Overview[1]
The Volcanic Biome is a lava-filled region with cultist-guarded landmarks, scorpion pits, a sacrifice altar and the Cultist King Palace. It becomes available after the campfire reaches level 2; several of its rewards require exploring deeper landmarks.

First route
Expect dark stone, scattered lava pools and little vegetation. The biome contains a cultist palace, an ammo furnace, a church, watchtowers, scorpion pits and blue- or red-spiked chests. Bring ranged damage and healing before pushing into guarded landmarks.
Volcano altar
At the volcano, offerings dropped into the lava charge an altar. The source wiki describes a reward every eight charges: a Gem of the Forest fragment, then Cultist Gems, then an Infernal Sword or Crossbow. Sacrifice Totems count for two charges. The volcano itself is usable after the campfire reaches level 4.
Cultist King Palace
Four Cultist Gems placed on the throne-room pedestals summon the Cultist King. The palace is defended by cultists before the boss arrives. Defeating him can provide a Cultist King Antler, Mossy Coins and infernal equipment; his mace is not a normal drop.
Equipment to look for
Red-spiked chests can hold the Infernal Sword or Crossbow. Blue-spiked chests can provide Sacrifice Totems and a Lava Mine Blueprint. Six Scorpion Shells plus a Cultist King Antler can be crafted into an Infernal Helmet at the Tool Workshop.
Hazards
Lava pools cause burning, and scorpions or cultist groups can overwhelm players who enter a pit or tower without clearing guards first. The Infernal Helmet blocks ordinary lava damage, but it does not protect against the lava inside the volcano.
