Tunings are the "weapons" in this game and you can change them at Lyle´Studio for 200G.
Every of the 7 main game charackters have 13 tunings and the 2 refrain charackters
there are a few things to do to get them all:
- When you level a tuning to 30 you get 3 new tunings. So do this with 1 tuning for every charackter.Liselotte sells a aspect (Skilled Tuning) for 40000G that make leveling a tuning faster.
- You can buy special sigils by Lislotte for 10000G each that gives you with a bit of luck a tuning as Special Reward. The sigils are Imperial Blade, Bullet Witch, Magician Knight, Shining Princess, Shining Priestess, Beowulfs Revenge, Berserker Blade, Imperial Ninja, Magiclans eys and Dragonshift (not 100% sure anymore about the dragonshift sigil because after you get the tuning from the sigil you will only get scores from it).You can play sigils in Alfriedes Grimoire.
There is a save point next to Alfriede so if you want to save some money you can simply save befor you play a sigil and if you dont get the tuning as special reward just load your save and play it again.
- You get tunings by completing Ferandos quests. heres a video that shows what to do for each quest:
EDIT: Thanks to an annoyance for rembering me on that one:
- After you are done with the main story and start the post game there are some level 100 monsters in the world. You get a tuning form every monster after defeating it. For the locations of the monsters see the guide for the Requiem for the Enemy achievement.
After you finished with all of that you will get your achievement.
