Rustung (Nexomon) · Nexomon: Extinction Wiki

When it appears

As a tier-3 Nexomon, it only turns up in the grass after you beat Ross and Nora in Laboratory Ruins Boss, or from the start in Custom Mode with high-tier encounters allowed.

Capturing

Its favourite foods are Pink Pecana, Green cake and Baguette, Rust's, as every stage of a line shares the first one's. Feeding it one adds 15 to your capture chance, where other food adds 5. Catching a Nexomon explains how the whole chance adds up.
