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.
