Underworld Sands¶
Tensura · Minecraft 1.21.1 Biomes
Underworld field reference
Survey the sands. Watch for Megalodons.
An Underworld biome eligible for Ruins, with Megalodons, Daemons, and a configured 101,000-Magicule baseline.
Artifact and configuration checked · live world untested
This is a biome, not a collectible terrain block. The guide checks Tensura 2.0.1.2 resources and the tracked TSR configuration. Actual spawning, generated terrain, structure locations, and chunk Magicules have not been measured on the server.
Spawns¶
The base biome list and the tagged NeoForge additions are shown separately. Arch Daemon is added through a biome modifier, rather than appearing in the base biome JSON. Greater and Lesser Daemons also have Hell-tag additions; those entries are not collapsed into invented percentage chances.
| Mob | Weight | Group range | Resource route |
|---|---|---|---|
| Megalodon | 70 | 1–1 | Biome definition |
| Lesser Daemon | 40 | 1–1 | Biome definition |
| Greater Daemon | 5 | 1–1 | Biome definition |
| Arch Daemon | 1 | 1–1 | Hell-tag spawn addition |
| Greater Daemon | 30 | 1–1 | Hell-tag spawn addition |
| Lesser Daemon | 60 | 1–1 | Hell-tag spawn addition |
Weights are relative selection inputs, not spawn percentages or measured encounter rates. Group bounds, spawn costs, placement rules, area Magicules, other add-ons, and server data packs can affect the final result. The checked Hound Dog biome modifier targets Overworld tags; its presence in Barrens and Spikes instead comes from their own base biome lists.
Magicules¶
Tracked base
500¶
Base chunk Magicules in the tracked area configuration.
Hell level modifier
+100,000¶
Packaged ADD modifier for tensura:hell.
Biome modifier
+500¶
Packaged ADD modifier for this biome.
These three additive inputs give a 101,000 reference baseline before other modifiers. It is not a guaranteed current chunk reading or a personal MP grant. Generation, regeneration, magic engines, and server overrides can change the area value.
Regeneration inputs
The tracked base regeneration is 10; the Hell resource has a MULTIPLY 2 regeneration modifier, and this biome has an ADD 50 regeneration modifier. No final rate or modifier-order result is asserted without checking the applying implementation and live server.
Terrain and structures¶
The packaged biome feature list includes tensura:floating_debris. Precipitation is disabled in its definition. Landscape artwork is atmospheric illustration, not evidence of a particular castle, landmark, or terrain shape in game.
The packaged tensura:hell/sand_ruin structure targets a biome tag containing tensura:underworld_sands. Its placement set uses spacing 5 chunks and separation 4 chunks. Eligibility and placement parameters do not promise a ruin at a particular location or in already-generated chunks.
