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 two attacks, either with its glaive or its longbow, and uses its Incite Rampage if it can.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 5 (1d4 + 3) piercing damage.
Glaive. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 8 (1d10 + 3) slashing damage.
Longbow. Ranged Weapon Attack: +4 to hit, range 150/600 ft., one target. Hit: 6 (1d8 + 2) piercing damage.
Incite Rampage (Recharge 5-6). One creature the gnoll can see within 30 feet of it can use its reaction to make a melee attack if it can hear the gnoll and has the Rampage trait.
