Get to F17 in Shimmer Hill with Mystery Part or Secret Slab in bag and then walk until you find Deoxys. Good Luck
Buy friend areas. The last dungeon is the deoxys one
to get to deoxys,you need to get to some mountain and chase him around 4 meteors.
19 deoxys is on the the 20 (the real deoxys)
Fight him alone with friend bow
go to shimmer hill 17F[make sure you have mystery part / secret slab] and find him ps:he' very hard to recruit
Go to Shimmer Desert floor 20 and you can meet Deoxys(You must bring a Secret Slab.)
First, you have to get a secret slab. Once you have that, go to shimmer hill, 13th floor and find Deoxys, defeat him, and recruit him.
i dont think you can
No,arcus is not in mystery dungeon 1 or 2
