🎁 Reward players with gems

Any plugin that can run a console command can give gems.

eg give <player> <gem> [level] [amount]
eg tool <player> <socket_drill|gem_extractor|gem_forge|rough_gem|gem_codex> [amount]

From a quest, a crate, a shop

Use the command with the player placeholder of that plugin, for instance:

eg give %player% vampire 3
eg tool %player% socket_drill 1

From an ExecutableItem

A scroll that gives a random stone when used:

activators:
  activator0:
    option: PLAYER_RIGHT_CLICK
    usageModification: -1
    commands:
      - eg tool %player% rough_gem 1

A gem for one item only

Make a gem that only fits one of your ExecutableItems items:

applicable-on: ['ei:Excalibur']

Sell a ready-made weapon

eg apply acts on the item in the player's main hand and can't fail, which suits a ceremony or an NPC:

eg apply %player% vampire 5
eg level %player% vampire +1

Check that the player holds the right item first.
