Brute. A melee weapon deals one extra die of its damage when the bugbear hits with it (included in the attack).

Heart of Hruggek. The bugbear has advantage on saving throws against being paralyzed, stunned, or put to sleep.

Surprise Attack. If the bugbear surprises a creature and hits it with an attack during the first round of combat, the target takes an extra 7 (2d6) damage from the attack.

Multiattack. The bugbear makes two melee attacks.
