The Demon Crystallizer is a device added by Blood Magic for Minecraft 1.8.9 and above. It is used for growing Will Crystals Clusters by draining the chunk's Aura, created in a Demon Crucible. Each Crystal Cluster can have 7 crystals maximum. A default Raw Will Aura has a 90% chance of Demon Will Crystal Cluster and 2.5% each for Corrosive Will Crystal Cluster, Destructive Will Crystal Cluster, Steadfast Will Crystal Cluster, or Vengeful Will Crystal Cluster. All other Aura types will only grow new Clusters of its own type. Once formed into a Crystal Cluster, only Raw Will or the Aura of its type can be used to grow additional crystals. Raw Aura is significantly slower at growing clusters of different types.
A Will Crystal Cluster can be broken with a pickaxe, yielding one Will Crystal per crystal. A single crystal can also be harvested by right clicking with an empty hand while holding a Tartaric Gem with over 1024 Raw Will total across gems. Right clicking will not remove the last crystal in the cluster.
Note: Requires the player to have at least 500 Will and will drain 100 Will on crafting.
