What’s new in Rainbow Lava Mod? 🌈🔥
Rainbow Lava turns your builds into high‑risk, high‑reward zones: it looks stunning in glass mazes and corridors, but it’s far deadlier than regular lava.
✅ Core features
- Vibrant rainbow effect — the lava flows with shifting rainbow colors, perfect for colorful mazes and glass‑walled corridors.
- Increased danger — deals significantly more damage than normal lava: even brief contact is a serious threat.
⏱️ Performance
- Color cycle updates every 20 ticks (1 second) for smooth flow without heavy load.
⚠️ Important note
Treat Rainbow Lava as a high‑danger element: its beauty hides a much stronger threat. Always test builds in a separate world first.
💡 Design tip
Frame the lava with glass to highlight the rainbow effect while keeping players at a safe distance — ideal for dramatic mazes.
