I'm sure that sooner or later, players are going to start asking their DMs if it is possible for them to research the formulae or "recipies" required to craft specific magic items. Maybe a player would really like a flaming longsword for their character, or what have you.
How do the DMs present think they will handle this? It seems like a reasonable request, similar to researching new spells. But it could have the potential to unbalance a campaign by allowing in items that a DM would prefer not to include in their game (for example, a decanter of endless water in a Dark Sun game, or a "key item" that opens the door for some particularly obnoxious powergaming -- but old school DMs may argue that I repeat myself).
Well? What do you think?
I had a player leaning toward this last night. I think he wanted to use the Forge of Spells in the Lost Mine of Phandelver to start making his own stuff. I told him he needed to be a dwarf master smithy to utilize the magic for permanent endowment of magic. Otherwise it would only be temporary and fade. I don't want them accessing the ability to make permanent magic items like that at all, so I just won't allow it. I prefer to think of such things as "ancient from another time" when magic worked differently than it does now.
