Heroic Old-School Roleplaying
Core Rules: Vessels
Vessel Statistics
- Armor Class (AC): A number representing the difficulty to hit the vessel.
- Crew: The number of creatures required for normal vessel operation.
- For every 10% below the required crew, the vessel’s speed is reduced by the same amount.
- Cargo Capacity: The maximum load that the vessel an carry.
- Damage Threshold: The amount of damage from each hit the vessel can ignore before affecting the it’s integrity (and reducing its hull points).
- Hull Points (HP): A number representing the vessel’s structural integrity. A vessel that is reduced to 0 HP is destroyed.
- Speed: The rate at which the vessel can move when fully crewed.
- Weapons: The numbers and types of weapons that the vessel can carry.
Vessel Combat
Vessels may be targeted in combat.
- To hit, attacker must roll vessel’s AC or higher.
- Any damage done to a vessel is reduced by the vessel’s Damage Threshold.
- If this reduces the damage to 0 or less, no damage is inflicted to the vessel.
Effects of Damage
Vessels that lose hull points will have their movement speeds reduced based on the amount of damage sustained.
- For every 10% hull points lost, the vessel’s speed is reduced by the same amount.
- This could be caused by ex: engine damage, water seeping into the hull, or the loss of stabilizing sails.
Destruction
When a vessel is reduced to 0 hull points:
- All mounted weaponry ceases to function, and
- The vessel loses structural integrity in 1d10 rounds (ex: sinks or breaks apart).
Repairs
Vessel damage can be repaired with successful skilled ability checks as determined by the GM.
- Damage can be partially repaired in the field, up to 50% of total sustained damage.
- Damage can be fully repaired by experienced technicians at a dock or workshop.
- A single person can repair a single hull point of damage per turn (10 minutes) spent repairing (doing no other actions).
Boarding
In order for the occupants of one vessel to board another, the vessels must be brought alongside each other.
Grappling
- If both vessels are moving, they must be held together (ex: with grappling hooks) before boarding may occur.
- If the occupants of both vessels wish to grapple and board, it occurs automatically.
- If one side does not wish to grapple, they must evade.
Once two vessels are grappled together, creatures may move freely between them.
- Creatures get -2 to attack rolls and AC during any round that they moved between vessels.
Mounted Weapons
Some vessels may have weapons mounted upon them for attack or defense, with types of damage and ranges varying by types of craft.
