With damage reduction, the dragon could be hit several times and still essentially be bulletproof. Or mostly bulletproof. Or not bulletproof, depending on how bullet-resistant you wanted the critter to be.

And speaking of which, it should be easier to hit a dragon then a spastic 6 year old. The dragon is the size of a barn.

What is it about you forgies and your fantasies of shooting children, btw?

Plate wasn't entirely useless against musket fire. Where to start my examples?

Cowboy movies where the guy straps a plate of sheet steel (or stove iron) under his poncho?

Hey? Real world: Waterloo, Napoleon's cavelry included... um... Chasseurs?, guys with nice chrome shiny breastplates that musket balls tended to slide right off of... Not so healthy for the horse, and they did fuck all against even small cannonballs, but there you have it.  Real world plate armor vs. Muskets. Plate armor 1, cannonballs 10, muskets? .5?

Forgie? Yur mama's a forgie.

One assumes that anyone fighting a colossal great wyrm has a magic bullet or two.

The point is that the dragon is armored better than a tank, but a pistol bullet doesn't bounce off.

I'd probably go with armor as DR if using guns. I can't think of a d20 game that includes modern weaponry by default that doesn't do that.

Acknowledged.  Consider my approach a creative decision rather than strict simulation.  Most of the people wearing platemail are goons I want the PCs to mow down in droves.

Quote from: James McMWill there be monsters?

Yes and ranged touch attacks would be very useful against them, just like ranged touch attack spells now.  *shrug*  But the primary opponents of the campaign will be enemy swashbucklers and maybe ghost pirates.

d20 Modern?

James... I don't have my book handy, but I swear to Doug that D20 Modern, the so called Official take on it still uses Armor as 'hard to hit', even with guns...and ray guns for d20 future.

Someone want to fact check this?

I double-checked against the d20 Modern SRD before making my previous post

Could be. Haven't played d20 modern since it first came out. If it does, I'd probably swipre firearms rules from it.

cross posted, I got interrupted mid-post by a phonecall, and scoped.  I'm not SRD savvy enough, I need books.

Heh.  Despite writing d20 Modern supplements, I don't own a single d20 Modern book put out by WotC.  1) The SRD is more portable and 2) I'm scared of including non-OGC stuff by accident

I'm running a campaign where the PCs are Conquistadors exploring a new continent named Arkhesh. We use the Renaissance firearms weapons with the following mods:

Guns do bashing and piercing damage
Guns are Martial Weapons
Guns take the same amount of time to load as crossbows, and Rapid Reload works for guns as well as crossbows

This makes a gun a superior weapon to a crossbow, but not to bows (especially compounds bows).

Let's turn to the wisdom of the ancients...

Optional gunpowder rules from "A Mighty Fortress":

At short range, all armor is ignored. At medium range the armor is penalized by 5. At long range the target's AC is penalized by 2.
(D20 has no formal short/medium/long classifications that I'm aware of, 2/5/7+ range increments might apply)

Additional damage: Reroll and add all 8, 10 or 12 results (i.e. the maximum die number)

Add one point of fire damage if the target is within 5 feet of the muzzle.

All of them sound rather reasonable.

Quote from: jrientsFor my next campaign my group will be doing a little number I'm calling Sky Pirates of Eberron.  We want to use some gunpowder in the game, but the Renaissance weapons rules in the DMG are falling a little flat for us.  Here are some prospects under considerations:

• Firearms are Martial Weapons instead of Exotic.
• Guns use ranged touch attacks to hit targets.
• Crossbow-oriented feats would be re-written as gun feats.  For example, Rapid Reload would make recharging your gun a swift action.

Comments?  Any other ideas?

I've pretty much always used guns in DnD. For as long as I've GMed anyway.

Rather than use the simple/martial firearm, I went with weapon groups (from UA) and counted firearms as exotic crossbows. Fighting classes (those with a +1 BAB at 1st level) pretty much always used exotic weapons, so guns were pretty common. So were spiked chains and katanas and such, so maybe that ain't for you.

Rather than go with ranged touch attack, I used an armor as DR variant (I also made the DR overcomeable, for reasons relating to the class-based defense bonus), so more damaging weapons were better at bypassing armor.

I also used about the same gun damage stats (with threat range 19-20, instead of x3... but only because I used VP/WP), but they were rear-loaders, and revolvers (same damage) were available. This justified rapid reload and allowed for TWF, rapid shot, etc. to be used with guns.

I got a link for the full rules mods for gun-heavy DnD if you're interested.

You really wouldn't want to.  They're horrid.
