Rampage. When the gnoll reduces a creature to 0 hit points with a melee attack on its turn, the gnoll can take a bonus action to move up to half its speed and make a bite attack.
Multiattack. The gnoll makes three attacks: one with its bite and two with its shortsword.
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit:4 (1d4 + 2) piercing damage.
Shortsword. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit:5 (1d6 + 2) piercing damage.
Sudden Rush. Until the end of the turn, the gnoll's speed increases by 60 feet and it doesn't provoke opportunity attacks.
When gnolls are weakened, they seek out isolated settlements, maim and disable its inhabitants, and feed upon them as they rest and regain strength.
