In structure you can find different rooms with challenges in them. In this structure you can find chests and vaults with loot like starting gear and food and also new enchantments.
This structure is underground tunnel system with different challanges inside. Also you can find entrance to this structure on the surface so it's easier to find. In comparison with deepslate dungeon it has worse loot.
Cherry temple is insanely rare structure with really good loot in it. You can open vaults with totems of undying. And you can find something interesting under it.
This enchant is exclusive for bow. Allows you to shot 3 arrows at once.
Can be applied to bow and crossbow. Allows you to shot arrow which on hit summons lightning.

My first datapack adding a new underground structure and some other things to the game to the game.
