999 Nights Guide
Quick answer: 999 Nights is a permanent single-player mode on the Warren Continent, played with four fixed characters: Esper Zero, Mint, Iroi, and Shinku. Clear four dungeons in order, starting with Chocolate Volcano, then beat the Crimson Dragon to finish your first run. You can replay it for a 2nd and 3rd playthrough with tougher enemies and more side quests. Reach Level 40 before your 2nd run, and collect Mystery Buttons for outfits and other rewards.
999 Nights is a fantasy adventure that plays very differently from the main game. It starts from scratch, so anyone can jump in, and it rewards you for coming back.
What Is 999 Nights?
999 Nights is a permanent single-player mode in Neverness to Everness (NTE). It takes place on the Warren Continent, a fantasy world that is separate from Hethereau. It was added in Version 1.2 on July 8, 2026.
The idea is simple. 999 Nights is an Anomaly that works like a tabletop game, and the players are sent into the board to live out the adventure.
- It is single-player and permanent, so you can play it any time once it's unlocked.
- It uses a class system, and each class has its own gear.
- You level up by defeating enemies, not by using your main-game upgrades.
- Your main-game character levels and gear don't carry over. Awakening and Resonance effects do, according to one guide.
How to Unlock and Enter 999 Nights
The mode unlocks during the Version 1.2 main story quest "Fighting with a Dragon". One guide places this early in Main Story Chapter 7.
Once it's unlocked, you can go back in whenever you like:
- Warp to Mint's house in New Herland District.
- Interact with the board on the desk.
You can also warp straight to Mint's house from the 999 Nights section of the Event screen.
The Four Classes
Only the four characters introduced with the mode can play it. Each one has a fixed class.
| Character | Class |
|---|---|
| Esper Zero | Swordsman |
| Mint | Barbarian |
| Iroi | Mage |
| Shinku | Dragon Knight |
Each class has its own gear and feel, so you can't swap in your favorite main-game team. Shinku becomes a Dragon Knight late in Chapter 7, which lets her equip powerful gear and unlock her Ultimate.
How the Three Playthroughs Work
Your first clear isn't the end. After you beat the Crimson Dragon, your next run starts automatically as a harder replay.
| Run | What changes |
|---|---|
| 1st playthrough | Learn the systems. Clear the four dungeons and beat the Crimson Dragon. |
| 2nd playthrough | New side quests unlock, and some enemies appear at higher levels. |
| 3rd playthrough | Defeat the Crimson Dragon again to unlock it. Enemies are tougher, and better gear is available. |
The mode has three difficulties: Story, Challenge, and Nightmare. One guide ties Challenge to the 2nd run and Nightmare to the 3rd.
The Four Dungeons
In every run, you clear four dungeons, starting with Chocolate Volcano.
- Chocolate Volcano
- Milk Ice Mountain
- Amber Syrup Lake
- Crimson Castle
Your main goal in the first run is to defeat the Crimson Dragon. Strengthen your characters along the way before you take it on.
Leveling and Gear
You level up by defeating enemies in the field and in dungeons. From the 2nd dungeon onward, there are minimum level requirements, so keep fighting on the way. The level cap is 100.
You get gear from enemy drops and from the Mysterious Fuzzy Merchant, who appears at camps and inside dungeons.
- Gear has level requirements. A character can only equip gear at or below their current level.
- Set effects make even low-rarity gear much stronger. Early on, it helps to keep Epic (purple) gear or better so sets are easier to finish.
- Gear comes in Common, Rare, Epic, Legendary, and Mythic rarities.
- Buffs with different effects can be active at the same time. If you use two buffs with the same effect, only the most recent one applies.
- Bonfires let you rest and restore resources. They also work as waypoints.
Tips for Each Playthrough
First Playthrough
- Follow the story first. The Chapter 7 quests teach the basic flow of a full run.
- Collect Mystery Buttons from side quests and treasure chests as you go.
- Aim for the "Appraise it!" Achievement. Less gear is available to appraise from the 2nd playthrough onward.
- Reach Level 40 before the 2nd run. Enemies get much stronger, and that level lets you equip the gear that drops on Challenge difficulty.
- Explore the whole map first. Right after the 2nd run starts, only Chocolate Volcano is open.
Second Playthrough
- Clear side quests. More of them unlock now, and they pay valuable rewards such as Mystery Buttons.
- Keep leveling toward 100. Enemy levels rise sharply.
- Defeat the Crimson Dragon again. Then exit the Warren Continent and start the 3rd run from the 999 Nights start screen.
Third Playthrough
- Save your Warren Gold Coins. Reaching Level 100 with about 4,000,000 gold lets you buy the "Ultra Sparkle Jar - Nightmare" from the Mysterious Fuzzy Merchant at the start of this run.
- Upgrade your gear. Gold (Legendary) gear and Mythic weapons are easier to find now, so pick pieces carefully.
- Try the hidden boss. At Level 100, a portal near Amber Syrup Lake leads to the "???" boss. It's the toughest enemy in the mode, and it drops a special weapon.
Dragon Keep Challenge
Version 1.3 added a floor-based challenge to Dragon Keep, with two modes:
| Mode | How it works |
|---|---|
| Standard Mode | 99 floors. Defeat every enemy on a floor to move up. |
| Infinite Mode | No floor limit. Keep climbing as long as you can. |
Mystery Buttons and Rewards
Mystery Buttons are the main currency of 999 Nights. You earn them from side quest rewards and treasure chests around the world.
- Spend them in the Button Shop on the Event screen.
- The shop offers exclusive outfits, and you can also exchange Buttons for Annulith, frames, and training materials.
- 999 Nights also has its own Achievements that reward Annulith.
Common Mistakes
- Skipping the map in the first run. Your next run starts with only Chocolate Volcano open, so explore before you finish.
- Ignoring side quests. They're a steady source of Mystery Buttons.
- Entering the 2nd run under-leveled. Enemies hit much harder, so aim for Level 40 first.
- Spending all your gold. Saving gold gives you a better start in the 3rd run.
- Forgetting the Achievements. "Appraise it!" is easiest to get in your first playthrough.
