• You gain proficiency in Insight or Arcana.
• Once per long rest, you can roll two d20s for an attack roll, ability check, or saving throw, and choose which result to use after rolling.
• However, the DM may impose disadvantage on one roll per long rest to represent conflicting visions.

• You have advantage on saving throws against being charmed.
• You have disadvantage on saving throws against confusion-like effects (or DM discretion effects that distort perception).

• As a reaction, when a creature you can see within 30 ft makes an attack roll, you can impose a ±1d4 modifier to the roll (your choice).
• Uses equal to your proficiency bonus per long rest.

You know the Prestidigitation cantrip.

At higher levels:

• 3rd level: Tasha's Mind Whip once per long rest
• 5th level: Augury once per long rest

Intelligence or Charisma (choose at character creation) is your spellcasting ability.

• You can communicate telepathically with yourself, and optionally:
• Gain advantage on one Intelligence check per long rest, as your “other head” provides insight.
• But when you roll a natural 1 on an Intelligence, Wisdom, or Charisma check, you are briefly distracted (DM may impose disadvantage on your next roll).
