Hammer of Worthiness (5e Equipment)

Weapon (light hammer, warhammer, or maul), common (major) (requires attunement)

The hammer of worthiness can only be lifted by a worthy creature or the one who is attuned to it. Any other creature that attempts to lift the hammer must make a DC 30 Strength check, moving it up to 5 feet on a success.

Worthiness. While attuned to the hammer, you can spend 1 minute with it to designate a condition that qualifies a creature as "worthy". The condition can't be longer than 15 words, and can't depend on game statistics like alignment or ability scores. The condition persists once your attunement to the hammer ends, and only a worthy creature can attune to the hammer.
