Addon: OP Loot Kit
OP Loot Kit gives every player one powerful starter set when they first join the world.
Author: Sycuregaming-01
The kit contains Netherite armor and tools, sword, bow, trident, shield, cooked food, golden apples, a map, compass, buckets, building materials, torches, ender pearls, obsidian, Elytra and fireworks. Hold equipment once to apply all included enchantments.

Each player receives the kit only once, including in multiplayer, Realms and servers. It is not granted again after death or rejoining. No commands or cheats are required, so achievements remain available.
The one-time marker is stored separately for every player. This prevents duplication after respawn while still allowing a new participant to receive a personal kit.
The equipment covers immediate exploration, combat and Nether travel. Elytra and rockets provide mobility, while obsidian, buckets, food and building blocks support early survival. Enchantments are applied when each relevant item is first held.
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.
