, the item heightens the bearer's urge to do so.
Flavor Text: "This blue-green staff set with a red tourmaline is a treasure from Oghma, the Lord of Knowledge. Bearers of this rod seem to always feel a heightened sense of self-interest while holding this item."

Wondrous Item, common
This copper amulet contains tiny interlocking gears and is powered by magic from Mechanus, a plane of clockwork predictability. Faint ticking and whirring noises emanate from within. When you make an attack roll while wearing the amulet, you can forgo rolling the d20 to get a 10 on the die. Once used, this property can't be used again until the next dawn.
Flavor Text: "This amulet has the Language property: The bearer can speak and understand Modron while the item is on the bearer's person."

Wondrous Item, legendary (requires attunement by a wizard)

Flavor
The first book of Mystryl emits a divine green glow when in use. The symbol of Mystryl is carved into the front. Three of such books exist and the full extent of their capabilities are unknown. You may request the book to perform a task for you (at DM’s discretion), however the book may or may not accept your request. If it does, a heavy price is expected.

Weapon (glaive), legendary (requires attunement by a Paladin)

Flavor:
The blade of this glaive is forged with obsidian steel black as night. Whenever it senses an undead, it glows a night blue light as if urging it's wielding to seek out such a creature, slay it, and offer its soul to Shar.

Hidden Message. While holding the stone, you can telepathically command it to replay the movie you starred in.

Flavor Text: A massive quartz gem, polished to a sheen. It came with a box full of ephemera and ads for upcoming releases.

Key. This medal can also be used to access the VIP room at the Helm and Cloak in Baldur’s Gate without needing an invite.

Flavor Text: "A lapis-studded medal wreathed with a blue rosette. It’s a tad tacky, but the free booze from the VIP room is worth it."

Weapon (scimitar), legendary (requires attunement)

You gain a +3 bonus to attack rolls and damage rolls made with this magic weapon.

The first time you attack with the weapon on each of your turns, you can transfer some or all of the weapon’s bonus to your Armor Class. For example, you could reduce the bonus to your attack rolls and damage rolls to +1 and gain a +2 bonus to Armor Class. The adjusted bonuses remain in effect until the start of your next turn, although you must hold the weapon to gain a bonus to AC from it.

Flavor: This chakram is forged in pair with the malic, sorrow, hatred, and despair of Shar all poured into its forging process. It is coated with a layer of shadow weave then folded and sharpened to an unimaginable extent. Every arc it does, every swing it takes, traces of stars can be seen in its trail. This chakram appears to be a non-sentient weapon. Only the Left Chakram of Shar knew what had happened to her sister.
