D&D 5E CleverNickName's Laboratory: Let's Make Cantrip Magic Items

[Rainbow Scissors]

Andragogy Bokken
weapon (modified longsword), uncommon, (requires attunement)

This wooden longsword was crafted for a swordmage academy, to teach the basics of blending swordplay with spellcraft.
Andragogy Bokken has the same statistics as a longsword, except that it does bludgeoning damage instead of slashing. The damage counts as magical.

While attuned to Andragogy Bokken, a character gains the ability to cast the Sword Burst cantrip. An Eldritch Knight or Sword Mage attuned to Andragogy Bokken gains the ability to cast the Sword Burst cantrip as a bonus action.

Staff of the Ostentatious Muggle
staff, very rare, (requires attunement), cannot be attuned to someone able to cast spells higher than 1st-level spells

This staff can be wielded as a magic quarterstaff that grants +2 bonus to attack and damage rolls made with it. While holding the staff, you have +2 AC versus spell attacks; advantage on saves against harmful magical effects; and you cannot be targeted by magic missiles. While holding the staff, you also gain the ability cast the following cantrips: Druidcraft, Prestidigitation, Thaumaturgy.

If someone able to cast spells higher than 1st-level attempts to attune to the Staff of the Ostentatious Muggle, they must roll 2d12+2 and compare the total to their spellcasting attribute. If the result of the 2d12+2 roll is lower than their spellcasting attribute, they gain a level of fatigue. Otherwise, there is no effect, but they are aware that the attempt to attune has failed. In the event that someone is able to cast spells higher than 1st-level from multiple classes, the 2d12+2 roll is made multiple times.

Here's a matching set of exorcism-related items. The idea is that if all three of them are found and attuned by the same person, they would have a full suite of tools for capturing and exorcising a troublesome fey, demon or haint.

THE BELL OF ANATHEMA
Wondrous Item, rare (requires attunement by a cleric or paladin)

This heavy iron hand-bell has a long wooden handle, and is decorated with religious iconography dedicated to St. Cuthbert. It may be wielded in combat as a cold iron club +1. While attuned to this bell, you know the Toll the Dead cantrip and can cast it without components, using the bell as a focus. When cast in this manner, Fey, Fiends, and Undead have disadvantage on their save throw.

If all three Items of Anathema are attuned, you can also use this bell to cast Banishment as a ritual (only), once per day.


THE BOOK OF ANATHEMA
Wondrous Item, rare (requires attunement by a cleric or paladin)

This thick book is bound not with leather, but with hinged sheets of iron. It contains religious texts, edicts, and doctrines of St. Cuthbert dedicated to the censure and exorcism of demons. While attuned to this book, you gain a +1 bonus to your spell attack rolls and save DCs, and you know the Word of Radiance cantrip.

If all three Items of Anathema are attuned, you can also use this book to cast Magic Circle as a ritual (only), once per day.


THE CANDLE OF ANATHEMA
Wondrous Item, rare (requires attunement by a cleric or paladin)

A 4-foot tall, slender candlestick holds a 2-foot long church candle, both of which have been engraved with numerous edicts and judgments of St. Cuthbert. It may be wielded in combat as a quarterstaff +1. While attuned to this candle, you know the Sacred Flame cantrip and can cast it simply by striking the candlestick on the ground. If the candle is lit when this spell is cast, Fey, Fiends, and Undead have disadvantage on the save throw.

If all three Items of Anathema are attuned, you can use this candle to cast Forbiddance as a ritual (only), once per day.

SYLVAN SLINGSHOT
Weapon (sling), uncommon (requires attunement)

This sling is made from supple leather and braided cord, and would be completely ordinary-looking if it weren't for the faint Elvish runes embroidered on the pouch. While attuned to this sling, you know the Magic Stone cantrip and can use a Bonus Action to automatically cast it on the sling's ammunition before firing.

Thimble of the Garden Snake's Gambit
wondrous item, rare, (requires attunement)
This small copper thimble is decorated with a snake motif that makes the opening look like a small serpent's mouth, and two tiny green stones spaced so that they look like the serpent's eyes while being worn. Through a small copper hoop affixed to the thumbtip of the thimble runs a bronze serpent chain, allowing the thimble to worn as part of a necklace if so desired.

While attuned, a character may cast the Virtue cantrip by taking an action to place their thumb inside of the thimble and spend one of their hit dice, as though their spellcasting ability modifier were Constitution.

While attuned, the Thimble of the Garden Snake's Gambit also grants the 4 ki points that may be spent to cast the following spells: Speak with Animals, Animal Messenger, Beast Sense, Locate Animals or Plants, but only for snakes or serpents. Each casting costs 1 ki point, and all spent ki points are regained after a long rest. Optionally, Animals, Animal Messenger, Beast Sense, Locate Animals or Plants may be cast without using a ki point by instead casting the chosen spell as a ritual.

A monk who is attuned to the Thimble of the Garden Snake's Gambit may also use the ki points granted by the thimble to fuel other ki abilities.

Gauntlet of Donkey Punching
wondrous item, uncommon, (requires attunement)

This hardened leather glove is crafted from equine hide, with metal reinforcements affixed to the back of the hand and knuckles. Upon closer inspection, arcane runes line the spaces between the fingers. A DC 10 arcana check identifies the runes as a bawdy poem about life on a farm intertwined with a hag's curse.

While attuned, a character may cast True Strike as part of an unarmed strike against an equine creature (such as a donkey, horse, pegasus, unicorn, or mule).

While attuned, a character also has disadvantage on handle animal, persuasion, and diplomacy checks used to influence equine creatures, as well as disadvantage on checks involved in riding equine creatures.

If a rogue attuned to the Gauntlet of Donkey punching has at least one free hand, their unarmed strikes may be used to deliver sneak attacks.

Whip of Unescapable Enmity
weapon (whip), very rare, (requires attunement)

This Whip of Unescapable Enmity has a +2 enhancement bonus that applies to attack and damage rolls.
A character attuned to the whip gains the ability to cast the Thorn Whip cantrip while wielding the whip.
The whip has 4 charges which may be used for the following effects:

• Cast Compelled Duel, with the wisdom save DC based on the wielder's choice of Strength, Dexterity, or Charisma.
• Add +1d4 radiant and +1d4 necrotic damage to the damage roll of a successful attack with the whip
• Cast the Thorn Whip cantrip as a bonus action

If the whip has no charges at the beginning of a short rest, the whip gains one charge. During a long rest, the whip gains one charge. The whip can hold a maximum of 4 charges.

Bi-elemental Ring
wondrous item (ring), rare, (requires attunement)

Said to be the wedding ring from a union of two elemental nobles, this brass ring appears to have a faint cloud of steam flowing within the metal. While worn, it gives the sensation of the wearer's finger being dipped in warm water.

While attuned, the ring grants the ability to cast the cantrips Control Flames and Shape Water.
While attuned, a character wearing the ring gains resistance to fire damage and a swim speed equal to their land speed.
If an attuned character already has resistance to fire, they gain greater resistance and take only 1/4 damage (round down) damage from fire. If an attuned character already has a swim speed, they may dash as a bonus action while swimming.
