How to Beat the Cultist King in 99 Nights in the Forest
The Cultist King is the volcanic-biome boss. Community sources report that placing four Cultist Gems at the Cultist King Palace summons it, and that it is the gate to the Infernal equipment line. Treat the gem cost as the real difficulty — the fight is the last step, not the first.

- Farm four Cultist Gems first. Sources point to the Ice Temple, fishing, Cultist kills and the Cultist Stronghold as gem sources.
- Bring volcanic-biome survivability: heat route planning and a return path you have already cleared.
- Enter with full armour. The Infernal Helmet line needs Scorpion Shell plus Cultist King Antler, so this boss is part of an equipment chain, not a one-off.

What to expect
Fight notes
- The summon is a resource check: 4 Cultist Gems before the fight even starts.

General boss rules
Plan the retreat before the fight. In 99 Nights in the Forest the return trip is consistently more dangerous than the encounter, because you leave with less health and the night does not wait for you.

Pool, not guarantee
Treat these as a reward pool with limited source agreement, not as a guaranteed drop. We mark each row individually rather than averaging them into a single claim.What fails runs
Common mistakes
- Walking into the Volcanic Biome without four gems banked.
- Treating the reward list as guaranteed. It is a pool, and our sources disagree on parts of it.
- Attempting the run when the camp cannot hold without you.
What to do next
- Confirm you have the summon or trigger requirement before travelling.
- Recheck this page after our next in-game boss pass.
