How much damage would these futuristic weapons deal if converted to D and D?

[TrueSpade]

so how much damage do you think the following would deal if there was somehow a way to attack someone with it?

Lightsaber slash
Plasma Beam
Anti-Tank Missile
Atomic Bomb
Anti-matter bomb
and Positron Laser

Lightsaber slash

See Brilliant Energy weapons.

Plasma Beam

Probably the same.

Anti-Tank Missile

Roll all your dice.

Atomic Bomb

All your dice * all your dice * all your dice * all your dice

Anti-matter bomb

All your dice * all your dice * all your dice * all your dice * all your dice

and Positron Laser

All your dice * all your dice

Anti-Tank Missile

Light antitank weapons have stats in D20 modern. They deal 10d6 damage. Heavy antitank weapons will do similar damage that of the 120mm HEAT gun (10d12). Damage scales with the fifth root of energy content in D&D, so powerful weapons tend to do fairly crappy damage.

Lightsaber slash

Lightsabers have stats in Star Wars d20. Just look them up.

Plasma Beam
Atomic Bomb
Anti-matter bomb
Positron Laser

None of these are things with specific damages attached to them. An antimatter weapon in particular could do anywhere between one damage and a billion squillion damage depending on how big it is.

An anti-matter bomb, would be a death effect if it touched you, considering any matter it comes into contact with would be removed from existence violently.

Not to mention the "all your dice" thing though obviously a joke, it would be far far more powerful than an atomic bomb.A similar example would be a gun compared to an atomic bomb really, maybe even a knife.

Lightsaber would probably be hard to add into the game since if it hits you whatever it hits is going to be melted/burned/removed. Although as said there ARE stats...


...that said now that I think of it... The Lightsaber would do the same damage as the plasma weapon.

There is Star Wars system out there, just so you know. It is a d20 system based on D&D rules, and it has almost all those weapons covered.
IIRC, Lightsabre is 2d8 19-20x2, small one is 2d6 19-20x2, double is 2d10 20x2 and counts as double weapon. I think only small one counts as light (for off hand penalties), though that is a bit strange.
Plasma grenade is in there too. It has damage type:heat, has Xd6 damage and DC for reflex saves which scales with quality. Anti-matter bomb and anti-matter guns would correspond to disruptor weapons in SW. And take a look at normal/thermal/sonic and other blasters to see how would you define others.

The amount of antimatter in an antimatter weapon that isn't going to blow up a continent is tiny. Unless what you're hitting is ridiculously tough (i.e., tougher than any physically reasonable matter) the annihilation damage is going to be insignificant next to all the DET damage.

This isn't actually true. While more powerful pound-for-pound, fission weapons have minimum yields, and (depending on what your containment is) antimatter weapons do not. You could make an antimatter bomb that was less powerful than a hand grenade if you wanted, while the same is not true of a fission or (fission-triggered) fusion weapon.

I think only small one counts as light (for off hand penalties), though that is a bit strange.

SWd20 is 3.0, so doesn't have 3.5's slightly more sensible weapon size system, I think? Weapons just had a size, rather than a 'size of creature this weapon is designed for' entry. Small creatures wielded shortswords like they were longswords, rather than just wielding small longswords. And in SW there's stuff about lightsabers having funky magnetic torque effects which mean they're less then trivial to wield if you don't know how, so it makes sense for smaller ones to be easier to wield.

There is also SW Saga edition which is something like 3.75 version. A lot of 3.5 stuff was implemented.

Simple answer: they'd do Megadamage.


*vs. MDC...

and Positron Laser

"Yes, Dr. Scott. A laser capable of emitting a beam of pure anti-matter."

• "Then it's not a laser."
• "Then it doesn't matter!"

 

[Samloyal23]

Wouldn't fission weapon be best simulated with a disintegration effect over a specific radius with heat and blast effects extending outward from that?
