Seed Bracelets
— new Seed Bracelets have been added to the game;
— existing Seed Bracelet, that was available via Special Game Assistant (ex. Dimensional Merchant) in exchange for 20,000,000 Adena, is automatically replace with Elementary Seed Bracelet;
Not only the cost is completely different from here, the patch notes always differ at some point as they have completely different way of making money. There they dont get adena or drops without vitality, but they get 2x xp with their version or prestige pack.
They can get brooch jewels in game, while we cant.
Sometimes they even get different cut points from what we get.
EU patch notes cant not be trusted for NA updates.
