Ring

Uncommon

Story and appearance

This black onyx ring is etched with six distinct runes around its band, each one pulsing with potential energy when activated. Its origins are murky—acquired at an illegal auction by a resourceful thief with a smattering of arcane knowledge (an Arcane Trickster)—and its magic is as unpredictable as a roll of the dice when used by people with lesser knowladge about runes and magic.

Rune Activation

As a bonus action, you may activate the ring by focusing on it and reciting the phrase inscribed on its inner surface: "Unleash thy power."

Controlled Activation:
If you are at least 3rd level and have a familiarity with runes (via the Rune Carver background, the Rune Shaper feat, or access to 2nd-level spell slots), you may choose which rune to activate by speaking its name at the end of the incantation.
Random Activation:
If you lack such proficiency, roll a d6 to determine which rune activates (1–6 corresponding to the runes below).
Once activated twice in a day, the ring cannot be used again until the next dawn.
