Some Familiars require the help of Skillstones to activate their skills. Skillstones are unique to each familiar and can only be made when they reach the Elder Stage.
Most Skillstones can be made in the Mystic Spire by merging Anima and either Ancient Cores or Chaos Cores, depending on the strength of the skill. Only the Gryphon's skill does not require cores.
The cost for 1 Ancient Core is 1000 Gems, and 1 Chaos Core is 7500 Gems. To buy them in bundles of 10 are 9500 and 71250 Gems, respectively.
