I don't like that it costs XP to make things. Can you select which memories you lose when you make an item? "I learned how to bake a cake last week, but I'm going to have to learn again because I want to make an invisibility scroll"
If experience points represent experience, then I don't think they should be "spent" on anything but the character itself. I read through a few threads in the archives that discussed XP cost alternatives, there were some good ideas there.
I haven't decided how I'll handle item creation yet, but I wanted to ask the pro-XP cost crowd (or anyone who uses the XP cost rules, actually) how they handle potions, scrolls, wands, or similar non-renewable magic items (sure you can recharge wands, but you know what I mean).
It's one thing to dump XP into an item that will persist, like a weapon, or armor, but if you lose precious XP to make a potion, and then you drink the potion, where did the XP go? And why would anybody ever make these throw away items. Wouldn't you just save your XP up for permanent items?
I don't know the exact cost, but for example, wouldn't it be much better to make a ring of wizardry instead of a wand that had 50 shot of the same level spell? Sure other characters, like rouges, could then use the crafted items, but I'm not wasting my XP so some thief can shoot a few fireballs. And even in that case, I think it would be pretty rare for a wizard to trust a non-arcanist with the ability to cast spells.
The wizard had to study and research to learn these secrets. What about responsibility, esprit de corps, egotism. The whole "I had to work hard to learn this stuff, why should I give this ability to some moke who doesn't even understand the basic philosophy tied to weilding raw reality altering power."
My problem with the whole XP cost thing is: the rule part balances nicely, but the fit into the story aspect needs some thought.
Economically I think there would be no scrolls, wands, or potions at all. Or they'd be so rare that most people wouldn't know what they were. I don't want this to slide into another "XP cost alternative" thread, I'd just like to hear thoughts on non-renewable magic item creation and proliferation in the game world. I value the opinions I've seen on these boards, and I look forward to your replies.
