Enjoying the summer is more fun when you have friends (or at least a crafty merc!) by your side. From Thursday, July 2 through Monday, July 6, there’s a Marketplace sale to help with just that. Both Merc Crates and Group XP Potions will be on sale for 40% off!All Access Members will get their additional 10% off the sale price.
And as an added perk for All Access Members, it’s a Bonus XP Weekend! AAs, Tradeskill, and Adventure XP will all be doubled.
