The basalt deltas are a volcanic biome found in the Nether.

Description

[edit | edit source]

The basalt deltas is the second rarest Nether biome, making up around 16% of the Nether by volume, and can generate next to any other Nether biome except for the crimson forest.

The rough and jagged terrain of basalt deltas is composed largely of basalt and blackstone and features numerous deltas, shallow pools of lava, and magma blocks, typically reaching depths of 1 to 3 blocks. The biome's fog is a dull lilac color, and ambient ash particles float through the air. Archipelagos with islands of different sizes can be found around the lava seas nearby. On the ceiling, glowstone blobs generate as usual. Both brown and red mushrooms still grow in this biome on top of the basalt blocks.

Nether fortresses and ruined portals can be found here. Nether quartz ore, Nether gold ore, and the rare ancient debris generate underground, but are more difficult to obtain due to the abundance of deltas and lava seas. Ore also spawns more frequently to compensate for the significantly reduced amount of netherrack in the biome. Bastion remnants are not present, making basalt deltas the only Nether biome to not feature them.

Magma cubes have a higher spawn rate in this biome than in any other biome. Occasionally, a ghast can be spotted. Like in all Nether biomes, striders wander the lava lakes, and sometimes spawn trapped in the countless deltas.

Mobs

Trivia

[edit | edit source]

Basalt deltas have no unique mood-based ambient sounds in dark areas and instead borrow those of the Nether wastes.
According to Felix Jones, the basalt deltas biome has a subtle Easter egg that has not yet been found by anyone.^[1]
Much of the ambience in the basalt deltas resembles the clicking of a Geiger counter, used to measure radioactivity.
- During the ambience creation process, Brandon Pearce provided the keyword "radiation" to audio director Samuel Åberg,^[2] which may explain its purpose.
