Cloning. The Identity Thief conjures another Identity Thief within 120 ft. of itself (using this stat block) that has its own Initiative. On its turn, it is controlled by the Identity Thief that summoned it, and lasts until it takes a single point of damage, at which point it vanishes, dissipating into nothingness.

Devour Thoughts. DC 27 Intelligence Saving Throw: One target that is Grappled by the Identity Thief. Fail: 77 Psychic damage and the target's thoughts are devoured by the Identity Thief.

The Identity Thief then regains Hit Points equal to the damage dealt.

Illusory Duplicates. Trigger: Another creature deals damage to the Identity Thief. Response: The Identity Thief chooses 3 unoccupied spaces within 120 ft., conjuring spectral illusions that are identical to itself before receiving the Invisible condition. These illusions take their turn immediately after the Identity Thief and have 26 Armor Class, 1 Hit Point, and uses one Mind-Snatching Pseudopod or Face-Melting Glob attack on their turn, targeting the closest creature (other than the Identity Thief). Creatures within 10 ft. of an illusion receives Disadvantage on all d20 rolls until the illusion is destroyed. Illusions are destroyed by taking damage, dispersing into nothingness.

Magic Drug Dealing. The Identity Thief chooses a target within 120 ft. and offers to trade a magic, mysterious drug for free. The Identity Thief must make a Persuasion check contested with that creature's Insight check. If the Identity Thief succeeds, than that creature takes the drug and consumes it at the start of their next turn.
