crater_biomes | Fallout rain converts affected chunks to crater biomes; default true. | |
disable_nuclear | Removes the initial radiation pulse and the fallout rain of nuclear blasts; default false. | |
fallout_range | Fallout-rain radius as a percentage of 2.5r + a, where r is the blast radius and a the blast's extra fallout; minimum 1; default 100. | [0, \texttt{i32::MAX}] |
fatman_radius | Base radius of atomic-bomb airstrike bomblets (× 1.5), the Crashed Balefire Bomb (× 1.25) and the Micro-Nuclear Missile; default 35. | [1, \texttt{i32::MAX}] |
fleija_radius | F.L.E.I.J.A. blast radius; default 50. | [1, \texttt{i32::MAX}] |

schrab_ore_rate | Uranium ore hit by nuclear waste spread (ZIRNOX meltdown, Radioactive Barrel, Vitrified Nuclear Waste Drum) becomes schrabidium ore with chance 1 in this value; 1 never converts. Applies with Less Bullshit Mode on (lbsm.enabled in hbm-content.toml, 528 mode off); otherwise the chance is 1 in 250. Default 20. | [1, \texttt{i32::MAX}] |
solinium_radius | The Blue Rinse blast radius; default 150. | [1, \texttt{i32::MAX}] |
tsar_radius | Tsar Bomba blast radius with its full payload; default 500. | [1, \texttt{i32::MAX}] |
