Gem fragments can now be transmuted to form Gem fragments of another type. This process requires you to transmute three other Gem types in order to craft your desired gem.
You can craft summoning items needed for Echo of Varshan in the Alchemist. This would require you to exchange other Varshan summoning materials and convert them into any of the other materials, except for Malignant Hearts.
You can now also craft Obducites in the Eternal Realm by using your leftover Ingolith and Neathiron, which were previously obtained from The Pit. As of Season 6, Ingolith and Neathiron are no longer obtainable materials.
