The letter also revealed that PvP will be changed to have specific job layouts for PvP, with a small selection of traits and abilities replacing the existing system of PvP ranks and improvements. Players will also have access to jumping potions starting on June 16th, with one potion allowing you to level a specific job to 60 instantly and another allowing you to flag all of the MSQ as cleared up through Heavensward. Both will cost $25, so you can use them to speed your way to being ready for all of the new tricks shown below in Stormblood.
