When playing Final Fantasy XIII-2, I had an awful time locating the Wild Artifacts to open all gates. Thankfully, you don't have to have a hard time because this list exists! Here are some short descriptions on how to obtain all Wild Artifacts so you can open all gates.
Open up your map to see which zone you currently are in. This will help you locate the artifacts.
Wild Artifact 1 - Bresha Ruins 005 AF
You can get this Wild Artifact right after the tutorial in the first area of the map. Use the "Moogle Hunt" a bit to the left of the gate in the south of the Echos of the Past zone of the map. If you need additional help, looking for the Chocobo in the area to the left of Chocolina's shop. You should be using the Moogle Hunt near that Chocobo. If you fail to find it the first time, move a bit and try again.
Wild Artifact 2 - Bresha Ruins 300 AF
You need to complete the phased out NPC's quest to get this. You can find him in the graveyard area - in the top-right portion of the map. This sidequest is known as "Iridium Ring," which also grants you a fragment.
To find the man, look for the outline and use the Moogle Hunt ability. Speak to him and he will ask you to find his friend. Locate his friend in the tunnels to the southwest of the Echoes of the Past. Speak to him and select the following three puns:
- A job as a shoe salesman would be your best fit.
- Need an ark? I Noah guy.
- Salt merchants are movers and shakers.
Return to the man and he'll reward you with a fragment. The Wild Artifact will also appear in his place.
Wild Artifact 3 - Oerba 200 AF
You have to have the "Moogle Throw" ability to get this item. So, if you don't have it, visit the Sunleth Waterscape 300 AF and get it! You can also only get the artifact after completing the third Temporal Rift in Oerba.
The thing to be said - this is one of the best hidden items in the game. It is hard to explain where it is. Look for the Oebra bridge. You cannot go on the bridge, but you want to be standing in a squared-blocked off area. You can sort of see the bridge if you look to the north. There is also a piece of "broken" bridge. You cannot access this, either, but under the broken bridge, there is a ledge. Get as close to the ledge as possible, to the left, then use Moogle Throw to collect it. You should see a blueish, shining object in the distance. If you need further help, it is to the side of a house, near the big tree.
A screenshot of this location will be added soon as it is very tricky to find.
Wild Artifact 4 - Sunleth Waterscape 300 AF
This wild Artifact is near the center of the map. It is on the east side of the Animal Trail and you have to use Moogle Throw to get it. This means riding on the large animal until you get this. Keep throwing the Moogle at items and you'll eventually snag it.
Wild Artifact 5 - Archylte Steppe ??? AF
Okay, first off, you need to be able to get to the Clearwater Marshes area. When you first visit this place, you probably won't be able to. I recommend you get the improved jumping skill in Serendipity, by turning in fragments. With this, you can jump right into the Clearwater Marshes area.
To get it, head to the northwest edge. Look for a cliff at the edge. All you need to do is locate it and then use Moogle Throw to get it.
Wild Artifact 6 - Augusta Tower 200 AF
Find it on the 50th floor. It is found on an inner walkway on the west side of the floor.
Wild Artifact 7 - Academia 4xx AF
This is another easy one to get. Just find it in an alley on the southeast portion of the map. It'll just take you a lot of walking to get to it is all.
Wild Artifact 8 - Yaschas Massif 100 AF
You have to do two things: 1. Solve the Rubies of Grief Quests and 2. solve the Temporal Rift. You have to complete ALL of the Rubies of Grief quests before you get the Wild Artifact. This can take a bit of time, but these quests are really easy. Just speak to all the Rubies of Grief and get the quests in order. You can find all the items in 100 AF. The last quest, Book of Shambala, will lead you to the Wild Artifact after you complete the Hands of Time puzzles.
Wild Artifact 9 - A Dying Wold 700 AF
You have to complete this location in the storyline first. After you do, go back and visit the Farseers Relic. Examine it and the Wild Artifact will appear.
Wild Artifact 10 - Serendipity
You have to purchase it in the Casino for 10,000 coins. Play some slots and rack up some coins or just purchase tons with Gil!
