Airship

Gondola

Armor Class 13

Hit Points 250 (damage threshold 10)

Control: Propeller

Armor Class 15

Hit Points 100

The propeller is a steel walled compartment that holds the magically bound air elemental. The elemental power the aft propeller. Without the elemental to propel it, the ship can't push itself across ice or snow and, if aloft, it moves in accordance with the prevailing wind. Opening the steel hatch bolted shut from the outside frees the elemental.

Two horizontal-sliding iron levers are set in the adjacent wall inside the airship. One lever controls Thrust the other controls Direction. Moving the Thrust level to the left opens valves that allow wind from the elemental to spin the propeller. Moving the lever to the right closes the valves, and the propeller stops turning. Moving the Direction lever to the left or right causes the propeller to pivot in that direction, allowing the ship to turn while the propeller is operating. When the Direction lever is centered, the propeller moves the vessel straight ahead.

Movement: Balloon

Armor Class 15

Hit Points 100; if the balloon drops to 0 hit points, it bursts, and the ship loses the ability to fly.

Speed (air) 15 ft.; 5 ft. while travelling into the wind; 25 ft. while travelling with the wind.

Furnace In the center of the upper deck is a 10-foot-tall cylindrical furnace with a fire elemental magically trapped inside it. A narrow hatch in the front of the furnace has a small grill through which the elemental can be seen. Opening the hatch doesn't release the elemental, but destroying it does. Casting dispel magic (DC 19) on it or breaking it (AC 15, 30 hit points, a damage threshold of 10, and immunity to fire, poison, and psychic damage) releases the elemental.

An iron wheel on the starboard side of the furnace open and closes a bronze valve at the top of the cylinder, which has the effect of increasing or reducing the size of the fire spilling out of the furnace. the more heat that is allowed to fill the balloon, the higher the ship can rise. If the furnace is destroyed or the elemental released from within it, the air inside the balloon cools, causing the airship to descend at a rate of 10 feet per round.

Movement: Sleight Runners

Armor Class 12

Hit Points 50

Speed 15 ft.

Weapon: Ballista

Armor Class 15

Hit Points 50

Ranged Weapon Attack:  +6 to hit, range 120/480 ft., one target. Hit: 16 (3d10) piercing damage.

Weapon: Harpoon Gun

Armor Class 15

Hit Points 50

Ranged Weapon Attack: +6 to hit, range 120/480 ft., one target. Hit: 16 (3d10) piercing damage.

In addition to dealing the damage on hit the harpoon also impales the target. While impaled, the target can't take any actions on its turn other than trying to free itself from the harpoon, which requires a successful DC 15 Strength check. If the check succeeds, the target takes 5 (1d10) piercing damage as the harpoon is pulled free and is no longer impaled. If a harpoon is attached to the gun by a rope, a creature impaled on that harpoon can't move farther away from the gun or increase its altitude until it frees itself. A creature within reach of the gun's winch can use its action to reel in a harpooned creature, pulling it up to 20 feet closer to the gun.

On its turn, the airship can take 3 actions, choosing from the options below. It can take only 1 action if it has only two crew. It can't take these actions if it has no crew.

Fire Ballista. The airship can fire its ballista. The ballista has a 90-degree arc of fire (side to side, and up and down).

Harpoon Gun. The airship can fire its spring-loaded harpoon gun. The harpoon gun comes with a winch, a 500-foot coil of hempen rope and has a 90-degree arc of fire (side to side, and up and down). Although it fires harpoons instead of bolts, the gun is considered a ballista. Tying a rope to the harpoon takes an action.

Move. The airship can use its propeller to move with its balloon or sleigh runners.
