Rust bogs contain a bunch of Qudzu, piles of trash, and two or three rust-eaten chests with high-level artifacts inside. They are generally surrounded by "rusty" or "rust-shrouded" terrain so it may be a good idea to scout around when you find some in case there is a bog nearby.
High chance of finding qudzu symbiotes, which are red versions of monsters with the same relation to you as vines.
