kenjib said:I don't think that minor creation is balanced based on principles of the amount of magical energy required to create stable matter or anything of that sort. The primary guiding logic behind D&D is mechanical balance. My guess is that the fear is that someone casting this spell over and over again every day for a year can make a lot of gold by selling the creations. Try several masterwork bows per day at 375 gp a pop, for example.
... which disappear after 7 hours or so.
They make the spell high level in order to make sure that the recommended treasure-per-level in the DMG is high enough that the economic impact of the spell will not be as significant - although it's still abuseable in this way if you think about it. Sure, there would be market limitations for offloading so many high quality weapons, and also the consideration of the number of wizards who have this capability, but indulge me and think like a munchkin for a minute here.
You have the words, but not the music. Minor creation is high level not just because you can fleece unwary passersby, but also because it's incredibly flexible. Stuck in a pit? Make some rope and a grapple to pull yourself out. Need to make some robes to sneak into the evil cult's temple? Done. Make a boat to cross a lake? Ditto.
I think many of the non-combat spells are also incredibly powerful if considered in a more realistic situation. The balance seems geared mostly around how important the spells are to dungeon crawlers. Charm person, for example, is a very powerful spell when you consider the full implications of what you can do with it.
Not much, unless you're high level and a minmaxed PC. Casting charm person a couple of times a day sounds like a great deal, until you realise that people know when they've saved against you -- and if you cast it enough, someone _will_ eventually make their save. If you don't want to be run out of town, you save up charm person for emergencies -- like, oh, when you're going into a dungeon or something.
Just imagine using in your real life a few times every day as you go about your business. Yikes! I find invisibility to also be very powerful - think of how in Lord of the Rings it is one of the most powerful magics in the entire story and think about why this is so.
Since when was the One Ring valuable simply because it turned people invisible?
