Brave. The Gnoll War Leader has advantage on saving throws against being frightened
Brute. A melee weapon deals one extra die of its damage when the gladiator hits with it (included in the attack).
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 War Leader makes two attacks, either with its pike or its longbow, and use its Incite Rampage if it can.
Pike. Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit: 16 (2d10 + 5) piercing damage
Longbow. Ranged Weapon Attack: +5 to hit, range 150/600 ft., one target. Hit: 13 (2d8 + 4) 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.
Parry. The gladiator adds 3 to its AC against one melee attack that would hit it. To do so, the gladiator must see the attacker and be wielding a melee weapon.
