About this Mod
🎲 Player-Level Randomizer

A chaotic survival mod for Minecraft where experience levels trigger random events, protect players from damage, and can be spent on permanent upgrades.
🛡️ The XP-Shield System
Your XP levels can protect you from incoming damage.
- Damage Absorption: If you have more XP levels than your protected bank level, one level is consumed to block one damage event.
- Level Bank: Bank upgrades protect a number of your levels from being spent by the XP shield.
- Exception: Damage that bypasses invulnerability, such as the void, is not blocked.
🎲 Level-Up Events
Leveling up triggers a random event. Event intensity usually scales with the reached level, but heavy events are capped to avoid runaway crashes from large XP gains.
| Event | Description |
|---|---|
| Structure Invasion | Random structures such as pyramids, outposts, villages, fortresses, bastions, shipwrecks, and end cities appear nearby. |
| Loot Rain | A small number of random loot items fall from the sky. Loot is selected from village, outpost, end city, ancient city, bastion, fortress, and stronghold chests. |
| Block Shift | Nearby terrain slowly transforms into a random solid block. The radius is capped so the event keeps working at higher levels. |
| Effect Roulette | The player receives a random set of status effects. |
| Animal Invasion | Random animals spawn around the player. |
| Trial Arena | A rare arena event traps the area with a world border, spawns monsters, and rewards the player after the fight. |
| EXP Trader | One of three traders appears and sells permanent upgrades for XP levels. |
❤️ EXP Traders
Three traders can appear:
- Graser: Strength upgrades and early Extra Hearts.
- Wisp: Haste and Feather Falling upgrades.
- Gustaf: high Extra Hearts upgrades and Level Bank upgrades.
Trader upgrades are saved with the world and remain after restarting the game or server.
