After making a pact with Volt, you can get devices that allow you to travel anywhere.
In Euclid, go into the northwest house and talk to Stanley downstairs to get the Airbirds. Now you can go anywhere!
First, go to Alvanista, which is east and slightly south of Euclid.
Talk to the elf at the middle south entrance of Alvanista to learn about Aska.
If you race the kid, choose the S-Flag, which revives a fallen party member with full HP. You can win three times.
Enter the castle. After the cut scene, fly southeast to Olive Village.
Buy Eggs from the guy between a house and the item shop. You can sell them for a good profit.
There is a strange grave to the right of the weapon shop. Check both the front and the back.
Go to the oasis nearest to Olive Village and talk to the guy to learn a new skill.
Go north to the White Forest and gather mushrooms. They are all in the same places as they were in the White Forest in the past.
Fly north until you see a small island, then fly west to Ary. You will know that you are in the right place if the sky turns dark.
Talk to a woman in the pub to buy a new skill. Talk to a soldier in the pub to get a Dedis Emblem. Talk to the woman in front of him, who is standing behind a plant, to learn of the Ninja Village.
Go up in the Airbirds, then turn north-northeast (mostly north, slightly east), then go past Treant's Forest, until you see Edward's house. Land there.
Check in the bed upstairs for a Drum Set. If you go to your inventory and use the Drum Set, you can use the controller to play drums.
Go up in the Airbirds, then turn north-northeast (mostly north, slightly east), and go in that direction to Freezekill.
Go into the weapon shop, use a Rune Bottle on a Charm Bottle, and use the Lotus Perfume. Then buy a Laser Blade for Cless/Cress and a Holy Rod for Mint.
Then go to the Inn and talk to the guy in the far left room to buy a new skill.
Make sure that you have at least 110450 gold before you go there. If you don't have that much gold, you can buy eggs in Olive Village from the man between the item shop and a house, then sell them in any shop for a good profit.
In the ocean south of the Freland dock, there is an island where you will find Aegis's Workshop. Use a Lotus Perfume and buy one of each Rare armor for Cless/Cress, but don't get anything for Chester.
The kid to the right is selling the extremely expensive Combo Command. You probably can't afford it right now, but you might to come back and get it later. With a Lotus Perfume, it will only cost 2,500,000 gold.
If you equip the Combo Command, you can press different key combinations in battle to make Cless/Cress perform certain skills, much like in a fighting game. Different people around the world will tell you the combinations. The combos are listed on the Combo Command page.
However, with the Combo Command equipped, Cless/Cress's four assigned skills will be ignored, so you can't press the usual button to perform those four skills.
The Combo Command allows Cless/Cress to use long range skills even at short range, and vice versa.
After this, you can find new pact rings and spirits for Klarth/Claus to contract with.
