I posted this elsewhere, but Im seeking multiple sources of feed back so Ill toss this here as well. My players are in the process of getting a custom built carriage for themselves. One of them is playing a spoiled noble type char and he insists in needed for the group. Everyone seems to think its a good idea, myself included, after hearing what he wants to do with this. Think spy car in D&D, build a collapsible crossbow on top, drop grease spells out the back, a rack of magic missile wands in front, and other stuff while powered by magic, needs some engineering skills to fit into the cart (as my DM interpretation). My plan is to allow them to do this, but SLOWLY and over time, and telling them they need to get to LARGE TOWN X, where they can find a skilled gnome engineer to do all of this. My question is this: is my decision to say what they are asking for require gnomish engineer justified? And as such, what kind of time/money requirement are we looking at? Right now all they have is the custom made cart, nothing fancy right now, as they are just level 4. Im just wanting general thoughts people might have on this, as I frankly am not sure where to go with all this. My 3.5 source books are limited, but if you know any I could look through, one of my players has a quite extensive collection. Any ideas/thoughts/concerns are appreciated!
