Mideel
The town of Mideel is the next official stop for continuing the story, but now that you have access to the Highwind, there are several side quests that you can complete beforehand, many of which involve revisiting towns that you have previously been to.
Note that you may have already completed the first two side quests listed below if you have been following this guide all the way through.
Traveling to Wutai
Side Quests

A side quest that you may have already completed wherein Yuffie steals all of your Materia. This point in the game will be one of the last times that you can complete this side quest.
The Wutai Pagoda
Side Quests

This quest also takes place in Yuffie’s hometown of Wutai. It involves traveling to the Godo’s Pagoda at the back of town to obtain Yuffie’s final Limit Break, All Creation, and the Leviathan Summon Materia.
Returning to Nibelheim
Side Quests

Travel back to Nibelheim to obtain an Elemental Materia, but it will only be available if you went in to “jam” on Tifa’s Piano during the flashback sequence. More information is available in the Kalm section of the walkthrough.
Returning to Cosmo Canyon
Side Quests

Travel to Cosmo Canyon to pick up a Full Cure Materia and a Magic Source.
Returning to Rocket Town
Side Quests

Travel back to Rocket Town to pick up the Fourth Bracelet and a Guard Source.
Chocobo Sage’s House
Side Quests

Traveling to the Chocobo Sage’s House to pick up the fourth and final Enemy Skill Materia.
Purchase some Mimett Greens from Choco Billy at the Chocobo Farm before you travel to Mideel.


Lastly, considertake this opportunity to revisit Costa del Sol, as there are new weapons that you can purchase from the Weapon Shop, including:
Mideel | The “Hot Springs” Town
The town of Mideel is on the southeastern continent, and you can identify it by looking for a red dot on the mini-map (which you can pull up at any time using the button).

There is an Item Store near the entrance that sells regular items, but it also sells the following:
The Mideel Item Shop is the first shop that sells Remedy items. They are expensive to purchase, but they can cure nearly all status effects, making them quite helpful. Don’t purchase too many of them, as the
Ribbon accessories that you’ve recently acquired should be preventing you from being afflicted by many status effects already.

The Materia Store is on the far right side of the screen You can purchase the following Materia:
The Weapon Store is up the stairs on the second level, the one with the girl in the blue dress standing out front. There are lots of great weapons and armor for sale, including:
Crystal Sword
Crystal Glove
A·M Cannon
Crystal Comb
Crystal Cross
Crystal M-phone
Partisan
Winchester
Crystal Bangle
Wizard Bracelet
The lady you see in each of the stores is the same woman accompanied by the same little white Chocobo. Speak to the Chocobo inside one of these stores, and Tifa will offer to feed it the “Samolen Greens.” The name of the greens listed in the dialogue box is another typo in the game, as Samolen Greens do not exist. This typo was corrected in the PlayStation 4 version of the game, but they misspelled it again as “Mimmet Greens.”

Choose to give it some “Samolen Greens,” and you will actually feed it the Mimett Greens that you should have purchased.
After that, choose to “Tickle behind his ears,” and the Chocobo will give you the Contain Materia.

Contain Materia has some of the most powerful spells in the game once you get it leveled up. Tornado and Flare magic are on par with magic like Ultima and Comet. Contain is very good Materia to equip on any of your more “magic-focused” characters.
Inspect the door at the back of the Weapon Store to confirm that it is locked. You need to inspect the door before proceeding to the next steps.

Cross the wooden bridge on the left side of the screen, just to the left of the man in purple, and you will hear the ground make a noise as you walk over it. Examine the ground to find a “Beat-up Useless Old Key.”

Take the key back to the Weapon Store and attempt to use it on the door at the back. The man at the counter will ask Tifa what she is doing. You will have the option to either “Lie your butt off!” or “Tell them the truth!”.
Choose to tell the store owner the truth. The store owner will then hand over a Curse Ring accessory.

Curse Rings
Helpful Hint
Equipping the Curse Ring will increase all of your character’s stats, but it comes with the drawback of automatically inflicting the “Death Sentence” status, which will kill that character after 60 seconds.
You can counter the effects of the ring and prevent the “Death Sentence” from killing your characters by equipping them with an Added Effect Materia paired with either the
Odin Materia or a
Destruct Materia.
Make sure to pair these two Materia together on your Armor! Pairing them will make that character immune to the “Instant Death” status effect, allowing them to equip and use the powerful Curse Ring accessory.
Proceed to the north end of Mideel to continue with the story. Tifa will stop and talk to the dog before discovering that Cloud is in Mideel and is in the clinic nearby.

The story will continue for some time, with Tifa deciding to stay behind with Cloud in Mideel.

You will regain control as Cid aboard the Highwind. Walk over to the Operation Room and speak to the man inside.

Choose your party and spend some time equipping them with Materia, armor, and weapons. Tifa’s Materia, if she had any equipped, will be back in your inventory. Speak to the (now LV6) pilot in training when you are ready to go.

Fly back down to Mideel before you go anywhere. There was one final house in Mideel that you never had the opportunity to explore near the area where Tifa found the dog and behind where she overheard the two men talking about Cloud.
Enter the house to find a gigantic Elixir sitting on the bed.

You should also take this opportunity to purchase weapon upgrades for your characters if you need them. You have now likely had to make use of characters that were not generally in your main party, and you may not have been purchasing weapons for them along the way.
Cid’s team will soon be exposed to some battles, so make sure that they are fully prepared to fight.
