Guys I had so much fun coming up with the first list of dumb D&D items that I just had to make some more:
The Cloak of Water Resistance: upon donning this shimmering blue cloak, the user gains the ability to repel all water. Water-based attacks (tidal waves, watery spheres, etc.) simply part around them, and they can walk on water at half their regular speed. However, they will also experience crippling hydrophobia, and struggle to willingly get near any lakes, oceans, rivers, ponds, etc.
Child’s Wonder: this item is a small wooden airship, intricately carved and fully capable of flight for one hour per day at flying speed of 120ft. However, it can only fit creatures of the size category “tiny” and smaller. It leaves a cloud of rainbow glitter in its trail.
The Ring of Warning: this ring gives off a magical aura and occasionally glows. Only an Identify spell will reveal that it just gets brighter in the presence of strong sunlight. Apply sunscreen when UV radiation is high.
The Stick of Returning: this small twig wants to go back to the tree from which it came. As players get closer and closer to its destination, more and more leaves will grow from its tip. This item can also cast the cantrip Druidcraft once per day, which increases in strength as it nears its tree.
The Necromancer’s Compass: a shriveled, ancient thumb of indeterminate origin. When placed on a flat surface, it will point north. Also, ew.
Rose-tinted Glasses: a pair of wire spectacles with pink lenses. Upon wearing these glasses the user gains a +5 to charisma checks for cheering people up. They also suffer a -5 to wisdom checks, and feel incredibly optimistic about the world.
The Wooden Duck: it looks like a duck. It’s painted like a duck. And soon it’ll quack like a duck too. This object transforms into a living, breathing bird when placed into a body of water. It can be commanded to swim, dive, or generally whatever it is that ducks do in lakes. Responds to the name “Lionel.”
