Modified Hit/Damage System

A modified hit resolution system for Full Thrust I'm planning on using the
Full Thrust weapon, damage and design system for
space combat in a sci-fi RPG game I'm running. While working up cheat
sheets for the players, I decided I wanted to borrow the additional
to-hit
modifiers fortarget thrust from Battle Rider.  The trouble is, a -1 or
+1
modifier is rather a big deal on a d6 based system. But it's not quite such a
big deal for a d12, and this set me to thinking.

Here's the reuslt: Number of dice rolled by a given beam battery remains the
same. D12 are used instead of D6s. The following damage chart is used.

 1-6   = 0 damage
 7-10 = 1 damage
11-12 = 2 damage

Modifiers for Target's Screens: If the target has screens, the number of
active screens is subtracted from each die roll.

(Optional)Modifiers for Target's Thrust:
-1 to each die if the target has expended no thrust points that turn
+0 to each die if the target has expended any thrust points that turn
+1 to each die if the target has expended any thrust points that turn
and the firer finds himself in the target's aft arc.

Now, you are probably wondering how this compares to the old system:

Old System: 0 Screens: 50.0% chance of 0 damage, 33.3% chance of 1 damage,
16.6% chance of 2 damage 1 Screen: 66.6% chance of 0 damage, 16.6% chance of 1
damage, 16.6% chance of 2 damage 2 Screens: 66.6% chance of 0 damage, 33.3%
chance of 1 damage, 0% chance of 2 damage 3 Screens: 83.3% chance of 0 damage,
16.6% chance of 1 damage, 0% chance of 2 damage

New System 0 Screens: 50.0% chance of 0 damage, 33.3% chance of 1 damage,
16.6% chance of 2 damage 1 Screen: 58.3% chance of 0 damage, 33.3% chance of 1
damage, 8.3% chance of 2 damage 2 Screens: 66.6% chance of 0 damage, 33.3%
chance of 1 damage, 0% chance of 2 damage 3 Screens: 75.0% chance of 0 damage,
25.0% chance of 1 damage, 0% chance of 2 damage 4 Screens: 83.3% chance of 0
damage, 16.6% chance of 1 damage, 0% chance of 2 damage

Not too bad a fit. The four screens line is added to show the affect of 3
screens and a -1 to hit from expending no thrust points that turn.  If
you don't use the target thrust modifiers then you might want to consider
allowing ships to buy up to 4 screen systems.

Comments?

Why is not expending thrust a good thing? Surely if the ship expended no

thrust its velocity and flight path are easier to predict and so its easier to
hit
so should get a +1 modifier?

What are the modifiers trying to simluate? I don't think its deflection as it
only applies to the afct arc, but why does being in the aft arc and the ship
having thrusted give you an advantage?

Finally I've bought handfuls of D6 for FT, I don't want to buy handfuls of D12
as well, but if you already have them give it a whirl...

Whoops. Sorry bout that. The modifiers work under the following set of
assumptions:

1) Lighting off the main engines makes the ship easier to detect. If you have
no drive emissions in a given turn, it's harder to find you, and thus harder
to hit you.

2) The main engines exhaust is to the rear of the ship, so if you find
yourself behind someone who is using their main engine, finding them is much
eaiser as they are ejecting gouts of superheated plasma or some such.

Now, if your drives are reactionless force fields of some sort (like HH
impeller wedges) then the modifier for aft arcs clearly doesn't make a bit of
sense.

Does this clear things up a bit?

Yes now you have given the context it makes sense, Thanks
