Gottfried's Omni-opening Grimoire is a quest item in The Witcher 3: Wild Hunt.
- The Defensive Regulatory Magicon (or DRM for short) belongs to the above mentioned group of the longest-lasting, most effective and hardest to break defensive mechanisms. In order to recognize the individual administering it, it makes use of a portal mounted at the entrance of the area it is to defend. This portal passes streams of magical energy through the body of the person entering and can, in the blink of an eye, determine if this person has the corporeal signature (eyeball structure included) of the entitled administrator. As a result, the only unauthorized individuals that can possibly hope to enter are mimics.
- DRM thus makes for an extremely effective and near-unbreakable security measure - but you are in luck, for you hold in your hands the key to bypassing it, namely the present tome, Gottfried's Omni-opening Grimoire, or GOG for short. In the pages to follow you will find innumerable methods for deactivating DRM, or, even better, bypassing it altogether(...)
- This book (and its associated quest) is the developer's jab at the practice of digital rights management (DRM). While the tower was purchased pre-owned by the mage, making him the legal owner of it, he's not the tower's original owner, and thus the tower's Defensive Regulatory Magicon (DRM) locks him out of his own tower. This book (GOG) is needed to unlock the tower and is a reference to GOG.com which is a service that provides access to DRM-free games, and a wholly owned subsidiary of CD Projekt.
