Cosmololocon

Magical Item, artifact, requires attunement by an Artificer, Bard, Sorcerer, Warlock, or Wizard, Legendary

This item is a sentient concentration of raw magical energy about the size of a grapefruit. It permanently casts a warm, reddish-pink glow that radiates through most clothing or similar medium and vibrates softly while not being held. In theory, a skilled artificer could install it onto a necklace, ring, gauntlet, or casting focus. It was created by Werb as his “ultimate magic item” to entice the spellcasters of the universe with wielding it. To attune to this item, your character has to tell it a joke that will make it laugh. If you succeed, the orb lets you attune to it in whatever way is most convenient.

While attuned to the orb, you gain the following properties:

• Your Charisma ability score increases by 4, to a maximum of 24.
• You gain a +2 bonus to your spell save DC and spell attack modifier.
• You gain a flying speed equal to your base walking speed, and you are no longer affected by difficult terrain while flying.
• If you have at least 1 hit point, you regain 1d10 hit points at the start of each of your turns.
• You gain Truesight out to 30 feet.
• The Cosmololocon contains 12 charges, and it regains 1d6+6 charges each day at high noon. You can expend charges to cast the following spells, requiring only verbal or somatic components when necessary: Simulacrum (3 charges), Demiplane (3 charges), Time Stop (6 charges), True Polymorph (6 charges), and Wish (12 charges).
• Once per long rest, you can use a bonus action to expend 6 charges and instantly refresh all of your spell slots back to full.
• Your voice magically echoes with a deep, loud reverberation in any room or environment.

Dualcast. If you are attuned to this item and use an action to cast a spell, you can choose to cast any two spells during your action instead of only one (except for Time Stop and/or Wish). The spells do not have to target the same creature, and you can specify for the spells to occur one after the other or simultaneously.

Fly of Despair. If you are attuned to the orb, you can expend 2 charges to attempt to banish one creature you can see within 60 feet of you to the Fly of Despair. That creature has to succeed on a Charisma saving throw or be instantly teleported to the demiplane, where they remain for 1 minute, falling through a ravenous void showcasing all of their deepest inner fears. An affected creature exits the Fly of Despair Prone and Frightened for 1 minute. An affected creature can make a Wisdom saving throw at the end of each of their turns, ending the effect on a success.

Siphon Mana. You can use an action to make eye contact with one creature you can see. That creature has to succeed on a Charisma saving throw or take 1d6 Psychic damage, or half as much on a success, and they become immune to this effect for 24 hours. You instantly gain a number of charges equal to the Psychic damage done by this move.

Sentience. The Cosmololocon has the following ability scores: Intelligence 14, Wisdom 16, and Charisma 20. Its’ personality and alignment are up to the DM.
