Farming gems—known as Diamonds—in 99 Nights in the Forest takes smart planning and knowing when and where to strike. Here's a breakdown of the most efficient strategies to stock up and unlock powerful classes or upgrades.

What it is: A challenging raid event where players face waves of cultists and gain access to a treasure room.
Rewards:
Key perk: The raid resets every 20 minutes (real time), allowing you to repeat it rapidly for continuous gains.
Why it's top tier: Although tough, the repeatable nature makes it the most dependable long-term method.
How it works:
Reward: Diamonds are awarded based on the badge's difficulty tier—tougher tasks yield more.
Pro tip: Aim for accomplishments like surviving 55 or 99 nights, which grant generous Diamond bonuses.
If you’re looking to maximize your badge rewards without the grind, the best alternative is checking out the 99 Nights in the Forest Diamonds shop, where you can quickly secure enough gems to unlock classes, upgrades, and cosmetics without waiting on long survival milestones.
Simply staying alive pays off—literally:
Combine survival with day multiplier maximization and quick rescues of missing children to get more value per run.
What to expect:
Note: These events are rare and time-limited, but can yield HUGE Diamond boosts when available.
Players share that Cultist gems (like necklace drops) are tied to the cultist raids:
“Those are cultist gems. You can raid the cultist stronghold to get 2, or kill all cultists when they come attack you to get 1.”
