Stone of the Wise (5e Equipment)
From D&D Wiki
Wondrous item, legendary (requires attunement)
The crystallization of The Great Work. This beautiful translucent dark, blood-like red gemstone is a powerful transmutation amplifier that overflows magical power. It's said to contain the souls of many people and that those who wield it are able to transcend life and death and perform miracles.
Non-equivalent Exchange. This stone counts as any material components necessary for a spell and is not consumed by casting the spell through it. You gain this benefit as long you're holding the stone, even without being attuned to it.
Transmutation Array. When you attune to a Stone of the Wise for first time, you learn up two of the following cantrips: acid splash, control flames, druidcraft, gust, magic stone, mending, message, mold earth, poison spray, prestidigitation, primal savagery, produce flame, shape water, shillelagh, spare the dying, thaumaturgy, thorn whip.
Twilight Alchemy. While attuned to this item, you can use it to make ability checks instead of a herbalism kit, a poisoner's kit or alchemist's supplies, and add your proficiency bonus to them. In adition, if you spend exactly 7 uninterrupted hours of work alone to craft items or magical items, you make 250 gp of progress towards them, but gain 1 level of exhaustion.
Elixir of Immortality. While attuned to this item, you don't age and are immune to poison and disease. In addition, you no longer need food or water.
Equivalent Exchange. While you're holding the stone, you can use an action to cast the wish spell. The stone brights until become pitch black and then it's destroyed.
