Je n'ai pas encore vérifié, mais j'ai trouvé une info intéressante :
For those who don't know there is a shop with buffed up versions of the first class charms.
To get them you need to:
1. Go to the 2 cities for your initiation into your class (like for pyro its Eversweep and Triland)
2. Find and Clear the High Trial versions 5x (again depends on your class, for me it would be perseverance and intensity).
3. Go to Lumina and gather until you find High Trail of Transcendence
4. Beat it
5. Gather until you find Cave of Transcendence (shop)
I don't know if the following is accurate (its from another player), but the class charms should be:
All Crest Fees : 15000g for 1
Je ne peux pas garantir la véracité, mais je vais tester !
