AmethystSMP-plugin

This plugin adds the Amethyst plugin to Minecraft, including armor, tools, a mace, and a staff. Each item has custom crafting recipes and unique abilities. Players can view items and their recipes through a custom GUI.

To use the amethyst staff and mace use right-click to use the ability

The Commands:
/ag gui -- opens gui

/ag spawn amethyst_boss -- spawn amethyst boss

/ag spawn arena -- with the double command, you can spawn an arena

/grace -- adds 1 hour of grace period

/trust and /untrust -- trusts and untrust player to be not attacked and to be able again to attack

/extract -- extracts Ender Dragon egg from the chestplate

/ameritehelmet - active's ability of amerite helmet 'lightning ability'

/ameritechestplate - active's ability of amerite chestplate 'range ability'

/ameriteboots - active's ability of amerite boots 'speed ability'

BTW, you can apply the Ender Dragon egg to your chestplate, but you just need to drop it, and it will reveal a new dragon egg, which you can apply to the chestplate as the trim.
