“The Riddle of Steel is not part of the four core DLCs Funcom have planned for 2019 and will therefore not be included in the Year 2 Season Pass. Instead the studio has simultaneously released a free update, which includes two new dungeons, a total revamp of several locations, new NPCs and a new feat, Witch Doctor, allowing you to summon wights and skeletons to your side.”
