The rare components that used them in crafting, like Oleron’s Blood or Arcane Spark, used to require 12 (12!!!) Chthonic Seals of Binding [0]. For a crafting material that mostly dropped from only some human Bloodsworn / Cult of Chthon members, that couldn’t be built or bought, couldn’t be obtained through dynamiting items (I think?), couldn’t be gambled or exchanged at Participating Blacksmiths Near You [1] (cmon Egellon), and wasn’t in Treasure Troves (I think?), they were pretty expensive.
