99 Nights in the Forest: Fastest Diamond Farming Methods

What Diamonds Are Used For

Diamonds are the premium currency in 99 Nights in the Forest.
You'll need them for:

Unlocking premium classes (Cyborg, Assassin, etc.)
Buying rare upgrades
Skipping certain grindy requirements

Key Fact:
The fastest way to farm them is Cultist Stronghold speed runs, but there are also passive ways to stack them over time.

Main Farming Method – Cultist Stronghold Speed Runs

This is hands-down the best diamond per hour ratio in the game.

Why This Works

Each Cultist Stronghold run gives a Diamond Chest → 5 Diamonds.
A well-coordinated team can clear it in 20–25 minutes.
That's 12–15 Diamonds/hour if you keep momentum.

Step-by-Step Run Plan

Step 1 – Get Your Team Ready

Ideal team: 3–4 players.
Include at least one Alien class → infinite ammo saves huge time.
Voice comms help—call out enemy positions and skips.

Step 2 – Stock Up Before Entering

Food: Cooked meat/mushrooms for quick healing.
Healing items: Bandages or medkits—don't rely only on food regen.
Ammo: Everyone except Alien needs full stacks.

Step 3 – Execute the Speed Run

Sprint past trash mobs—kill only what's blocking the path.
Take shortcut routes where possible.
Save ultimates for the Cultist High Priest boss.
Avoid his AoE—bait attacks, then punish.

Step 4 – Cash Out and Repeat

After looting the Diamond Chest, immediately restart the mission.
With no breaks, you can fit 3 runs/hour.

If you want to skip the grind and get your upgrades faster, you can always buy 99 Nights in the Forest Diamonds from a trusted marketplace for instant progress.

Location	Forest Zone – Mission Terminal
Reward	5 Diamonds per run
Run Time	~20–25 mins (fast team)
Difficulty	Medium (easy with Alien + healer)
Best Tip	Skip unnecessary fights to save minutes

Secondary Diamond Sources (Passive Gains)

These won't match Stronghold runs but are good side grinds.

Method	Diamonds	Notes

Legendary / Gold Chests	Random	Rare drop—good if you're already exploring
Cultist Attacks	1–2 each	Kill all cultists during raids for bonus loot

My Recommended Daily Diamond Loop

Run Cultist Stronghold 2–3 times with a fast team (main income).
During downtime, finish quick achievements or hunt badges.
Kill cultists during raids if they show up while you're prepping.
Loot every Gold/Legendary Chest you pass in free roam.

Extra Player Tips

Alien class = MVP for ammo efficiency and speed.
Don't over-prepare—every minute spent in the lobby is lost farming time.
Shortcut knowledge saves runs—learn every path inside Stronghold.
Balance grind with fun—swap to passive farming if you're burning out.
