Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn\xe2\x80\x99t transformed. It reverts to its true form if it dies. \n'b'  Ambusher : The doppelganger has advantage on attack rolls against any creature it has surprised. \n'b'  Surprise Attack : If the doppelganger 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. \n'b'  Actions \n'b'   Multiattack : The doppelganger makes two melee attacks. \n'b'  Slam :  Melee Weapon Attack : +6 to hit, reach 5 ft., one target.  Hit : 7 (1d6 + 4) bludgeoning damage. \n'b'  Read Thoughts : The doppelganger 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 doppelganger can continue reading its thoughts, as long as the doppelganger\xe2\x80\x99s concentration isn\xe2\x80\x99t broken (as if concentrating on a spell). While reading the target\xe2\x80\x99s mind, the doppelganger has advantage on  Wisdom  (Insight) and  Charisma  (Deception, Intimidation, and  Persuasion ) checks against the target. \n'b'  About \n'b' This grayish  humanoid  creature seems almost unfinished, with a narrow head, gaunt limbs, and a sinister, noseless face.'
