Map Help?
Forum-Index → Help → Answered → Map Help?BUT the maps have a type requirement. Let's take the "Marine Cave" for example. As it is a rumble mission that happens under water, you have to send a Water-type Pokemon.
(I can't test this right now because I currently dont own any Maps, but it is very possible that the legendary maps will only appear in the "special Area" selection, when you have selected a Pokemon of the appropiate type)
The wiki has more precise information on which types are needed for which maps.
