How bags how the druids fund their conservation programs. Planting rust monsters and then getting paid to remove the rust them
Yeah, I'm coming around on this - I guess the whole reason they rust things is to eat the rust, so iron ore would basically already be in edible form. Much of it is still solid rock though, which is why they prefer to go for the refined metals that they can easily break down into powdery rust.
I kind of want to run this in a system where the players can't just all build monks to get around these issues. It'd be fun in Shadowdark, where the PCs probably won't die (unless they run into something deep in that requires weapons to deal with, once their best weapons are gone), but which will require a lot of out of the box thinking.
It would be hilarious to have the equivalent of an Alien movie, complete with corporate jerks looking for military applications, but using rust monsters instead. Most of the franchise provide game-ready plots to do just that.
Well, now I have an adventure for my current campaign...
Remember to save turning one of the PCs into a human-rust monster hybrid for a later adventure.
