I got ya' last time. Like I said, I believe it's a requirement that you have been wearing the amulet for the majority of your current level, and when you level again, while still wearing the amulet, you would gain the bonus spell slots and the capability to cast spells of that level.
The capability to cast spells of a given level is not tied to a character leveling up. It's only dependant on the ability score. I don't know where you're getting that from. The only thing in the PHB/DMG I've found that refers to something that had to be on for most of the character's level to gain a benefit is the number of skills points you get when you level up. Please correct me if I'm wrong in this respect.
Back to my original question, and making it really, really simple:
I'm a wizard with Int 14. I find a 5th level arcane spell scroll, and the spell is on my class list. I cast Fox's Cunning on myself, so now I have Int 16. Can I cast the spell from the scroll?
