Apparently this particular craftsdrow can take the existing Ring of Wizardry she has in stock and sort of peel off the magic and apply it to Belmarniss' ring, which is much quicker than making a whole new enchantment!

The Tome is just a Tome of Clear Thought +2, nothing special except for how it is extremely special.

Can Belmarniss watch the peeling process, that sounds FASCINATING.

She totally can! The craftsdrow is very proud of the procedure, she invented it herself, it's almost as hard as making a whole new item but it's so convenient for consolidation. Peel peel peel.

That is SUPER neat, if Belmarniss ever picks up magic item making she will try to rederive it but she has no immediate plans to compete with this person.

And then Belmarniss' ring is of Wizardry!

"Thank you!"

And she will read the Tome.

The Tome is kind of boring actually? Self-help-book-y. But the feeling of her available brainspace expanding probably makes up for it.

She wonders if they HAVE to be boring or if it's just that they're written by wizards and not authors and don't have to be good reading for the magic to work.

This information is not specified in the text!

     About half an hour after she's done with the Tome, a lantern archon appears unto her hotel room and wobbles attention-gettingly. "Hello! I am relaying the Seer's instruction to please meet her in the central temple for a war council!"

Jojo looks up from his meditation and smiles at the archon. "Thank you! We'll be there directly."

     "You're welcome! This is very exciting!" the archon says.

"Awww you're cute," Belmarniss tells the archon.

"This is true!" the archon says happily.

The Seer smiles at Belmarniss and her party as they enter the temple. "Welcome, friends. I hope you are prepared for the coming battle."

"We hope that too."

Valen nods approvingly. "We're as ready as we'll ever be... and hopefully, the preparations we've made will be enough. Now, I wanted to talk to you all about your positions in the battle. This isn't going to be a protracted siege - Lith My'athar is highly defensible, but with this much magic in play, it's infeasible to seal every crack in our defenses so thoroughly that no one gets through. What we can do is keep our fortifications sturdy enough that the bulk of her army can't get through. To that end, Garrus, we want you on the battlements. You'll be supported by other archers, but they won't have the kind of skills or equipment you do."

"Very few people do. I'll do it."

"Good. Deekin, your abilities are ideal for a support role. We're going to start you on the battlements supporting the archers, but we've contracted a couatl -" he nods at a nearby winged serpent "- who will serve as a mount and companion caster, and she'll keep you circulating around the battlefield to provide assistance to the troops wherever it's needed. Is that acceptable?"

"Deekin great with that! Nice to meet Miss Couatl."

The couatl makes a shimmering noise somewhat like laughter.

"Jojo, your mobility and damaging capabilities are invaluable in the field, and to be perfectly frank, we are likely to need you in half a dozen places at once. We cannot predict where the Valsharess will send those strike teams that make it through our defenses. However, we have conjurors who can teleport you around the city. Your task will be to strike down invaders wherever they may appear."

"Straightforward enough," Jojo nods.

"Finally, Belmarniss -"

"- must stay by my side," the Seer says smoothly. "Her presence will be essential when the Valsharess comes. I do not know the means, but I know that we must not waste her energy on the battlements."

Valen sighs heavily. "I will not countermand the Seer... even if we could, in fact, use more arcane power on the battlements."

"...where's this information coming from?"

"Eilistraee has told me, countless times, that you are the key to defeating the Valsharess - and that you will be needed after, countless times more. I do not know precisely what she means by this. But I know that it is written in the annals of Fate."

"I wish someone had told me I was not going to be fighting in the main event before I prepped spells. I guess I could paste longish buffs on people who want to swing by while I'm cooling my heels in here."
