This is a homebrew variant of the archivist that adapts it for use with the Eberron: Rising from the Last War artificer.

What are the best ways to store vast amounts of information? That question has occupied chroniclers and librarians for centuries. Scrolls and books were the finest information-storing methods for a long time, but the first Archivists imagined something greater: storing information in a real or an artificial mind. What library could match a mental archive capable of accessing information in seconds? As they work towards this goal, Archivists have become masters of storing knowledge and creating artificial intelligences fueled by magic. These techniques have yet to be perfected and institutionalized, and of all artificers, archivists are on the cutting edge of arcane science.

Starting at 3rd level, you always have certain spells prepared after you reach particular levels in this class, as shown in the Archivist Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Artificial Mind

At 3rd level, you discover how to awaken a mind inside an object. Whenever you finish a long rest and your calligrapher’s supplies are with you, you can magically rouse a keen mind within a Tiny, nonmagical object on which you write mystical symbols. The object is a magic item while the mind is inside it, and you can use it as a spellcasting focus. If you already have an artificial mind from this feature, the first one immediately dissipates.

The magic item has the following properties.

Telepathic Advisor. The artificial mind telepathically supplies you with advice and information about certain topics: while the item is on your person, you have proficiency in two skills specific to the mind; see the Artificial Mind table for more details.
