Circlet of Solomon's Wisdom

Wondrous item, legendary (requires attunement)

While wearing this circlet, your Wisdom score becomes 27. If your Wisdom is already equal to or greater than 27, the item has no effect on your Wisdom score.

As a bonus action, you can move the concentration of a spell you have already cast to the circlet, which maintains the concentration for you. This allows you to concentrate on up to two spells simultaneously. You may still need to make saving throws to maintain concentration on a spell maintained by the circlet, and if you fail to maintain concentration, the spell ends as normal. Ending a spell maintained by the circlet takes a bonus action.

Bible5e custom item. Its specific properties supplement the standard magic item rules.
