Dark essence fragments are items created by using a chisel on dark essence blocks, providing 8 Crafting experience per block. Each block will create 4 pieces of essence, which are used to runecraft blood and soul runes. Players cannot hold more than 108 fragments at a time. The fragments cannot be stored in a bank. Dark essence fragments vanish upon death.
- Blood runes can be made at 77 Runecraft (can be boosted) and will provide 23.8 experience per dark essence fragment.
