💰 Control loot and prices

Everything about how players get gems is in config.yml and in the obtain section of each gem.

A monster dies or a chest is opened, the loot chance is rolled, then a tier with tier-weights, then a gem with obtain.weight. The gem drops at the first level of its tier.

Make gems rarer or more common

loot:
  mobs:
    chance: 0.002        # 0.2% instead of 1%
    looting-bonus: 0
appraisal:
  drop-chance: 0.01      # Unidentified Gems: 1% instead of 3%

Change a tier's odds

loot:
  mobs:
    tier-weights: {1: 90, 2: 9, 3: 1, 4: 0}   # Radiant gems never drop

Make one gem rarer

In the gem's file:

obtain:
  weight: 2        # against 10 for a normal gem
  min-tier: 2      # never found Chipped

The chance of a gem is its weight divided by the sum of the weights of the gems available at that tier.

A gem nobody can find

Perfect for a quest reward or a shop:

obtain:
  weight: 0

Then give it by command. See Reward players with gems.

Only some gems in the loot

loot:
  gems: [vampire, frost, ember]
appraisal:
  gems: [vampire, frost, ember]

No random gems at all

loot:
  mobs: {enabled: false}
  chests: {enabled: false}
appraisal:
  drop-chance: 0

Change the jeweller's wares

Up to 4 wares. item is a tool id or gem:<id>:<level>.

jeweller-shop:
  wares:
    stone: {item: rough_gem, price: 'EMERALD:4', xp-levels: 0}
    opal: {item: 'gem:blood_opal:1', price: 'DIAMOND:3', xp-levels: 5}
    drill: {item: socket_drill, price: 'EMERALD:32', xp-levels: 10}

Keep forges for admins

Remove the forge line from jeweller-shop.wares, so players can't buy one, and place the forges yourself with /eg forge.

Fewer or more sockets

sockets:
  default-weapons: 0
  max: 2
  default-per-material:
    NETHERITE_SWORD: 2
