When the next major Blade & Soul patch arrives on June 19th, Skyforge and Shadowforge weapons are getting cheaper to upgrade, so players getting ready for the upgrade might want to hold off for a little while longer until the costs get cheaper. Of course, the patch is also introducing the new Thornbreaker weapon, along with a new type of belt with two upgrade tracks and new souls for upgrade purposes. Your max-level character is going to get that much more powerful with the changes.the rewards for daily and weekly challenges are getting improved to reflect the fact that most players do already have max-level characters kicking around, and there are also special bonuses for players who complete multiple challenges in a given time period. Hooray for better rewards! Although you’ll have to wait a little longer for the full patch notes.
