GemPlugin - Minecraft SMP Gem Abilities Plugin

GemPlugin is a Minecraft 1.21.x plugin centered around collectible gems, per-gem gadgets, custom crafting recipes, and combat-oriented abilities for SMP servers.

The plugin now targets the broader Bukkit-family API surface through spigot-api, so the same jar can be used on Paper, Purpur, and Spigot.

Features

16 Unique Gems

Each gem has three core abilities activated by click combinations, with cooldown scaling based on gem level.

Available gem types:

• Fire
• Ice
• Lava
• Sand
• Iron
• Lightning
• Strength
• Healing
• Air
• Water
• Shadow
• Speed
• Pain
• Mining
• Ender
• Gluttony

Per-Gem Gadgets

Every gem type has a matching gadget with its own 4th ability.

Gadget system highlights:

• One gadget per gem type
• Crafted from the matching gadget recipe layout with a Gadget Core in the center
• Normal right-click opens the gadget binding menu
• Shift + right-click activates the gadget ability
• Gadgets can bind to any gem using persistent item metadata
• Bindings can be removed and reassigned with /gem unbind

Gem Upgrading

Gems support level progression from 1 to 5.

Each higher level reduces ability cooldowns using the configured gem.gemlevelsteppercent value.
