Shapechanger. The doppelganger can use its action to polymorph into a Small or Medium humanoid it has seen, or back into its true form. Its statistics are the same in each form except its speed.
Ambusher. In the first round of combat, the doppelganger has advantage on attack rolls against any creature it has surprised.
Multiattack. The doppelganger makes two melee attacks.
Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d6+4) bludgeoning damage.
How hard a fight? Against a party of four, a single doppelganger is deadly at level 1, hard at level 2, medium at level 3 and easy at level 4, and barely a challenge from level 5. Add allies or more foes in the encounter generator.
Where you'll find it: towns and cities and dungeons.
