I had an idea of adding piracy elements to a campaign of standard fantasy, and I came to think of the artillery pirates usually might have on their ships. Here are a few, and I could use some help with transcribing them so that they would make sense with minimal effort and be mostly in line with the rest of the language in 5th edition.
Ballista:
Size: Large
Actions: 3 actions to prepare the shot, 1 action to aim, 1 action to fire.
Area of effect: 5 ft x 200 ft. line
Damage: 8d6 (average 28) piercing damage (Dex save to avoid)
Siege Weapon Drawback: ?
Cannon:
Size: Large or Medium?
Actions: 3 actions to prepare the shot, 1 action to aim, 1 action to fire.
Area of effect: 5 ft x 200 ft. line
Damage: 14d6 (average 49) bludgeoning damage (Dex save to avoid)
Siege Weapon Drawback: A cannon has a strong recoil, and anyone directly 5 feet behind the cannon at the time of firing must make a Dexterity saving throw or take 4d6 bludgeoning damage and be knocked prone.
Catapult:
Size: Huge
Actions: 4 actions to prepare the shot, 2 actions to aim, 1 action to fire.
Area of Effect: A point of your choice within 200 ft. range
Catapult Missile:
Single: 10d6 (average 35) bludgeoning damage in a 20 ft. radius sphere (Dex save half)
Mortar: 14d4 (average 35) bludgeoning damage in a 30 ft. radius sphere (Dex save half)
Siege Weapon Drawback: Catapult is inaccurate weapon and the chosen point of origin has a margin of error of 3d10 feet minus your intelligence modifier (rounded down, minimum 0) in random direction.
Trebuchet:
Size: Huge
Actions: 6 actions to prepare the shot, 2 actions to aim, 1 action to fire.
Area of Effect: A point of your choice within 300 ft. range
Trebuchet Missile:
Single: 14d6 (average 49) bludgeoning damage in a 20 ft. radius sphere (Dex save half)
Mortar: 20d4 (average 50) bludgeoning damage in a 30 ft. radius sphere (Dex save half)
Siege Weapon Drawback: A trebuchet is inaccurate weapon and the chosen point of origin has a margin of error of 2d10 feet minus your intelligence modifier (rounded down, minimum 0) in random direction.
When attacking with a Siege Weapon against a very large target, such as a ship or a creature of at least huge size, you make an attack roll against it with a bonus equal to your Proficiency Bonus + your Intelligence modifier. You make the attack roll only once, and compare the result against all valid targets within the area of one missile.
All other targets within the same area are subject to a saving throw DC equal to 8 + Proficiency Bonus + your Intelligence modifier. If the saving throw fails, the targets are affected by the missile as normal.
