Secret Bases have finally made a return after 12 long years! Secret Bases originally were a concept in Pokémon Ruby and Sapphire, and much of their functionality remains: that is, you can decorate a personal secret area and also battle other people with such areas.
Of course, with Omega Ruby and Alpha Sapphire, this functionality has been expanded in many a way.
Creating a Secret Base
Still, the basics are quite the same. When you reach the northern part of Route 111, past the Fiery Path, you’ll meet up with Aarune. This man will give you the TM for Secret Power .
Secret Power is a move that has its own uses in battle, but it also has a particular functionality in relation to Secret Bases: that is, the creation of the base at a Secret Spot.
Secret Spots are found at large trees, large bushes with a small hole in them, and mountainsides with a small alcove in them, as you can tell to the right of here. Simply have a Pokémon knowing Secret Power in your party, then examine the spot and opt to make a Secret Base!
Note that you can only have one Secret Base at a time, so if you have one already you’ll automatically clean out the old one when you make the new one.
Your Secret Base
Inside your Secret Base, you can examine your PC for a number of functions. In particular, you can decorate your Secret Base with a number of items, though you can only have so-many before you cannot add any more. You can also delete old bases and organize team data.
You can also save a QR code, containing your Secret Base data, to your 3DS/2DS such that you can share the code through various means and let people scan it with their 3DS/2DS to add your Secret Base to their Omega Ruby/Alpha Sapphire.
Of course, you can do the same yourself and scan QR codes shared by other people. In fact, some special bases can be found only through QR codes distributed by Game Freak or Nintendo, and in those cases the southeasternmost house in Mossdeep City will house them.
Other Secret Bases
You can receive other people’s Secret Bases in ways other than QR codes. StreetPass is one method. You can also receive them whenever you’re online from the first 30 people with one to go through your PSS’s Passerby list. When you visit one of their bases, there’s more to do besides just gawping.
The player may also be in there; speak to him or her and you may receive an item. Afterwards, you can opt to battle them: their party will consist of up to 3 Pokemon they had during their last visit to their base, and their levels may be limited unless you activate the Level Release in their base.
You can also battle their Secret Pals (the other people) and add the main player to your own Secret Pals. Secret Pals can be battled in your base once daily and they can use a number of powers (to be enumerated later): you have up to five such Pals, or less if you have removed some Welcome Mats from your base.
Finally, when in someone’s base, be sure to snatch up the flag next to their PC: by collecting flags, you can unlock more features. Each base yields one flag once per day.
