Firearms Knowledge.

The giff's mastery of its weapons enables it to ignore the loading property of any firearm.

Headfirst Charge.

If the giff moves at least 20 feet in a straight line and ends within 5 feet of a Large or smaller creature, that creature must succeed on a DC 16 Strength saving throw or take 7 (2d6) bludgeoning damage and be knocked prone.

Siege Monster.

The giff deals double damage to objects and structures.

Actions

Multiattack.

The giff makes two Greatsword or Musket attacks.

Greatsword.

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 15 (3d6 + 5) slashing damage.

Musket.

Ranged Weapon Attack: +5 to hit, range 40/120 ft., one target. Hit: 15 (2d12 + 2) piercing damage.

Thunder Bomb.

The giff lights a grapefruit-sized bomb and throws it at a point up to 60 feet away, where it explodes. Each creature within a 10-foot-radius sphere centered on that point must make a DC 15 Dexterity saving throw, taking 18 (4d8) thunder damage on a failed save, or half as much damage on a successful one. After the giff throws the bomb, roll a d6; on a roll of 4 or lower, the giff has no more bombs to throw.
