Diamonds — In-Depth Analysis
Diamonds are the premium currency of 99 Nights in the Forest, and unlike wood or food they have nothing to do with hunger or combat. They exist purely to unlock classes, permanent perks, and cosmetic upgrades, so every one you bank is progression you keep across runs rather than survival fuel for the current night.
The grind is slow and deliberate. The most reliable steady income is passing day milestones: you earn 2 Diamonds for surviving past Day 50 and 3 for reaching Day 99, with both totals roughly doubling in Hard Mode (4 and 8 respectively). On top of that, clearing a Cultist Stronghold rewards a Diamond Chest worth 5, daily quests roll easy/moderate/hard objectives each in-game day, and the rare Chests occasionally cough up a single one.
Because they never decay and have no in-match use, the verdict is simple: grab every Diamond you see, prioritize the Day 50 and Day 99 thresholds on full runs, and tackle Cultist Strongholds whenever a squad can handle them. Diamonds are the long-term backbone of account power, so treat them as the reward for surviving, not as a tool that helps you survive.
