After the Mircona rocks, it was a cluster of Blood Sun gemstones, followed by non-descript herbs.
Liam assumed that the elf did not really care much about the herbs perhaps because he did not practice alchemy so he did not announce it like the other items. The elf was far more excited for minerals and gemstones.
Not just this but the two of them also came across a few essences.
While the elf didn't seem to particularly care about any sort of blood essence, he lapped up all of the elemental essences that he could get, once again absorbing these in a different crystal.
Lastly, there was also another type of essence that they came into contact with in a couple of places but this information was only privy to Liam as it was the black dragon sword that had swallowed up this essence and not the elf.
