They are in places at sinnoh,but all of them could be found underground
There aren't any plates in Pokemon saphirre and ruby
No
You can get some plates from the SS. Aqua captain
No, plates will not increase the attack power. Plates determine what type attack Judgment will be.
No
18, one for each type
pfft i love pokemon
The plates are not an optional part of the game, but they can power up certain Pokemon's moves and change the Type of Arceus and his exclusive move, Judgement.
this is the same as Pokemon platinum, they are in the underground, they do take a while to find.
arceus because if you have plates you can change its type
None. Plates are used for 2 things: make Pokemon of the same type stronger and change Arceus's type.Also, it is thought that you take the plates to the crogunk statue in pastoria city and in seeps an azure flute
That'd be Arceus.
