Casting aside the fact that we replace our Scholars' grimoires many times as we level up and gain new gear, I roleplay Y'lyfriel as finding a special significance in one, single tome. It has a lot to do with where the tome was compiled.
This is pretty much exactly what I roleplay. Lyf's grimoire is a comprehensive collection of tactical information, scholarly expounding, and geometric diagrams for her reference when focusing aether. Much of it was written by her or borrowed from other scholars and arcanists working in Limsa Lominsa. However, this makes much of her use of magick very "modern," when compared to what the scholars of Nym might have worked with. You could weave in your character's acquisition of this Omnilex with a change in tactics and broadening of historic knowledge. Applying historic magicks to contemporary problems, for example. Or, a deeper connection to the faerie-creature he's bonded to, if that's part of your roleplay. I'm remaining a bit broad, here, so you might keep some of the specificity in how you approach this a mystery
In previous MMOs, I've always used "show, don't tell" as a way to illustrate the power or significance of supposedly "rare" items. Seeing how such an item changes your character, or changes how he fights/behaves/sings/speaks/makes cakes, etc. tends to come off as immediately more believable than a reciting of facts about that item, or how it was required (not that such knowledge isn't important; it is, just less so in the middle of roleplay, from my experience.)
