Well I think that at lvl 12 you're in the city and under the influence of the netherstones and the brain. You could make a storyline where the netherese magic that lingers in this place limits the powe of the normal weave. So in that perspective, we could advance in level and limit the power of high level weave spells.
I DM'd the Q1 AD&D module (Queen of the Demonweb pits). It takes place in the lair of Lolth in the Abyss, so magic and magic weapons worked differently than the players expected.
It was a murder module so I had to buff the players with some special magig items that worked there to not have them all killed too quickly. They all got killed anyway.
So you can tweak that stuff if you want.
