Shulk
Right:Colony9. First, when you need to get the "Little Captain" quest, bring her the shield which is located in Colony6 map. (well, that's what I did, but maybe the sword from Satorl marshes works fine too), she will disappear from the colony. Later go talk to Miller at around 6AM, he will ask you to search for her in another map. Go to the Mine, she is located in the rest room where you find Otharon. Talk to her to unlock it.
Left:Colony 9. May require 5 stars. Talk to Désirée (french name :/) near the Ether's generator near 9PM. Talk to her a lot of time until she asks you to choose her job for her. Both choices will unlock the skill.
-If you pick military, the other soldiers like her (if you talk to them), but there's nothing changed in the relation's graph.
-If you pick sculptor, Betty will be jealous and you will have a new quest to make everyone happy. You will have a new connexion in the relation's map. I think this choice is better.
Reyn
Right:
Requirements: Col6 completed. Invited Hoko (nopon village), and a Hayente (Alcamoth, can be invited before Bionis awakening).
Complete the Quest from Hoko to make a better food.
Then talk to Rosaelle with Reyn, she wan't bad food again. Talk to Hoko and bring him the ingredient. Talk to Rosaelle again.
Left: At Colony9, go to residential area, just after the entrance bridge, you have three kids playing. Two human and a Nopon. You need to complete all quest so they are good friends first. Then they ask to talk to a big guy only. You need to go to Tephra's cave beat Lv95 monsters ! (I'm level88 and it was not too hard). (After Bionis wake, go to Satorl to fight apes if you are 70s, and then go to Alcamoth for 30k exp per enemy if you are 80s. you'll win 10 levels easily)
Sharla
Right: Go to Frontier Village, at the floor where you meet the elder the first time, with the light in the middle. You need to complete all the mission from Rasha and her nephew Cherri (Rasha and Cherri in French, I hope it's name the same in english). Rasha want Cherri to be happy after her mother's death, but Cherri is just annoyed by her aunt. At the end, Rasha ask to talk to Sharla only. Complete the mission on eryth sea (very very easy), go to bottom-right beach to kill a hound.
Left: On Colony 6, complete all the missions with the Hayente and Homz which are in love. The Homz is coming from Colony9 and always at the foot of the watch tower. After completing all the missions to keep the Hayente's father busy, and try to let him agree with this relationship, out of agreement the couple quit the Colony 6 and go to the Marshes, in the Nopon's cave. Talk to the couple with Sharla and go back and talk to the father at Colony 6 to unlock the skills.
Dunban
Right: Valak mountain. Go to the Nopon camp and complete all the missions from Dadako. At the end he will give you a mission to fight two unique monster (Power Balance).
The two boss are at the same place, just above the Nopon's camp.
Go up before sliding and jump to go to the tunnel on the other side. Once on the big ice tunnel, you will have to jump again before the end to land on the upper area. There you will have the Ant boss, and you can't find the other one .... he's caught in a spider cocoon
Left: Talk to Okto in Machina's town, after Bionis awakening. It's the kid who stopped growing. He is on the edge, by night. HE will ask you to fight 3 monsters (not unique monster, but special one for the mission). go back and talk with Shulk this time to unlock Dunban skill.
Melia
Right: The first and easier one is for Melia. Go to Eryth sea, you have to fix the Lighthouse. Once fixed, you talk with a woman at the top of the lighthouse who says that she will speak only with someone her race. So switch to Melia, read, done. You unlock "shy".
Left:
Requirement:
- You need to complete the decrypter's quest in Alcamoth before Bionis awakening (Talk to Rheos and Natehris).
- You need access to Sealed doors (check Satorl's quest from a hayente after Bionis awakening)
- Lv ~95
Talk to Thalea, on Eryth sea. She will ask you to check the church in Valak's mountains. Go there and at the end of the path check the Giant's statue. After that you have to fight a Lv99 Bulba. Go back to Thalea.
Riki
Right: Go to the floor where you can jump to the pool. You will find Dabidabi by night.
Go down and talk to Adidi, then go to Eryth sea's Island number 7 to kill Edkino.
Then talk either to Adidi or Dabidabi to get Riki's skill.
Left: First you need to 4 or 5 stars, or maybe it's dependent of the current story progress.
You need to go to Frontier village Floor 0, near the pool. Pikipi should give you a quest to find the Nopon's sage near Makna's falls. He want to be able to eat anything.
Go to the top place over the falls, take the tunnel and go out of it to the other side. The sage will appear between 1PM and 2PM.
It's all a go back and forth game : sage > pikipi. then Sage > pikipi > Sage > nopon girl at a top floor in frontier village > Sage. Sage > Fight monster in the middle island of the Makna's falls (Lv95) > Sage.
Fiora
Right: Go to Machina's town on the arm. you need to have at least 3 stars for Machina town's rank and have completed the quest "The Wilted Flower".
It's at the entrance of the town, there's a balcony with a human the night and machina the day. Talk to the human (Karlos), he will give you a fighting mission.
Left: [thanks to [member="Lucif3r"]]
Quest: "Battling the Brutes"
Level ~95 (Mobs are level 98).
Starts: Dulland - Refugee camp (Bionis Leg)
Pre-Req:
-Securing provisions complete
-The Moon book/blood of bafalgar complete
-A Flower for a Rose Complete
Hint: Start killing the godrill from the back (very easy).
Once dead, switch your party with Melia/sharla/someone else (I took Shulk as 3rd member), to kill the spider.
The spider is very annoying as each hit make you dizzy, so long range member are best, just heal a lot and cast regen with Melia whenever possible.
