How to Get the Assassin Class for FREE in 99 Nights in the Forest

If you’ve been grinding 99 Nights in the Forest, chances are you’ve looked at the Assassin class and wondered how to unlock it without spending Robux. It’s the most expensive and arguably the best class in the game, offering powerful combat bonuses that let you handle cultists, bosses, and survive 99 nights with ease. While unlocking it usually takes a long time, there are proven ways to get it for free — without shortcuts, pay-to-win, or game-breaking glitches. Here’s your complete step-by-step guide to unlocking the Assassin class without spending money.

What is the Assassin Class & Why is it Hard to Get?

The Assassin class sits at the top of the class list, costing 500 diamonds to unlock — the highest in the game so far. Compared to other classes, it brings strong combat perks, which makes it ideal for speedrunning strongholds or pushing past day 99.

However, diamonds are not easy to earn, especially after you’ve claimed all the one-time badge rewards. To get Assassin without paying, you’ll need to understand both the repeatable methods and one-time methods to earn diamonds efficiently.

Tips & Tricks to Unlock Assassin for Free

1. Play With a Full Party of 5

Having a full squad drastically boosts your progress. A full group lets you:

• Complete tasks like saving kids and crafting beds faster.
• Raid cultist strongholds efficiently.
• Survive longer, which means more diamonds per run.

Solo is possible, but slower. With a team, you can consistently earn 15–18 diamonds per session.

2. Complete the Cultist Stronghold

This is a repeatable activity that gives 5 diamonds upon a successful raid. It’s tough, so always bring a squad and be well-geared.

3. Reach 50 and 99 Days

• Day 50 = 2 diamonds
• Day 99 = 3 diamonds
  Completing both milestones in a single run gives you 5 diamonds, and if combined with stronghold runs and chest hunting, you can earn close to 18 per session.

4. Find the Diamond Chest

In the castle structure, there’s a Diamond Chest that drops diamonds and legendary loot. Use speed-boosting chili fruits and fight off waves of cultists to access it.

5. One-Time Badge Diamonds

These are your easiest early-game gains. Focus on:

• Surviving to Day 100
• Reviving teammates
• Defending the campfire
• Building oil drills
• Stepping on a bear trap and dying (yes, it’s a badge!)
  Many of these tasks give 1–5 diamonds and add up quickly on your first playthrough.

6. Choose the Right Starter Class

If you have a small stash of diamonds (around 30), buy Scavenger. It’s the best budget option with:

• +2 sack space
• Faster chest opening
• Scrap drops from chests

This class boosts your efficiency in every run, helping you earn more diamonds quicker.

Avoid classes like Camper (flashlight is useless early on) or Hunter (high cost, low impact). Focus on efficient classes, or just skip all until you hit 500 if you’re confident.

7. Diamond Farming Math

Here’s a possible breakdown per efficient run:

• Cultist Stronghold x2 = 10 diamonds
• 50 Days + 99 Days = 5 diamonds
• 3 Chest Diamonds = 3 diamonds
  That’s 18 diamonds per 60–70 minute run.

At that pace, you’d need around 28 runs to hit 500 diamonds — about 30–35 hours total, if consistent.

Unlocking the Assassin class in 99 Nights in the Forest without Robux is all about efficiency, teamwork, and planning. Focus on repeatable diamond sources like raids and milestones, take advantage of badges early on, and choose useful starter classes like Scavenger. Play in full squads when possible, farm smart, and keep pushing for those 99 nights. With time, you’ll not only unlock Assassin — you’ll dominate the game with it.
