The Battle Castle is in the south east of the Battle Frontier. The method of battling within this battle facility is that unlike the other facilities, your Pokémon do not get healed.

As usual, there are three different selections you can go in with; Single or Double Battles & Wireless Mixed. Single allows for 3 on 3 and Double allows for 4 on 4. So if you have teams primed for each particular aspect, then feel free to use your prime selection here

Once you've made your Pokémon selections, you can go on through where you get greeted by the Butler. Whenever you win battles in the battle castle, you earn Castle Points. As you cannot heal your Pokémon, you can exchange the points here for certain perks for use only within this Battle Facility, heal your HP, PP or get an item. The better choices are worth much more Castle Points so its always best to save. The items you buy and the rank ups remain throughout your streak so you do not have to keep doing it after every 7 matches. You CP total also stays throughout your streak.

The options for your own Pokémon are as follows. You also have the ability to check you're Pokémon's current stats, hold item, HP & PP in this screen;

There is also an option for you to to attach items to your Pokémon for a C.P. As items are removed from your Pokemon as you go in, its good to get these for your best competitive strategy. First here are the rank ups for the Items & Berries combined;

You also have the opportunity to see your opponent's Pokémon and the specific stats regarding them. They also cost and are as follows

Once done, you go in and battle away. Like the other Battle Facilities, they are done in streaks of 7 before you can exit. Try to get the best streak you possibly can.

Once you reach a streak of 21 in the Battle Castle, when you go to have your 21sth Battle, you will be challenged by the Frontier Brain of the Battle Castle; Darach. His Pokémon's level match your own. The team he has is not the strongest you will face, but based upon your past battles, if you do not spend CP to heal, you will struggle. Beat him and you get the Silver Medal

Continue in on the streak and continue to beat all the Pokémon. Now you have the option to skip battles for 50CP, you may be able to get through it even quicker, should you earn points wisely anyway. As always, the trainers get stronger so you have to be prepared. Once you hit your 49th battle, Darach will re-appear. Beat him to get the Coloured Medal
