Mission walkthrough
You start at the Agrabah Gate. Collect the nearby chests and Ordeal Blazon in the area, then enter the passage to the Cave of Wonders. There are four chests here, but the northwest and southeast chests contain Cymbal Monkeys, so take care.

In the Cave Entrance Hall, you will find the Solid Armor waiting for you. To keep the battle as simple as possible, try to keep your fight in one area, as a number of Large Armors will appear if you step into one of various trigger zones around the area, and they will gang up with the Solid Armor against you and your teammate. Also, take care when fighting near the debris on the floor, which may interfere with your movements and attacks. Defeat the Solid Armor and RTC.

During your first attempt at this mission, you'll be unable to reach the treasures on the high ledges in the area. Return to this mission after attaining the High Jump LVL3 and Glide abilities. With these equipped, jump onto the tip of the overturned pink and gold column below the north rise. High Jump and grab a hold of the ledge, then climb up. After grabbing the Elixir and Unity Badge, jump and Glide over to the platform beside the exit to obtain the Sight Unit.

Challenge Mission
Just use Blizzara at LV5 while equipped with a Keyblade that specializes in magic which can greatly increase the magic stat. After knocking Solid Armor down keep using Blizzara on it, but stay a good enough distance away from Solid Armor, because when it recovers, its counter-attack carries the risk of invoking the Silence status effect which prevents magic from being used.

For this one you will need a Keyblade with high attack power but without too many combo attacks to avoid accidental misses. Carefully keep attacking Solid Armor's head to knock it down, then pull a few strikes before it gets up so you can avoid its counter-attack. You should also completely shut down partner support in the Config. menu before starting this mission if you want to avoid any potential risks from Xaldin to avoid missing by accident (Xaldin's attacks don't count as misses - but he can make the boss move at unexpected times). Since you can't use Blizzard-type magic in this mission, patience is the key. Alternatively, come back after obtaining the Limit Boost and Final Limit panels and use Limit Breaks and any Limit Recharges you can equip since Limit Break attacks don't count as misses. Remember you can still make some mistakes, but don't overdo it.
