Can magic items be something other than predictable technology or not?
Here's an interesting question, and a lot of it boils down to definitions. In essence, any item that can be written down must be predictable to some extent, even if its "make a roll on this table and see what happens". An item that has the DM make up an effect each time it is used isn't predictable, but is a little too much trouble for most games.
Let's take as our poster child of predictable unpredictability the
wand of wonder. From the DM's eyes, this is a fairly predictable item. Roll the dice, get one of these results. The result may be unpredictable, but the mechanism of working it is predictable.
From a novice player's eyes, this is an utterly strange and unpredictable item. It's a great example for keeping the DMG out of the hands of the players. To the experienced player (who still hasn't seen the DMG), it is still unpredictable in effect, but a lot more of a known quantity. To the really experienced player (who has read the DMG), it's the same as the DM: a predictable unpredictability.
However, a question that needs to be answered is this: will the item get used? A
wand of wonder is very much an item that get used once or twice and then gets thrown away. It may be kept in the party longer if they're very low level (a
wand of wonder is great for a 1st or 2nd level party), but at higher levels they have more reliable technology to use: either their spells, or more predictable magic items.
We've occasionally debated that legendary thing called a "sense of wonder". I'm going to call it the "cool factor", being the number of times a player says "cool!" in relation to an item:
* Upon first learning of the item, there's a "cool!" (assuming the item is, in fact, interesting. A +1 sword qualifies. Obviously, we've moved past that point for +1 swords...)
* Upon first using the item, there's a "cool!".
* Upon first using the item in a new way, there's a "cool!"
A +1 sword really only gets two "Cool!" marks. "You mean I can hit for +1 attack and damage?" "Wow, I just hit for +1 attack and damage!" Ditto for gauntlets of ogre power and the like.
Meanwhile, an item that allows you to slide a creature 5' in any direction scores much higher. Move a friend into flanking? Cool! Move a vampire into sunlight? Cool! Move a friend out of harm's way? Cool!
Within the constraints of a game like D&D, unpredictable magic - or magic with drawbacks - really won't get used much. If a combat lasts 5 rounds, why spend two of those rounds doing nothing but watching the flowers grow with a Wand of Wonder? Predictable magic trumps that, and that's why we see the Big 6 so much.
What I think is important is magic that allows exploration of its uses, which is much harder to create.
Cheers!
