Inverse Optional Damage Rule

CRMcNeill · Posted: Sat Dec 29, 2012 9:04 pm Post subject: Inverse Optional Damage Rule

So, I have wondered off and on about how to handle blast radius damage for when a large-scale energy weapon hits something near a character. I had a possible idea last night; we already have optional damage rules whereby a character can increase his damage roll based on how well he rolled on his To Hit roll. What if a vehicle mounted cannon received a bonus to hit based on how much damage he inflicts? He wouldn't inflict full damage, naturally, and there might have to be some kind of difficulty increase, as well as the necessity of the intended target being near something that can be shot and blown up.

This is really just a nascent concept that I haven't had a lot of time to flesh out, so I would really appreciate some input. I really do think there is something in there...

So like a landspeeder near the character being shot with a speeder scale blaster cannon?

Hmm, interesting.

In real life, large scale weapons would be using circular error probability calculation. Maybe it would work to use the grenade scatter chart and use the scale modifier to generate how far the shot missed by. Generating damage and blast radius is the kicker, but I'm trying to look at it from a perspective of the level of damage inflicted (i.e. energy delivered) affecting the size of the blast radius, and therefore the chance that a character standing near the blast will get caught in the blast and take damage. Certainly not full damage; maybe even simply capping damage results, so that within 2 meters, you get a max result of killed, 4 meters = max of mortally wounded, and so on.

Perhaps what needs to change is the dodge rule for dodging higher scale shots... Rather than flat out avoiding all damage on a successful dodge, it should be a successful dodge gets you knocked down one blast zone. Each additional say 7 above the gunner's to hit you succeeds on you dodge by knocks you down another blast zone.

Though since a LOT of vehicular weaponry does NOT list blast radiuses we would first off have to come up WITH a blast zone figure for them.

just taking a look through the stats on speeders (Bolded have no weaponry, All else have weaponry but NO blast radius listed);
Military Landspeeders
28. JX-09 Prisoner Transport
28. Speeder Command Vehicle
28. Trade Federation Troop Carrier
28. Storm Skimmer Patrol Sled
28. Urban Assault Speeder
29. Sevari Wind Rider
29. Armored Landspeeder
29. Flash Speeder
30. Escort Speeder
30. Transpeeder
30. Repulsorlift Sled
30. Gian Speeder
30. 008 Heavy Landspeeder
31. Swamp Speeder
31. Rebel ULAV
32. Stinger
32. Dominator
32. Intimidator
32. Imperial Troop Transport
33. Mekuun Repulsor Scout
33. Arrow-23 Tramp Shuttle
33. X10 Groundcruiser
34. Rebel Armored Freerunner
34. SpecForce Freerunner APC
34. Imperial Patrol Landspeeder
35. Chariot Command Speeder
35. Armored Repulsorlift Transport
36. SCS-19 Sentinel
36. Light Imperial Repulsortank
36. Medium Imperial Repulsortank
36. Heavy Imperial Repulsortank
37. FireHawke Heavy Repulsortank
37. Imperial Heavy Repulsortank
38. MTT
38. Heavy Tracker
39. TX-130 Fighter Tank
39. Teklos Battle Vehicle
40. Floating Fortress
40. AAT
41. Imperial Mobile Base

So out of just combat speeders we have a grand total of 38 vehicles with weaponry and NOT ONE with a weapon listed with a blast radius. EVEN the ones with concussion missiles, grenade launchers etc...

I like the idea. Missile weapons would have to be different, but maybe blaster weapons would have a blast radius based on damage?

IMO, the first step needs to be determining exactly how close the gunner's shot gets in the first place. Once that is established, we can then determine blast radius and how hard it is for the characters to avoid or minimize damage. It won't just be speeder scale, either. Characters can potentially face heavy laser cannon on walkers, strafing runs from starfighters, even turbolaser blasts from small warships, so any rule would need to be fluid enough to increase blast radius / difficulty based on the scale and damage of the weapon being fired.

That's a lot of math... (scratches head)

I'd prefer to have the scatter range based on the weapon's base blast radius value (= to the weapon's damage D rating, as described above). That way, the bigger and more damaging a weapon is, the greater the value it will potentially deviate by.

My original idea was going to be much simpler. It basically broke down to:

Greater Damage = Bigger Blast Radius = More Likely Characters Will Get Hit = Damage Roll generates bonus to To Hit roll, with corresponding drop in Strength of Hit = Dodge roll is added to Character's Strength soak, indicating character's ability to get behind cover and avoid the worst of the blast.Just haven't figured a way to work it that I like...

Good topic, I didn't have the rule for that in "my" SW RPG Smile

. However, I prefer to have things ultra simple = faster GM.

# of dice on damage (before adding dice for scale) on any energy weapon = blast radius in meters (this is only for weapon's above E-Web)

A character who is caught in the blast radius makes a Dodge check. Add any bonus for covers.

Dodge Result / Damage taken

10 / 80%
15 / 60%
20 / 40%
25 / 20%
30 / avoided

If a character cannot Dodge, he takes full damage.

Missiles have some blast radius given in various sources, so here things have to be worked out different.
