Hey people,

i was looking through the core book and i didnt find any rules for the damage of lava or severe corrisive rain.

does anyone know whether its in one of the expansions and if so which one?

otherwise any recommendations?

As far as I know, FFG have published no rules involving characters in lava.

Me, I personally use a cool third-party suplement: http://e23.sjgames.com/item.html?id=XRPLAVA which covers the interaction of characters and lava in detail. Don't worry about conversions, it's fully compatible with the WH40KRPG systems.

And it's FREE!

You could use the Special Weapon Quality: Corrosive. You'll find it in Only War.

The basics: The lava or lava/rain would have a Damage potential (d10, d10+5, 2d10, whatever), a Penetration value (for lava perhaps use the Pen of a melta weapon? for caustic rain maybe Pen 3 or 4?) and then there is a d5 (I think) permanent reduction to AP as a result of exposure to the Corrosive SWQ, which you could attribute to the laval/rain.

Mark of the Xenos (for Deathwatch) has a creature/creation that summons acid rain that reduces AP by one point per round it is exposed. I would think this might be the better way to go, maybe (and I say maybe) increasing it to 2 Damage per Round of exposure once there is no remaining AP. EDIT- Forget that bit about Damage; evidently acid rain eats armour but not TB.

huh... just did some research and according to the internet. lava is about the same temperature as a flamethrower.

so im thinking 1D10+4E, Corrosive, ignores armour unless enviromentally sealed, flame

anything you people think should be added?

btw thanks Brother Orpheo for the corrosive, and im not sure if you were trolling with that one Tenebrae, lol

Temperature has almost nothing to do with it.

Specific heat capacity, contact surface contact area and mass of material does.

This is why Hollywood uses gas-based flamethrowers (looks awesomme, limited danger) while militaries used liquid flame throwers. Ofcourse, molten rock is another matter entirely. And if you actually fall into it, your contact area is very large.

Yes and no.

Lava is a great many things, but I have to assume you mean active, flowing, glowing lava (closer to magma really)? Standing near it isn't too dangerous, but touching it is.

While the specific heat capacity is somewhat lower than that of water, this is deceptive in that it is given per unit of mass - and rock is heavy. You do not want to touch lava, certainly not for extended periodes.

The .pdf is somewhat overdone and tounge in cheek, obviously.

it probably would be quite close to magma as the world im using this for is a mechanicus research outpost on a extremly tectonically active mortuary world. that has tectonic upheavals in the areas away from the main safe cities every few hours.

and their traveling that area.

so if they got only caught with a bit of lava then what about the damage i said to that limb? or straight 1D10?
