Chromatus Watch (5e Equipment)
From D&D Wiki
Wondrous Item, legendary (requires attunement)
This old, unadorned pocket watch looks mundane, but it holds massive magical potential. It is believed this watch was given to humans by a long forgotten chaotic primordial being that controlled time.
When activated, a single target that you can see must make a DC 20 wisdom saving throw. On a success, the target is immune to the being targeted for 24 hours. On a failure, you and the target creature are transported to a pocket dimension for up to one minute. You regain all spell slots as if you had finished a long rest. While you are in control of this pocket dimension you are immune to non-magical weapons and have resistance to all damage types. Once the effect is successfully used, this item may not be used again until a full year passes.
Cursed This item can transform you into a being known as a Chromatus. Each time you activate this item, and each round that you are in the pocket dimension, you must pass a DC 10 Wisdom saving throw. If failed, your soul tears and you become a Chromatus. Little is known about this transformation, but the Chromatus is said to be born from a rift in the time space continuum and a punishment for meddling in the natural laws. You become a being that is hell bent on destroying the space time continuum, heralding the return of a long forgotten chaotic primordial. A wish spell is required to return you to your original form.
