Special Traits

  • Shapechanger. The doppleganger can use its action to polymorph into a Small or Medium humanoid it has seen, or back into its true form. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.
  • Ambusher. In the first round of a combat, the doppleganger has advantage on attack rolls against any creature it has surprised.
  • Cunning Action. On each of its turns, the doppleganger can use a bonus action to take the Dash, Disengage, or Hide action.
  • Sneak Attack. Once per turn, the doppleganger deals an extra 14 (4d6) damage when it hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of the doppleganger that isn’t incapacitated and the doppleganger doesn’t have disadvantage on the attack roll.
  • Surprise Attack. If the doppleganger surprises a creature and hits it with an attack during the first round of combat, the target takes an extra 10 (3d6) damage from the attack.

Actions

  • Multiattack. The doppleganger makes two attacks with its claws or two attacks with its rapier per turn.
  • Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) slashing damage.
  • Rapier. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage.
  • Light Crossbow. Ranged Weapon Attack: +7 to hit, range 80/320 ft., one target. Hit: 8 (1d8 + 4) piercing damage.
  • Read Thoughts. The doppleganger magically reads the surface thoughts of one creature within 60 feet of it. The effect can penetrate barriers, but 3 feet of wood or dirt, 2 feet of stone, 2 inches of metal, or a thin sheet of lead blocks it. While the target is in range, the doppleganger can continue reading its thoughts, as long as the doppleganger’s concentration isn’t broken (as if concentrating on a spell). While reading the target’s mind, the doppleganger has advantage on Wisdom (Insight) and Charisma (Deception, Intimidation, and Persuasion) checks against the target.
