Destroying blocks beneath the altar

"If the blocks beneath the altar are destroyed the altar vanishes and does not yield any items." - The Demon Altar seems to prevent any blocks from being destroyed beneath it, even if dynamite is used. Is it accurate to say it would vanish if they are destroyed when they can't be destroyed? — Preceding unsigned comment added by at 21:30, 23 May 2011 (UTC)

Doesn't seem so. Bobb1118 23:03, 23 May 2011 (UTC)
If the blocks below the altar is sand and that you break the blocks below the sand blocks, it will destroy the altar. --Cloakedboltz 22:17, 30 May 2011 (UTC)

Table Formating

Hi, could someone help with the table formating, I'm trying to add the Night's Edge recipe in there but I can't seem to make it work. --Cloakedboltz 02:14, 24 June 2011 (UTC)

Thanks to whoever did it. --Cloakedboltz 17:22, 21 July 2011 (UTC)


I've recently been exploring my world, and discovered that the Demon Altars always seem to appear at exactly the same height (specifically, "32 below" in a Medium world). Thus far, I have discovered about nine altars in my world at this exact height (in the Underground, just below the soil transition level) and none at any other levels. I haven't double-checked the height of the couple I've seen over in the Corruption yet, but I suspect they're the same. Can anyone else confirm this for other world sizes? -- Mirality 10:58, 17 July 2011 (UTC)

Yeah, I've noticed Demon Altars at a rather specific height range. I'll have to check the depth but it isn't far from +0ft and it's about the same for all 5 Demon Altars I've come across in my Small sized world. - Spinfx 11:37, 17 July 2011 (UTC)
UPDATE: The Demon Altars in my world are at +8ft. - Spinfx 14:34, 17 July 2011 (UTC)
Hmm. I wonder if that means that it's random for each world, or if it's related to the world size. However, I've also had a look near the Corruption now and found altars over there at several different heights, which suggests either that there are several different heights they can spawn at and I simply haven't come across any at those other heights outside of the Corruption yet, or that the rules near the Corruption are different. (The latter seems likely though, as we already know that the probability of appearing near the Corruption is higher.) - Mirality 01:51, 23 July 2011 (UTC)
Yeah, The Corruption seems to follow different rules. Coincidentally I've just gotten around to exploring corrupted areas and the first thing I noticed down there is that there are way too many Demon Altars. They're scattered all over the floor of the lower connecting chasm. - Spinfx 03:21, 23 July 2011 (UTC)
I checked the code and you're right. It uses the same number for all altars that aren't generated as part of the corruption.
In a related note, there seems to be a bug in the function that generates the corruption caverns. As the game is carving out the cave, there is a flag that it checks to see if it should make another altar. However, this flag is never turned off, so it keeps making more and more demon altars. --GauHelldragon 07:36, 23 July 2011 (UTC)
I don't have *that* particular issue (there are quite a few around the corruption, but they're still reasonably spaced) -- but then, I'm still using a 1.0.4 world. From what I hear, 1.0.5 changed the way that the corruption chasms were generated quite a bit. -- Mirality 11:04, 24 July 2011 (UTC)

Upcoming features

Should the 1.1 changes to this be here already? futRtrubL User futRtrubL sig icon.png 13:50, 14 October 2011 (UTC)

I don't think so. Upcoming features belong in upcoming features — articles should reflect the status quo. Besides, saying "this will be that way in that future version" is pretty much speculation. This particular update won't be out for another 1-2 months, and information confirmed in teaser trailers isn't set in stone. --Lunboks 14:46, 14 October 2011 (UTC)


I'm not sure if this is the right place to post, but I noticed in the notes there is a discrepancy about the number of ore created when more altars are destroyed. In the notes section one bullet says each round of destroying spawns more ore, while another a bit below it says that each altar decreases the amount. I may be misunderstanding what the note is saying and there is no discrepancy, but I think it then calls for clarification. — Preceding unsigned comment added by Hamree (talkcontribs) at 07:03, 15 December 2011 (UTC)

The bullets say: the total amount of ore increases, but it increases slower and slower when you destroy more and more demon altars. --Icke 18:20, 15 December 2011 (UTC)

this page

this page does not say if this spreds crouptin or if it spawns corutin enemys — Preceding unsigned comment added by at 00:07, 10 January 2012 (UTC)

Because it doesn't. The altar is just an item. Corruption/Hallow spreads via blocks. — Preceding unsigned comment added by Spinfx (talkcontribs) at 02:08, 10 January 2012 (UTC)


How can I move a daemon alter? or can I? — Preceding unsigned comment added by at 09:08, 22 January 2012 (UTC)

I'm sorry, but your spelling, grammar, and, well, everything else, is just terrible. I could hardly understand you at all. Anyway, the Demon Altar can't be moved. You can destroy it in Hardmode, but not move it. — Preceding unsigned comment added by at 15:14, 12 February 2012 (UTC)

Spawning more corruption/hollow

Does anyone know what the chances are and if it really is any random stone tile or is there any pattern or specific depth or area it seems to occur in? — Preceding unsigned comment added by at 08:15, 25 January 2012 (UTC)

The conditions are as follows:

At the time of smashing an alter roll a number between 0 and 2 inclusive.

If a 1 was not rolled (66% chance)
Pick a random stone block. The block must be at least 100 blocks from the edges of the map, lower than (rock layer + 50 blocks), and higher than (map depth - 300)
If a 0 was rolled (33% chance)
Change the stone block to ebon/crimson (chosen at world generation)
Change the stone block to a pearlstone block

Lots of Altars!

Hi, yesterday I went into a corruption chasm and blew up ebonstone until i reached the tunnel connecting the chasms. That tunnel was around 0 ft, and i was surprised of the outcome of the location of that tunnel: sin ce it was in perfect demon altar spawning territory, i found 10-25 altars! Once i get in hardmode, there will be lots of ores! Anyway, has this happened to anyone else? -Rampardos18 22:13, 8 June 2012 (UTC)

Proximity of altars and maximum amounts

The page stated, "Sometimes up to 7 can spawn on screen if you are very lucky but its very rare." I changed this to 8 and uploaded a screenshot based on my own experience. Let me know if you find more than that though, I'd be interested to see it! :) --Monkey 05 06 01:32, 10 August 2012 (UTC)

Corruption Spread

Do it spread corruption? I doubt it but just to make sure.. FunAlways (talk) 14:51, 21 March 2014 (UTC)

It does not. Amdethe (talk) 17:33, 21 March 2014 (UTC)

New ore without breaking any demon altars

as it states in the title i havent broken any demon altars and the new ore spawned while clearing corruption. wall of flesh is done 05:44, 11 August 2015 (UTC)

Spawning ore automatically

If an altar is destroyed by sand/spike purification pre-hardmode, does the world automatically spawn a hardmode ore once Wall of Flesh has been defeated? EyeofToothy (talk) 13:17, 19 August 2015 (UTC)

I found the rarest spawn ever!!

i just found 10 altars on the floor of the ocean! idk how to upload photos but ill send a link (Snapped with Lightshot) i was shocked! i was scavenging for the stuff in the chests but it was a bloody surprise... its so cool that i found the rarest spawn and tell me how do you like it! :D — Preceding unsigned comment added by Rapolis (talkcontribs) at 14:00, 6 April 2016 (UTC)

Sorry, the image is too dark... I can't tell what I'm looking at. Do you have any ichor torches to light the place up? --Ferretwings (talk) 14:34, 6 April 2016 (UTC)

Purification removes altars?

I had two altars spawned stacked ontop of each other, and when I purified the blocks beneath them it seemed to destroy the stack. Is purifying blocks known to destroy altars? If not, is it possible that something else went on because of the unusual spawn instead? Techhead7890 (talk) 20:46, 7 April 2018 (UTC)

Altars should not be destroyable by Purification Powder. I wonder, did it register as you smashed them (i. e. spawning Hardmode ores), or did they simply disappear? Either way, it sounds like a bug and should be reported to the forums. The unusual spawning of the Altars is the bug and the Purification Powder destruction is related to that. – ReedemtheD3ad!

Corruption/ crimson spread

I'm trying to rid one of my crimson biomes and I was wondering if altars spread their respective biomes. Whenever I get rid of all the surface crimson using a clentaminator it keeps spreading back. TheTwilightlord (talk) 06:54, 13 March 2019 (UTC)

Is the world in Hardmode or pre-Hardmode? The Altars only spread (or rather, "seed") Crimson when they are smashed. The mechanics of Crimson spreading is determined firstly by the state of the world (Hardmode or pre-Hardmode). – Ferretwings (talk) 12:08, 13 March 2019 (UTC)
See Evil Biome#Spread for information on the spreading mechanics. – Ferretwings (talk) 14:06, 13 March 2019 (UTC)

Lacking information on where ore generates

This page, in its current state, is lacking a lot of information on HOW it generates. Like where it can generate and what blocks it can replace. For example, every tier of ore has a different minimum depth (and may have a maximum depth), and cannot generate within a certain distance (somewhere between 70-100 tiles) of the (true) world border. Also it can replace most naturally generating blocks, but not all naturally generating blocks, a list here would be helpful, instead of just "most blocks". A1 (talk) 01:14, 12 April 2023 (UTC)

Nevermind, I found a page with the information I was looking for. However, a link should be added, but idk where it could be added without feeling forced. this is the link btw. -A1 (talk) 22:25, 2 May 2023 (UTC)
Good point! I added the link. --Rye Greenwood (talk) 00:35, 20 May 2024 (UTC)
