Starship Notes
Combat is much like character combat, but starships have their own, generally translatable, rules in comparison to standard combat.
Energy damage from elemental energy sources are blocked by the starships hardness (x10 vs foot targets) and halved.
A starship only gains it's hd bonus vs foot targets.
A starship's "square" is 500 not 5 feet.
Attack bonus
Attack roll = Size bonus+ gunner attack bonus (up to maximum) + Targeting AI bonus +d20 roll
as stated vs other starships, against foot targets add 1/2 starship hit dice and multiply other statistics by x10
HP
As stated vs other starships x10 vs foot targets
AC
As stated vs other starships all stats x10 vs foot targets, +1 deflection ac 1/2 hd vs foot targets
Hardness
All starships are made of advanced materials that apply their damage reduction against most attack forms. As stated vs other starships and foot targets, x10 vs foot targets at PL 8 weaponry and above.
DCs
As stated vs other starships add 1/2 hd to DC vs foot targets
Starship actions
A starship's combat actions are slightly different than a character's but run off the same time frame, 6 seconds. A starship can make 2 movement actions and one standard action per round, or a full round action. 1 Swift action can also be made per round.
Shield rating
Like a damage reduction but much higher, (as stated for starships, x10 vs foot targets) ignores this damage first, any damage passing this threshold reduces this number by 5 (or 50) points. Shields can be recharged by spending three swift actions to restore 5 shields.
Active Shield hp
Other shield systems create a bubble of temporary health to absorb damage first this will usually regenerate at a rate of 1/50th the shields total hp/ round.
Screens
Some starships have energy screens which disrupt certain weapon types targeting them. This adds a bonus to the ac of screen to the appropriate damage type. This bonus is x10 vs foot targets
Cloaks and active stealth
Cloaks and active stealth make you effectively invisible or invisible from certain sensors but cannot be used effectively with shields, screens or active shielding in place. An enemy vessel may still learn your relative position if they notice your engine wake or ion trail but may not actively see your ship specifically.
Squares
The basic square for a starship is 500 feet, stellar squares are 5000 feet
Movement
Starships can move in three sometimes four distinct ways
-Tactical speed:
This is the movement of a starship when attempting to preform precision maneuvers, fight, or fly through treacherous terrain. The movement speed is factored in 500 foot squares.
-Stellar Speed:
This is the basic thruster speed allowing for faster though less precise travel through space. The basic stellar speed is 10x the tactical speed provided, if attempting to attack in stellar speed the ship suffers a -4 to attack rolls
- Cruising Speed:
The cruising speed of a starship is a factor of the speed of light. This is the basic travel speed between interstellar objects. Firing weapons with any precision is impossible at these speeds though you may fire upon another ship in cruising speed at a -4 penalty to attack
-hyperspace or warp etc
Some ships are equipped with worm hole generators, magical enhancements, or spatial collapse modules allowing for space to be bypassed to some degree and allowing for much faster travel or even instantaneous travel
Damage
Standard vs other starships x10 vs foot targets. Can also use tactical fire to fire narrow salvo AOE attacks and wide barrage AOE attacks as the situation calls. DCs for these attacks are stated above.
Capital ships
Dreadnoughts, Septentrions, Ghoma Carriers and other massive ships deal catastrophic damage to unarmored or foot targets dealing x100 damage.
Smaller vehicles
Tanks and other ground and air based equipment larger caliber than foot weapons but smaller that ship mounted weapons deal x5 damage and have 5x the stated hp vs foot targets.
Attacks of Opportunity and Point Defense systems
Attacks of opportunity are resolved automatically. Point defense systems will automatically fire upon incoming missiles or close in enemy vessels or targets, this can be actively controlled at the captain or Gunner's directive. Point defense systems have a range of your square and one additional square around your ship (1000 feet)
Magical Effects and Abilites
Magical Effects are generally unable to be used to boost a starships statistics being either too small or too weak to effectively improver their power and a starship is effectively considered an environment for purposes of targeting it with spells. Certain effects and abilites can be used if they affect the environment or otherwise can cover the entire area the ship occupies. A zone of silence for example could silence the entire area a ship exists in if it was small enough to fit within the zone. A gate spell can be used to teleport a starship vast distances as well. A repair spell will repair damage to a starship accordingly but will not restore systems destroyed or damaged beyond repair.
