When Techland released the Hellraid DLC in August 2020 inspired by their unreleased dark fantasy slasher Hellraid the reviews were not kind, as it was very basic but they've kept at it and another big update is out now.
"The aura on the other side of the portal is changing… As Lucius’ lost ancient power was flowing through Hellraid, awaiting an adventurer who could tame it, it has found a new vessel. Prove your dedication and mastery of your skills to get hold of that raw magic, and you’ll grasp might beyond understanding. Are you worthy of holding the Fire Wand, the weapon allowing you to command flames themselves? Enter the hellish dungeon, and face the trial."
This fresh free upgrade brings with it a new map section to explore, a new skill that gives you a Fire Wand, three new potions and you will also be able to access an armoury when you finish the imprisonment quest. They also list "minor tweaks and bug fixes".
