So, my Inquisitor has gone from 1st to 2nd level. I know some things change on the spot (BAB, saves, HP, skill points) but I need some answers on spells.
He now knows 3 different 1st level spells. He can cast any of these 3 times per day.
I assume that he must rest for the eight hours in order to learn the new spell. However, does he gain the extra casting per day immediately, or does it also need rest before it activates?
Sorry if it is a noobie question.
This is not explicit in the rules.
Some GMs allow you to "ding" like the MMOs and CRPGs, you instantly gain your new abilities when you have enough XP for your next level.
But most GMs don't. I think it's fairly common to expect you to get a full night's rest before being able to use spells/slots that you were unable to use when you woke up this morning.
Me, I expect the PCs to spend a day of downtime training their new stuff (which also means they can't do it in the middle of a dungeon). This has multiple benefits, chief amongst which is that nobody levels up in the middle of an adventure I planned for their current levels.
In short, ask your GM.
Are you asking because your like in the middle of a dungeon, just leveled up, and have another encounter for the day? This arification may help some people answer.
Yeah, not explicit in the rules. In my experience, most GMs don't give XP until the end of the session, so players can do their level-up procedures between sessions. Or they simply don't give XP, so they can announce the PC level-up at whatever time is deemed appropriate.

That is the exact situation. We know there are baddies in the very next room waiting for us to come in.....or, if we take too long, will come bursting out in a few rounds.
So, I will ask our GM to houserule it if there are no hard rules on it.
