In one of my campaigns I have a character that just leveled up. I've been planning for a while to multi-class into Wizard, but never really had the character RP prepare for the event, since I didn't expect to level up mid-dungeon (we're using milestone XP). I always figured we'd end the dungeon run, head to the nearest inn, and I'd be able to level up and prepare there - buy the spell book in town, and so on.
We're nowhere near done with the dungeon, so I'm not going to buy a spellbook anytime soon. I'm looking for creative options to get around this hurdle without having the party wait for this guy over here to prepare his book. Thus, my question is two fold:
- Can I immediately just use the 3 cantrips I've selected?
- What would be a reasonable approach to scrap together a prepared spellbook, having no prior scrolls and no spells?
So far I've written a short story for the DM explaining that my character "secretly bought an empty notebook a while back (subtract whatever GP is appropriate)" and that he's been "observing the other spell casters in the party" and wanting to get into magic, but "it wasn't until the last battle it all clicked for him."
Not sure if that's going to fly - and honestly I'm okay if it doesn't. I want to be realistic within reason, but I also feel like there's a compromise to keep things fun. Could my character overnight just suddenly unlock a prepared spellbook? Would it be more reasonable to craft one, and then during each rest slowly build up the prepared spells?
