Caustic Slopes

Toxic terraced slopes of rust-coloured rock, with caustic water, gas fields and geysers.

Version: 0.1.0-pre-alpha

Rust-red rock climbs in countless offset steps, cut by ravines and pools of green, caustic water. The whole land seems to breathe: gas fields hiss, the ground seeps and geysers rumble. Every hazard warns you before it strikes, and standing in the water or the gas leaves you Caustic. Only the creatures born here are immune. A Caustic Filter is the best thing you can bring.

Spiteful Larvae slowly gnaw the caustic stone into porous rock, Sulgills guard their nests and Veilwings circle on the warm air above the geysers, looking for carrion. The dangerous ones come in packs or from above: Plague Rats in groups, the Pesta that calls them, Caustic Scorpions, Siphonflies that latch on to drink, and the Rotburster, which swells before it bursts.
