Wondrous Item, Legendary (Requires Attunement by a Spellcaster)

Said to be infused with the wisdom and power of the god Skoraeus, this polished stone orb is veined with iridescent crystal that seems to glow from within. The orb is 8 inches in diameter and weighs 8 pounds, making it a palm-sized trinket for a stone giant but a more unwieldy item for a Medium creature to use.

While holding this orb, you can use it as a spellcasting focus for your spells. You also gain the following benefits:

Abundant Components. The orb has 3 charges and regains all expended charges at dawn. When you cast a spell while holding this orb, you can expend up to 3 charges to ignore the spell’s material components with a gold piece cost, up to 300 gp per charge expended.

Astute Mind. You gain a +2 bonus to any Constitution saving throw you make to maintain your concentration on a spell.

Divine Sight. You can see normally in darkness, both magical and nonmagical, to a distance of 120 feet.
