Hussar
Legend
Interesting point really. If your entire day's nutrition comes from a single berry you eat in the morning, it's not like the army is going to be pooping a whole lot. Which in turn is going to have an enormous impact on the sanitation, which, let's be honest, killed FAR more soldiers than spears or arrows ever did. Between having Purify Water and Goodberry, that's going to be the healthiest army in history.Not having to do dishes would also be amazing. But now I'm wondering about the impact of goodberry on latrine usage. Not normally something to worry about in a fantasy game, but fascinating to consider in general.
It's one of the things that always rather bugs me about D&D. So many of the settings don't really take the books into account. Not in any real way anyway. As I mentioned before, the Monster Manual would have such an enormous impact on the world. So many of the things in the Monster Manual would have huge impacts.
