There's several reports of creatures drowning or suffocating before burning to death even in 7/7 magma, is it possible that dwarves not burning in 1/7 magma is just a bug? --Syndic 17:40, 10 April 2010 (UTC)

Could be. I would have added it to the talk page first, but Ip users can't even create talk pages >.> --78.151.176.4 18:24, 10 April 2010 (UTC)

I'm aware of the reports but haven't looked into it myself yet. Add to this the reports of dwarves melting when it rains on a scorching day and it adds up to a pretty screwed up temperature system. You've got three different things that could be a factor. The components of a body have been radically overhauled, that's vastly more complex. We've got the new spatter system, also radically new, might be related, might not. And we've got the new temperatures in worldgen which are very different. I think the worldgen bit is because of a change that makes elevation influence temperature.
It all adds up to a huge poorly understood mess for now. I wasn't going to say anything about it on the main page yet because it's still wild theory that is not well understood. But I didn't feel it was worth arguing about either, so I didn't delete the note about it on the page. I did edit it slightly just so it looked better without trying to change the content of the message. -- Doctorzuber 18:42, 10 April 2010 (UTC)
What I found is that all creatures will survive being fully submerged in lava for a short time, not just magma immune ones. However, the ones that aren't magma immune will be burnt before being able to leave the square (when next to a ramp). If a non-immune creature is in 7/7 magma for more than 1 turn they will generally bleed/burn to death. --dUMBELLS 22:39, 10 April 2010 (UTC)
I confirmed this. I tapped into one of these new fangled rigidly shaped volcanos just to test this issue and verified two things. magma is pressureless as expected, and contrary to expectation dwarves do not instantly die when coming in contact with magma. My unlucky miner fled the scene quickly but was without a doubt fully immersed in 7/7 magma before doing so. He suffered no injuries.
Following this test I went ahead and flooded the whole fortress in magma verifying that magma can still kill dwarves, just not as efficiently as expected. The magma also left many objects fully submerged but unharmed which is also quite strange.Doctorzuber 16:52, 11 April 2010 (UTC)
I had some fun with a volcano, underground caves, a reptile man tribe, my animals and at last my own dwarves. I dropped my animals down into the volcano but I was somehow disappointed by seeing a living dog "diving" in lava. He fell all the about 90 z.levels down, without even getting hurt. When he landed in the magma see far deep underground, he started to burn/bleed/die. I repeated this with my dwarves and other animals. It seems, falling THROUGH lava does not hurt only standing in it. Maybe it has some other reasons, but all my dwarves/animals reached the bottom magmasea unharmed.--Niggy 16:45, 16 April 2010 (UTC)

Magma Sea

There is a new line in world gen for Magma Layer YES/NO which would probably turn off the magma sea feature if desired. Doctorzuber 18:50, 10 April 2010 (UTC)

Pipes and pools

Going by in-game terminology, there are no more magma pipes - there are only "magma pools" (which are obsidian-lined, extend up from the magma sea, and presumably refill just like 40d magma pipes) and volcanoes (which are likely just "magma pools" that extend all the way to the surface). In Adventurer mode, I encountered magma that extended all the way to the upper cavern layer (but no further), and the game reported that I had discovered a magma pool; upon jumping into it (stepping into the open space above it - stepping down into the magma left me "swimming" at the top of it unable to move at all), I plummeted straight to the magma sea ("discovering" it in the process) and slowly melted. --Quietust 20:07, 20 April 2010 (UTC)

Praise the plummeters! I've only played with two maps - one had a volcano(?) that was visible on the main embark map, and the other had nuthin'. If we need to redefine/delete some terms, then that's what we need to do - if there are no "pipes" in game, then we stick with "pools" and never refer to pipes again.
(For reference to new players, in 40d "magma pipes" and "magma pools" could both be hidden and required revealing by mining - pipes would refill slowly if any magma were removed (by channeling/pumping), but pools contained a fixed amount only. These may need redefining according to the 0.31 usage.)--Albedo 20:40, 20 April 2010 (UTC)
Keep in mind that pipes and pools as seen in 40d are hidden features again. So it's hard to casually say they just don't exist. Without the finder they're difficult to locate but for now I am still assuming they do still exist. It's very possible they've changed with the new underground stuff, but it's hard to say right away. Give it time. Doctorzuber 17:51, 21 April 2010 (UTC)
I inspected a few maps with reveal out of boredom and noticed an oddity. I found what looks like a lava pipe (the usual shapeless large semi-circular area), but it had no lava. It only extended through about 5 z-levels and never touched lava. I can also confirm that I've seen pipes (pools?) that extend down to the sea as described. I spotted this in reveal and didn't get the message for finding it so I can't say on your pipe/pool thing. --Doctorzuber 20:06, 28 April 2010 (UTC)
Well, the game refers to them as 'pools'. So we should go with that until we have more information. --Tarran 20:23, 28 April 2010 (UTC)

Infinite Magma Sources

Is there any way to guarantee that you will get a magma pipe on embark? Making large magma systems or obsidian factories seems like it would be more difficult when you have to work with finite amounts of magma. --129.252.122.38 15:10, 21 April 2010 (UTC)

You're guaranteed a magma sea at embark unless you turn that off in the world gen settings. As for finding a pipe just look for an actual volcano. You can adjust the world gen settings to be rich in volcanos if you so desire. Set elevation 200:400:3600:3600 and a high number of volcanos in worldgen if that is what you want. Of course, at present a volcano has no variance of shape whatsoever, and magma behaves a bit oddly. But if that's what you want it's easy enough to get. Doctorzuber 17:41, 21 April 2010 (UTC)

Magma Temperature

What Temperature Is Magma In This Version? I Suspect It Is 12,000° Urist But Need Confirmation Before Editing The Article. Should This Go Into Magma Properties Or The Top Of The Article? --80.137.113.241 15:33, 8 May 2010 (UTC)

Possibly, But as you say, it's not confirmed yet. And there's been some confusion on the subject over in the bug tracker. Apparently the list of magma-safe materials has undergone some pretty dramatic changes, and brought in a bug or two to confuse things. --Doctorzuber 16:30, 8 May 2010 (UTC)
Magma's temperature is still 12000, as verified using dfprobe or dtil (with a sufficiently updated memory.ini). Also, Capitalizing Every Single Word You Type Makes You Look Rather Peculiar. --Quietust 16:39, 8 May 2010 (UTC)
Thank you, I was waiting on confirmation before adding a note about temperature here since I saw there was some confusion on the subject. I updated it now. --Doctorzuber 21:21, 8 May 2010 (UTC)

Magma buildings

Does anybody have any idea what how the game decides when 'magma' has been discovered? I am 'playing' with magma spawning utilities and i cannae get ma magma smelters! Shabang50 20:14, 16 May 2010 (UTC)

As soon as you discover the magma sea, or a magma pool. If you embark on a volcano you are allowed to build them immediately. --Tarran 00:34, 17 May 2010 (UTC)


Volcano eruption

I just settled up on island in the middle of the sea with a visible volcano mountain, in a scorching climate. A few minutes after beginning to build my fortress it started raining. When the rain was about to stop I see a huge red thing, LAVA EVERYWHERE! The volcano seems to have erupted and lava is burning down the mountain and I expect my newly construct fortress to be drowned soon. I don't know if the rain is the cause of this lava flooding or if it is just an eruption. It may just have been a coincidence. Or the water may have been so hot, due to the scorching climate and changed into lava. Lava flood can be a logical explantation to the formation of the island. Here is a video – --ToWT comment by 90.49.12.172

Rain started to fall again... and it seem that is it the source of this magma overflow. Tiles are filled up to seven one level upper the volcano. Here is a video again. unsigned comment by 90.49.12.172
It would be rather nasty if the "magma flow" tiles at the bottom of the magma sea were behaving the same as murky pools and allowing rainwater to accumulate (as magma)... --Quietust 20:19, 25 May 2010 (UTC)
It don't seem to be behave the same because I have never seen a murky pool overflow. There it seem that magma is erupting from the upper level from what I have identified, when thinking about how to build my fortress, as the "top" of the volcano. Since the first flood there has been magma on that level. After taking a better look now that my fortress should be safe, the rain is no responsible for the phenomenon. Lava comes out of the volcano even when it is not raining. Now what I would like to know is why is magma flooding out. Any suggestions? – --ToWT comment by 90.49.12.172
In that case, the bug is probably that the "magma pool" (read: volcano) is refilling past the top - if it's not already in the bug tracker, it might be wise to add it (and upload a savegame so others can reproduce it). Also, please sign your comments (by typing --~~~~). --Quietust 21:38, 25 May 2010 (UTC)
But is that really a bug? I mean, there are continuous lava flooding volcano in the real world. --90.49.12.172 21:45, 25 May 2010 (UTC)ToWT
Maybe the Rain is forming obsidian that is dropping to the bottom of the magma sea and causing magma to displace out of the volcano --Ghosteh 12:51, 27 June 2010 (UTC)
If obsidian forms and collapses (from rain) there should be warning messages about it. Also collapsing obsidian will not typically displace anything, it will instead hit the floor and shatter back into raw ore which doesn't displace fluids.--Doctorzuber 16:46, 27 June 2010 (UTC)
