Modifier Flames in 99 Nights in the Forest change how a run plays out. Instead of activating modifiers from the lobby like before, players now apply them directly to the campfire during a match. This system adds more control, but it also comes with strict timing rules.
Here is everything players need to know about how Modifier Flames work, how to use them, and how to unlock them.
How Modifier Flames Work
Modifier Flames are special upgrades that affect the campfire and trigger specific events. Most flames guarantee certain Day 3 events, while others provide passive bonuses such as reduced campfire drain during weather.
The biggest change is that flames are now used in-game. Players must craft a Supply Crate and apply a flame before progressing past Day 1. If the campfire advances to Day 2 without applying a flame, that run cannot use one.
This makes early-game setup important. Rushing the campfire can lock players out of using their modifiers.
How to Use Modifier Flames
Using a Modifier Flame is simple once the process is understood.
After starting a run and reaching Day 1, gather wood and light the campfire. Do not fully fill the fire bar. Keep it partially lit.
Next, craft a Supply Crate from the Crafting Bench. The Supply Crate can only be crafted once per run. After placing it in camp, select one of the unlocked Modifier Flames.
Once the flame is applied, finish lighting the campfire. The chosen effect will now carry into the run, usually impacting Day 3 events.

How to Get Modifier Flames
Modifier Flames are unlocked through gameplay progression and limited-time content. Most are tied to events, seasonal shops, badges, or special challenges.
Common ways to unlock flames include:
Completing badges
Participating in seasonal events
Buying from event shops
Finishing daily or event quests
Event-based flames are usually limited-time, meaning players must participate during active events like Halloween, Valentine’s, or other seasonal updates to unlock them.

Modifier Flames are best used when planning a specific strategy. If the goal is to farm certain event rewards, guarantee a specific Day 3 event. If survival is the focus, utility flames like Blue Flame can make weather-heavy runs more manageable.
The most common mistake is fully upgrading the campfire too early. Always apply the flame before progressing past Day 1.
As 99 Nights in the Forest continues to add seasonal content and new events, Modifier Flames will likely remain a key part of planning efficient and rewarding runs.
