FireHole Location ID

The location ID and world-generation details for FireHole in Valheim — the biome it spawns in and how many appear per world.

About

FireHole is a fire geyser found in the Swamp. It continuously spawns Surtlings and yields Coal and Surtling cores when the Surtlings die over water.

Overview

FireHole is a Valheim world location that spawns in the swamp biome, identified internally as FireHole.

World generation places up to 75 per world, with terrain constraints (altitude -1–1000 m; terrain delta 0–5 m), and an exclusion radius of 5m, which is why some seeds have far more of them than others.
