Where do Nimbi spawn?

Weather is the trigger here, so a dry visit to Nimbus Fields undersells how common Nimbi are. When rain or a thunderstorm rolls in, they turn up in large numbers, and that is the time to go hunting for one or for several.

Nimbus Fields is an early zone near the first outpost, so you will be passing through it from the start of the game. Turbo lives in the same fields, which makes it an easy area to work through more than once.

Weather is not the only clock in this zone. Basic Sparki in Nimbus Fields spawns only at night and cannot be found during the day. If you are after both, a night storm in Nimbus Fields covers the two conditions at once.

Not settled: How often Nimbi appear in clear weather is not pinned down. The large groups are tied to rain and thunderstorms, and nothing here sets a rate for dry conditions.
