So you are deliberately ignoring valid reasons to go to remote places. Why? So you can win the internet?
You called me disengenious for not agreeing with my post from the DMG. I told you I did not post that, that I had never seen that.
You decided to respond that you agreed with whoever had posted it...
Well great, wonderful for you. Still wasn't me, so I'm left wondering why you decided to accuse me of something. So yeah, still waiting for an explanation here. Whatever other reasons wizards might go out to remote places has nothing to do with your accusation.
Then, because I tend to try and respond to the entirety of a persons post, I addressed your points. Not ignoring them at all. So, that is two false accusations.
They would have food, the supply most in need at that point.
That might be the thing they are least likely to have a surplus of. A remote mountain village might not have enough food to feed an additional team of people for a month. Storing food is a difficult process and they would likely be cutting pretty close to what they need for themselves, not having excess for travelers who would rarely show up anyways.
Just because I don't want to type of the literally dozens of easily thought up reasons, doesn't mean that they don't exist.
"Just because I don't feel like defending my point doesn't mean it isn't defended." is again, a poor position.
But alright, I refute those dozen reasons. It is pretty easy, I just don't feel like typing them out.
For items. Potions are explicitly enchanted herbs, waters from sacred places, etc.
The DMG does not make any distinction between items and potions, no enchanted herbs or special water mentioned either.
Feel free to quote the page where it is though, I'd like to mark it since I generally find the DMG crafting rules severely lacking
