# Alex's Caves

Reference datapacks connecting NTM radiation, protection and processing to Alex's Caves.

**since NTM 1.0.1**

These packs require NTM and one of [Alex's Caves Updated](https://github.com/fmpapierz/Alexs-Caves-Updated) or [Alex's Caves Continued](https://github.com/Codx-org/AlexsCavesContinued). The same ZIPs work on Fabric and NeoForge.

## Downloads

| Pack | Adds |
| - | - |
| [Core](https://movblock.mov/ntm-next/wiki/assets/downloads/ntm-alex-caves-core.zip) | Hazmat protection, mask filters, mob immunity, uranium ore and raw neodymium processing |
| [Radiation](https://movblock.mov/ntm-next/wiki/assets/downloads/ntm-alex-caves-radiation.zip) | Toxic Caves dose and placed-block radiation; requires Core |
| [Treatments](https://movblock.mov/ntm-next/wiki/assets/downloads/ntm-alex-caves-treatments.zip) | Radiation removal from three foods |

Put the ZIPs in the world's `datapacks/` directory, enable Core before Radiation, then reopen the world: `/reload` does not apply NTM's registries.

## Core

| Change | Declaration |
| - | - |
| Hazmat Mask, Chestplate, Leggings and Boots resist 0.12, 0.24, 0.18 and 0.06, as NTM's basic hazmat suit; the full set admits $10^{-0.6} \approx 25.12\%$ of radiation. | [Armor radiation resistance](https://movblock.mov/ntm-next/wiki/hazards-and-radiation/hazmat-protection.md) |
| Hazmat Mask gives `sand` protection and accepts NTM filters; gas protection needs an installed filter. | [Equipment protection](https://movblock.mov/ntm-next/wiki/hazards-and-radiation/equipment-protection.md) |
| The four-piece hazmat set counts as an NTM `hazmat` suit. | [Suit protection](https://movblock.mov/ntm-next/wiki/hazards-and-radiation/suit-protection.md) |
| `#alexscaves:resists_radiation` (Nucleeper, Radgill, Brainiac, Gammaroach, Raycat, Tremorzilla) joins `hbm:radiation_immune`. | [Tags](https://movblock.mov/ntm-next/wiki/hazards-and-radiation.md#tags) |
| Radrock Uranium Ore joins `c:ores/uranium` and shreds like NTM uranium ore. It carries no NTM item hazard; Alex's item effect remains. | Item and block tags |
| Raw Scarlet and Raw Azure Neodymium join `c:raw_materials/neodymium`: the shredder gives two neodymium powders; each raw item is 72 neodymium material units, one ingot. | [Shredder](https://movblock.mov/ntm-next/wiki/recipe-types/shredder.md), [material distribution](https://movblock.mov/ntm-next/wiki/recipes/material-distribution.md) |

## Radiation

| Change | Declaration |
| - | - |
| Toxic Caves add 0.5 RAD/s of exposure, reduced by NTM protection and immunity. | [Biome radiation](https://movblock.mov/ntm-next/wiki/hazards-and-radiation/biome-radiation.md) |
| Uranium Rod joins `hbm:hazard/pile_rod_uranium`; Unrefined Waste joins `hbm:hazard/block_waste`. | [Item hazards](https://movblock.mov/ntm-next/wiki/hazards-and-radiation/item-hazards.md) |
| Placed Block of Uranium, Uranium Rod and Unrefined Waste use `item_hazard` rates. Placed Radrock Uranium Ore uses a fixed emission of 0.00175 and saturation 0.35. | [Continuous radiation sources](https://movblock.mov/ntm-next/wiki/hazards-and-radiation/continuous-sources.md) |

Alex's Caves effects still apply.

## Treatments

| Food | Removes |
| - | - |
| Spelunkie | 10 RAD |
| Slam | 20 RAD |
| Green Soylent | 15 RAD |

Each [counter action](https://movblock.mov/ntm-next/wiki/consumable-treatments/counter.md) runs on eating and stops at zero. The foods keep their effects.
