... Just out of curiosity, which spells did you eliminate? I know that teleport, time stop, and wish is at the top of many people's lists, but I'd be interested to see what you've done. ...
I can't go through a list right now, but I should have been more precise in my original post: of the spells above 6th level that I have kept, ALL have been transformed into "incantations" (using a modified version of the UA guidelines).
These "incantations" have extremely expensive costs and rare components. Some of the components needed to cast high-level incantations can serve as the bases for quests themselves. Casting times are 1+ days.
The incantation can lead to the spell being cast at the end of the ritual (e.g. limited wish), or can lead to the spell being "infused" into a special scroll that can be used at a later dater (e.g. Prismatic Spray, Energy Drain).(Costs ofsuch scolls: that of a normal "scribe scroll" + special incantation costs).
This makes 7+ level spells rare and difficult, but not impossible. (And it does note excessively affect certain spells, e.g. clone, which require long periods of time as written.)
As for magic items, I have added 5 levels to the prerequisites for all item creation feats (except scribe scroll and brew potion).
And, as some people have mentioned earlier in this thread, I have cut the frequency of spellcasters down quite a bit -- most priests are experts, etc.
The result is a "rarer magic" campaign. Magic exists, but it is rarer than it is in a normal DnD campaign, and tends to be concentrated in the hands of a few powerful individuals.
