Content Table visuals

I just added biome variants of hardened sand and sandstone blocks to the "from terrain" section, but it throws the look of the table off. I wasn't sure how to make it so that the terrain section had two lists underneath it without going to the other side. If someone else could do that, the page would look better while showing all the info. Or the variants may not be needed because the pages are supposedly going to get merged at some point. Whatever the community thinks is better. Cainamar (talk) 22:51, 17 July 2015 (UTC)

Needed Information About Loot From Chests

There's no information about loot from the Golden Chests found in Underground Cabins. Anyone can add this information? I had no time to add this information... SteveisNoob (talk) 17:15, 31 January 2016 (UTC)

What amount of X block is taken to consider an underground desert.

We know that 1k sand blocks creates a desert biome, but what amount of walls or blocks create an Underground Desert? Frenchiveruti (talk) 19:57, 9 September 2016 (UTC)

Exact Rules For Underground Desert Mob Spawns and Biome

Underground Desert Mob Spawn Rules:

A generic spawnable block must have 49 tiles of natural hardened sand or sandstone wall directly above it AND 1 behind the block itself (for a line of 50). The player must be below the sky layer. That's it.

Requirements for the underground desert BIOME (max spawn rate and desert key drops, but not mobs):

The player must be in a desert biome (1,500 sand) while standing in front of natural hardened sand or sandstone wall. Music may not play in certain areas, but the biome still seems to work everywhere. I can't be 100% certain on that bit simply because I'm basing it on perceived spawn rates and I haven't tested that aspect as thoroughly in, for instance, space.

"Natural" hardened sand/sandstone walls can be made artificially by crafting the wall, placing it, then using the clentaminator on it. Corruption/hallowed makes no difference and doesn't count towards those specific biomes.

The underground desert biome theoretically reaches the game's "hard cap" for spawnrate even without a water candle or battle potion, but that may only apply when mobs are being killed the instant they spawn since living mobs slow the spawn rate. This makes it an appealing addition to an afk mob farm setup, especially a biome key farm since the tedious 1,500 sand is already a requirement. Simply place and clentaminate a couple pieces of wall behind your player's head in the afk spot. Many existing mob farm designs add an enclosed jungle biome to increase the spawn rate. Having both biomes at once will default to the underground desert's higher spawn rate.

Incorrect information about spawning mechanics

The Spawning mechanics section states that "The wall behind the spawn point and the 49 tiles above it must each be either Sandstone Wall (or its "tainted" variants) or Hardened Sand Wall (or its "tainted" variants)".
However as of 1.4.4.9 I can get unique monsters to spawn with only 6 tiles (and possibly less?) of valid background walls.

I haven't checked the code but my farm only has walls two tiles high and it still works (it may work with only one too, I haven't checked). I think this was done to accommodate the new treacherous sandstone/hardened sand walls. I think the spawning mechanics section should be updated to reflect this, and to make clear the difference between natural and artificial walls, to avoid confusion.

I'm the one who wrote the spawn condition talk above this one. I wasn't paying attention to how signatures worked at the time. 1.4.4 silently changed the spawn check from a column of 50, down to just the 1 wall behind the spawn block. I have edited the spawn mechanics and changes sections to reflect this. I confirmed this back when it happened, but was only just reminded of the relevance to the wiki just now. Sorry.
