Belmarniss shows up early the next morning for her consultancy meeting, munching a pastry from her breakfast spread. "Hey - I was told to meet with a Luay?"
"Super bizarre! At least it didn't short me an odd numbered level? I guess? But what a ripoff!"
"Betcha someone in Sothis might have a guess, if you ask around. Mahdi might know."
"Still wanna sleep the night here. We could re-pace or go from where we're at, what's your pleasure?"
So they repace and she loses even though she has more Admonishing Rays than she thought. She wakes up a bit later covered in sand, and giggles softly.
He is leaning right over her and quickly steps back away. "I just - had a cure spell if you needed it -"
"Eh, save it in case something sneaks up on us in the night." She gets up, going 'oof', and tromps over to her mercifully already-set-up bedroll.
Zzzzz.
And they can be back in Sothis in plenty of time to snag the other two for lunch and ask Mahdi about mysterious sorcerer levels.
"Haven't heard of it. There are ways to chain your sorcerer and wizard caster levels but I think you still level in wizard when you do that?"
"So your overall caster level takes into account the sorcerer and wizard levels. I haven't done it, but I read something about it somewhere."
"Fly lasts longer, but I thought that was just normal progression... haven't precisely timed it, I was expecting more wizard slots."
"Huh! I don't remember any more than that about what chaining the levels involves or how it's done or anything, I'm sorry. I'd be surprised if it interferes with getting fourth-level spells? Because people did it deliberately."
"I guess not having to ration my admonishments is nice but there had better be some cool upside in the works."
