Including:
Mods to add new structures and revisit vanilla ones
Mods to increase the difficulty
Mods with new dimensions and new bosses
Mods aiming for a RPG progression, make the ultimate equipment
Mods that changes vanilla mechanics
Mods with automation and tech
Mods with magic
Mods for QoL
All of them tweaked with configs in an attempt to balance the modpack (except wanderer trades that I didn't manage to nerf with datapacks)
