Plan bases by job
The useful question is not only how many bases are allowed, but what each base should do. A starter or main base can handle storage and early crafting, while a second base can focus on mining, oil, breeding, or raid-safe storage once that bottleneck becomes repeated.
Check the current limit in-game
Base limits can depend on progression and current version rules, so confirm the live number in your game before moving rare materials. Use this page as a planning framework, then let the in-game base interface decide whether the next Palbox can actually be placed.
When a new base is worth it
Build another base when a repeated route is wasting time: Ore and Coal trips, Crude Oil extraction, Cake production, or defensive storage. If the current base only has one awkward station, fix the layout first; if the same resource problem repeats, a specialized base is usually cleaner.
