As it stands Dark essence fragments are items created by using a chisel on dark essence blocks, providing 200 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 111 fragments at a time. The fragments cannot be stored in a bank. Dark essence fragments do vanish upon death.
My suggestion, Increase the 111 fragment limit, This will NOT increase the amount of blood runes the player crafts it will only increase how many essence the player can physically carry to the altar.
My suggestion is 444, (4x the limit meaning the player can mine 8 invents of essence blocks per run instead of 2)
