Old God Specimen Jar

Old God Specimen Jar can be found on the corpses of all creatures in Korthia, more likely on rare and rare-elite enemies (for Conquering Korthia), and inside other Relic Fragment-containing lootables around the zone. Turn the item to Archivist Roh-Suir at the Reliquary of Remembrance of Keeper's Respite for 150 Cataloged Research and 75 reputation with the Archivists' Codex.
