Necklace of Exchange in Dungeons & Dragons 5e

Necklace of Exchange

Wondrous Item

Varies Requires Attunement

A necklace that, when worn, exchanges one type of knowledge for another. The knowledge given can be specifically chosen, but the knowledge offered in exchange is always a mystery.

Knowledge Given

The knowledge given can be proficiency in a weapon, tool, language, skill, or save, and can be changed after a long rest.

Knowledge Taken

After each long rest, the DM will roll a die. The necklace wearer won't have access to one of their proficiencies for that day. The affected knowledge is secret until the wearer tries to use it. The lost knowledge could be one of the following:

Weapons: Lost proficiency
Tools: No longer knowing how to use it
Languages: Forgetting how to speak/read them
Skill/saves you have proficiency in: Not being able to apply the bonus when making rolls
