Addon: Lucky Blocks (fs)
Author: FleetMCStudio
Lucky Blocks turns resource hunting into a risk-and-reward event. Breaking one of the two special blocks triggers a random result: useful supplies, highly enchanted equipment, hostile mobs or a dangerous situation that must be handled immediately.

Two block types

- Yellow Lucky Block favors rewards and has a lower chance of harmful events. It is crafted from eight gold ingots and a chest.
- Red Lucky Block offers more powerful loot but carries roughly a 45% chance of an unlucky outcome. Its recipe uses eight gold blocks and a chest.
The pool contains more than 40 lucky and unlucky events. Rewards range from ordinary survival materials to equipment capable of accelerating late-game progress. Negative outcomes can summon zombies and other enemies, surround the player with hazards or start an unexpected combat encounter.

Both blocks are available through normal survival crafting, making them suitable for a dedicated challenge map or as an optional gamble in a longer world. The different costs keep the yellow version accessible while reserving the red version for players willing to risk a larger investment.

The add-on supports multiplayer and achievements and does not require experimental features.
How to install the add-on
Download the .mcaddon or .mcpack file, open it with Minecraft and wait for the import to finish. Then enable the resource and behavior packs in the world settings. If the add-on requires experiments, turn them on before launching the world.
