As of writing, all but two Grimoires can be obtained by purchasing them with Gold from Chronicler Firandil in the Scholarium. One of them you obtain from completing the Scribing tutorial quest, and the other you obtain from completing the last quest in the Scribing questline, or by purchasing it from Chronicler Firandil on alternate characters once that quest has been completed. I'd really love to see future Grimoires acquired from other sources.
Another thing of note is that each Grimoire is written by some character in-world. The latest Grimoire, Banner Bearer, was written by Battlemage V'erissh.
Now that Scribing is revealed to the world, we can expect
any character to try their hand at writing a new Grimoire.
So why should a Companion character be involved with Scribing, and why should a new Grimoire be granted to the player via them?
Primarily, I think that having this overlap between the Companions and Scribing systems would be a good thing for this game. Players would need to try the Companions system in order to acquire a new ability for use in PvE and PvP. I think it would inspire players to try the Companions system for the first time, the way Zerith-var (one of our latest Companions) introduced many people to Tales of Tribute via his favor achievement.
Secondly, there are many interesting ideas that can be explored if a Companion is somehow involved with Scribing. For instance, maybe this Companion uses a version of some existing Scribing abilities in combat; maybe they even use a version of this brand new ability that they give to players. While it may be infeasible to actually adapt the Scribing system for the Companions system, it would at least be possible to make a few Grimoire configurations into standalone spells that this Companion can cast. Plus, maybe this Companion's Keepsake would give players an increased chance to find Luminous Ink? Regardless, this Companion would be credited as the author of a Grimoire, making them a noteworthy character in the canon of Scribing, and it would be cool to adventure with such an important character who has made an impact on the world outside of their questline.
Finally, there ought to be more ways to acquire Grimoires than just buying them from Chronicler Firandil in the Scholarium. Would the Mages Guild sell Grimoires for "Criminal Act" skills, for skill lines like Werewolf, Vampire, Dark Brotherhood, Thieves Guild, or Legerdemain? I don't think they would, but it makes sense that a Companion who is affiliated with those skill lines
might teach that sort of magic to the player. Even Zerith-var's offer to show the player a different approach to necromancy could've been interpreted as a segue into such a feature:
That's not to mention how interesting it would be for Companions of the same Class as the player to teach them new Class Grimoires. There'd be a reason to be a Necromancer traveling with Zerith-var, a Templar traveling with Isobel Veloise, and so on.
So, in summary, Scribing Grimoires are currently trivial to acquire. I would like to see more interesting ways to acquire them, and I think some level of integration with the Companions system would be an interesting direction to take for both systems. Even if it's just one Companion who is the author of a brand new Grimoire, that Companion would be noteworthy for players who don't usually use Companions at all. What do you think of this approach to introducing a new Grimoire?
