The Floo
Java mod listed for Minecraft 1.16–1.20. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Careful of the Floo!
- This is a new effect that slightly decreases your maximum health
- The incubation period is looong!
- It is highly infectious to all living beings within a small radius
- Scientists believe that it orgininated from witches brewing with dead things!
- It is said that roughly every 20th witch is carrying this potion effect herself
- Players who waited out the effect have built up an immunity against it
Features
I already explained them :P
- Decreases maximum health by -10% (used to be -8%)
- Stays for up to 4.6 hours (276 minutes)
- Spreads to all living entities within 1.5 Blocks from any affected entity
- Bats have drops now which you can use to brew the Floo potion (with Nether Warts); Combine with Redstone or Glowstone
- Every 20th witch might have the effect on her; Get too close to her and you will be infected
- After it runs out you will be immune to The Floo for quite a long time
- Buy a very short (but strong) version from a Journeyman Cleric villager to build up immunity quickly
Seriously Infectious!
It really turned out highly infectious! In the testing world I accidentally infected an actual bat with it which just flew around in the spawn area, infecting many more animals, which also infected many more etc..
