A client-side Fabric mod that scrambles every inventory/container screen's layout the moment it opens - slots, panel, and buttons jump to random spots, but your clicks still land. Cosmetic and client-only. Configurable. Minecraft 1.21.x (Fabric).
A deterministic enchanting-table GUI replacing vanilla's random gamble. Forge enchanted books from ingredient blueprints (not consumed), then apply them to gear for a flat level cost. Reusable books. Paper/Spigot/Bukkit/Purpur 1.21.1-1.21.11.
Skyblock-style placeable minions that auto-gather a resource into their own storage on an upgradeable timer. Place by right-clicking a block; manage via the minion's GUI. Fuel, tiers, modules, offline catch-up. Paper/Spigot/Bukkit/Purpur.
A lightweight RPG skill tree. Spend XP levels and resource items in a chest-GUI to permanently unlock and level up passive skills: speed, mining, ore/crop bonuses, health, fishing. Persists per-player. Server-side; Paper/Spigot/Bukkit/Purpur.
Quantum blocks flicker between the real block and a random "anything" block until a player sees them, then collapse to one (coordinate-seeded). They spawn naturally underground and only shimmer near players. Server-side, Paper/Spigot/Bukkit/Purpur 1.21+.
Mobs gain a hidden emotional state (calm, panic, or rage) that spreads through same-type herds and decays. Hit one sheep and the flock stampedes; enrage a wolf and its pack turns. Server-side, Paper/Spigot/Bukkit/Purpur 1.21+.
The world ages as you use it. Walked routes wear grass into dirt paths, stone beside lava chars to blackstone, logs by water grow moss. A TPS-friendly aging system for Paper, Spigot, Bukkit, and Purpur 1.21+.
Placeable anchors that warp local gravity: attract, repel, or launch nearby entities. Right-click to cycle modes. Velocities are clamped and TPS-budgeted. Server-side, works on Paper/Spigot/Bukkit/Purpur 1.21+.
Animals gain a hidden weight from good husbandry - light, water, grazing, and space. Weight scales their drops and XP, so spacious farms out-produce cram boxes. Neglected animals get sick. Concept by u/Axoladdy.
