Volcanic Crater and Peaks

Volcanic Crater and Peaks is the name for four overworld biomes built around volcanic terrain. Two come from Terralith: the Volcanic Crater and the Volcanic Peaks. The other two come from Biomes O' Plenty: the Volcano and the Volcanic Plains. All four are hot biomes with a mostly vanilla ore set, but each has its own lava features, ground blocks and rarity.

The Terralith pair receive rain. The Biomes O' Plenty pair have no precipitation. Within the pack, the Volcanic Plains are the most common of the four, while the Volcanic Crater is almost absent from the land. All four spawn a long list of horror mobs from the pack's mod roster, including the Dread Hound, so the biomes are dangerous at night.

Description

Volcanic Crater

The Volcanic Crater is a Terralith biome built as a volcano with a basin in its centre. The basin floor is made of basalt and smooth basalt, mixed by a noise pattern, and Terralith lays a blackstone layer 7 to 8 blocks deep into the volcano's stone. Lava lakes and lava flows are placed across the crater. The biome has ambient white ash particles drifting in the air at a probability of 0.0075, and its background music is the vanilla Stony Peaks track. The fog is grey-blue and the sky is a dark slate.

Volcanic Peaks

The Volcanic Peaks is the Terralith companion to the crater. It is tagged as a mountain peak, so it sits on high, rugged ground rather than in a basin. It has none of the crater's basin, lava-flow or magma-barrier features. Its placed features are the vanilla lava lakes, Terralith's spring lava, the same stone and ore set as the crater, and the usual cave urns and wild flax plants. Its fog is pale grey and its sky is hazy blue-grey, so the peaks look more washed out than the crater. It has no ash particles.

Volcano

The Volcano is a Biomes O' Plenty biome. It is rare in the pack, covering 0.05% of the land surface and 0.01% of the cave layer. Its lake floors contain magma disks and smooth basalt disks, which are placed in lava, and black sandstone disks are placed alongside them. It has surface lava lakes and a lava spring feature that places lava between Y 96 and Y 192. Its ambient white ash particles are denser than the crater's, at a probability of 0.059. Its background music is the vanilla Jagged Peaks track, and its fog is a dark grey.

Volcanic Plains

The Volcanic Plains is the most common of the four biomes, covering 0.37% of the land surface. Its grass and foliage are tinted dark green and its sky is a bright blue. Its surface features include mossy black sand splatters, grass and sprout patches, and a volcanic variant of Biomes O' Plenty's twiglet tree. The trees are placed one per chunk in most cases and two in about one chunk in ten. Unlike the Volcano, the Volcanic Plains has no ash particles and no magma or basalt disks. It does share the Volcano's lava spring feature, which places lava between Y 96 and Y 192.

Generation

The four biomes take their share of land from the pack's biome table, in which every biome allowed in a climate cell is eligible and the cell is split by weight. Terralith's biomes together cover about 31% of land in the pack and Biomes O' Plenty's about 25%, so the volcanic biomes sit among a large set of mountain and hot biomes rather than standing out as a special region.

Shares of the land surface in the pack are:

• Volcanic Plains: 0.37%
• Volcano: 0.05%
• Volcanic Peaks: 0.05%
• Volcanic Crater: 0.00%, which rounds down to nothing

The Volcanic Crater is therefore the rarest biome on this page. Players should expect to find it only with deliberate searching.

The four biomes are not horror-weighted. The pack's horror weighting raises the weight of dark forests, swamps, taigas and some caves, but it leaves deserts, jungles and peaks mostly normal, and these volcanic biomes fall into the normal group.

Features

All four biomes place the standard overworld ore set: coal, copper, iron, gold, redstone, lapis, and the vanilla andesite, diorite, granite and tuff stone variants. The Terralith pair and the Volcano also place emerald ore. The biomes also place several pack-added ores. Iron's Spells 'n Spellbooks places Mithril ore. Born in Chaos places Black Argillite and infected deepslate diamond ore. Butchery places Sulfur ore in deepslate. See Ores and Mining for how each ore is used.

The lava features differ by biome:

• Volcanic Crater: lava lakes, lava flows, a magma barrier, and a crater fixer that shapes the basin floor. Its lava springs come from the vanilla spring lava feature.
• Volcanic Peaks: vanilla lava lakes and Terralith's spring lava, which is placed between Y 110 and Y 290.
• Volcano: surface lava lakes, magma and smooth basalt disks in lava, and the Biomes O' Plenty lava spring feature, which is placed between Y 96 and Y 192.
• Volcanic Plains: vanilla lava lakes and the same lava spring feature as the Volcano.

All four biomes place vanilla amethyst geodes and monster rooms (dungeons). They also place cave urns from the Supplementaries mod, wild flax, and wild tomatoes from Farmer's Delight.

Mobs and structures

The four biomes share nearly one monster list. The only difference is the Nightmare (weight 7), which spawns in the Volcano and the Volcanic Plains but not in the Terralith pair. The most common hostiles are the vanilla Spider, Skeleton, Creeper, Slime and Zombie. Pack mobs follow, including the Slime Golem (weight 25), the Necromancer (weight 18), and many Born in Chaos mobs. The Dread Hound has weight 7, the Nightmare Stalker has weight 2, and the Krampus and Lifestealer have weight 1 each. Bats and Glow Squid appear in all four with the same weights.

The structure table on each biome is long, with more than 120 entries per biome. The highlights are:

• Luki's Grand Capitals pillager outposts, alongside the vanilla and CTOV pillager outposts. See Pillager Outposts.
• Firewell from Born in Chaos, which appears in all four biomes.
• Mountain Tower from Iron's Spells 'n Spellbooks, which appears in the Terralith pair and the Volcano.
• The vanilla mineshaft, which appears in the Terralith pair and the Volcano.

Tips

• Bring water and fire protection before you explore the crater basin, where lava lakes and lava flows are placed.
• Check the mob list before you travel through the Volcanic Plains or the Volcano at night. The Nightmare and the Dread Hound are both in the list, and the Nightmare Stalker can appear in the Terralith pair.
• The Volcanic Crater is rare enough that you should plan a trip to find it rather than walking into it by chance.
• Mithril and Born in Chaos ores are placed in all four biomes. They are the most useful reason to dig into the volcanic stone.
