Re: That wonderful stuff: Lava
How does that stop the fumes from poisoning and roasting you?

Re: That wonderful stuff: Lava
Maybe it's just me, but 3d doesn't seem like nearly enough for molten lava. Lead has a melting point of about 330°C. Freshly erupted lava can get up to 1,200°C. I'd eyeball it as at least 10d per second of exposure assuming you were getting hit by splash and splatter. For complete immersion, I'd just handwave as instant death (with kudos to the earlier posted PDF :D) unless the character had fire DR at some irrationally high level or another magical way of weaseling out of it.

Re: That wonderful stuff: Lava
This conversation turned out to be far more amusing than I originally thought it was going to.
So, at this point, I'm looking at splash/contact as doing 8d+2 per second, and immersion as doing at least 600% damage (however many hit points you have, you take at least 6 times that much). Anyone know anything about the toxic fumes though? I mean, discovery channel specials show the scientists studying volcanoes wearing those crazy suits with air supplies. There must be danger just from the fumes right? That PDF really is fantastic. |

Re: That wonderful stuff: Lava
Well, it's not like lava has a fixed temperature. So there's a wide range. I will be assigning numbers, on the principle that guessed numbers are better than none :J
Fresh from the interior, I'd guess 32d/sec burn damage from immersion. At these temperatures, even convection can't keep up, and you're probably looking at about 24d/sec burn damage from contact or being next to it. Maybe -1d/sec per hex, in open air. A lava flow, hot enough to still be flowing but with a crust of solid black rock, I'd guess 10d/sec from immersion, 8d/sec from contact, 5d/sec from being next to it. Also -1d/sec per hex, so you can stand a few yards away and not take damage. This is also a reasonable level for traps that pipe magma around. (Hail the retracting bauxite bridge!) For lava that's cooled enough to stop in place, I'd guess 3d/sec from immersion. A large chunk of it, however, may have a more-liquid(i.e. hotter) core. Similarly the surface is cooler, maybe 1d/sec from contact. This is only marginally hotter than fire, so you might take 1/sec within 1 hex, but the air temperature is likely to be within mere heat rules. If it's cooled enough that a complete shell of black rock has formed, the surface is at fire temperatures. On the other end of the scale, boiling magma is going to be significantly hotter; this guess is even sketchier, but say 100d/sec for immersion, 75d/sec for contact or in adjacent hexes, -1d/sec per hex away. However, mere liquid magma with gases boiling through it falls into the first category. All of this assumes open air. In a confined area, air temperature will rise until it burns like contact. Or if it's in a tube that's open at both ends, you can get a real good wind howling through there. This may merely require DX rolls to not fall over, but when the convection maxes out, it may be best to hug the ground and use the climbing rules. Now, the above only considers the direct heat-transfer damage. There's also the "hot weather" and fumes. Heat(B434) caps out at fire temperatures, so just use that cap as-is. In open air, the fumes from a stable flow will be at the level of Mildly Toxic(S78) or "pollutants"(B429). If it's in the process of erupting, the air nearby will be more like Highly Toxic or "lethal gases". In a confined area, a stable flow can also build up to this level, or beyond if it's been sealed for a while.

Re: That wonderful stuff: Lava
I'm pretty sure that in a campaign where the GM allows you to walk across the lava by merit of your Kung-Fu training, issues like poison fumes and the wafting heat will be pretty much brushed aside :-P.
