Majoru Oakheart said:It's possible to put that kind of thing in a wand, but not one that would be affordable by players until decently high level. Plus, it isn't INFINITE. And most players I know prefer permanent magic items over charged ones so they won't buy one give the choice. Even then, all the problem spells are above 4th level, the max level for wands.
Everytime we've had a wand that could do something cool like that, we only used it when ABSOLUTELY necessary. If we had an inkling there was another way, we wouldn't want to use charges. Plus its a balancing act, if they spend money on a wand they aren't spending it on a belt of giant strength +4.
Give them infinite ability to do it for free on the other hand, and it's over powered.
If you want to have a wand of dim door (wands are doable for dim door) at lvl 7, you will need an artificer, or pool party resources. It is *very* doable. Many people have a block against abusing charged items, but if you are willing to operate 1 "+" down, you can afford a *massive* array of charged items that more than compensates, and you can afford to renew the items when they get used up. Note that that wand is only really expensive around lvl 7, and will last till (probably) about lvl 9 or 10. By then, its replacement will be cheap. 1 wand of dim door, 1 wand of summon monster (checks SRD) III or NA II along with Speak Language (Terran) nets you virtually unlimited uses of walking through walls.
I hold that, if the ability is replicable by PCs under core rules (without abusing poly/shapechange), you really cannot argue that the ability would be broken for PCs.
(charged items are, by far, the easiest way to make your DM cry. Fireball, CL 5 is only 375 gp... almost affordably by a just created lvl 1 party thats pooling its funds, easily affordable by a lvl 1 wizard after the first adventure. Yes, you can blow the activation roll, but you can afford extras)
