NO FIRE 2.0 only changes how fire *looks*. It hides the burning overlay on your screen and shrinks fire on blocks. You still catch fire and take damage exactly as in normal Minecraft. Because the usual warning flames are gone, you need other ways to tell you are on fire.
Signs you are burning
- Health bar: Watch your hearts. Steady damage ticks with no mob nearby usually mean you are on fire.
- Sound: Burning has its own sizzling damage sound. Keep game audio on, even if music is off.
- Low fire on the ground: With the pack, fire on blocks is short. Look down when you cross the Nether, such as a crimson forest, so you don't walk through patches without noticing.
Putting yourself out
These vanilla methods still work:
1. Jump into water, or place water at your feet with a water bucket.
2. Stand in rain or snow if the weather allows it.
3. Drink a Potion of Fire Resistance before Nether trips or fights near lava and fire.
The clear view makes it easy to forget you are burning. Treat any unexplained damage as fire until you know otherwise, especially while exploring the Nether.
