Master Lewsi's Orb of Seeing

Master Lewsi's Orb of Seeing
Wizard Focus (Crystal Ball), Unique (requires attunement by a divination wizard)

A white crystal sphere, purchased by Ivan from the owner of the Thirsty Turtle Inn in Luthe Ada. This sphere appears to augment a wizards divination ability by influencing portent dice and divination spell casting.

The crystal glows blue whenever the wielder uses one of their portent dice. Once a portent dice is expended, the wielder may spend one minute in contemplative silence, concentrating on the crystal ball. During this time, the wielder makes concentration saves as if concentrating on a spell. Once this is completed, the wielder of the crystal ball regains one expended portent di.

The wielder may reroll one of their portent di while under the effect of the divination ability Third Eye (phb 116). This extends only to dice the wizard has not already expended, and can only be used once per use of the Third Eye ability.

Additionally, a divination wizard may cast any diviniation spell from their spell book that they otherwise do not have prepared. You may use this feature a number of times equal to your proficiency modifier. You automatically regain this feature after a long rest, and at the same time that you roll your initial portent dice.
