Siliconera found out the details on this limited-time event before but the precise dates weren’t revealed until now. So here we go: the “Flames of Vengeance” challenge event runs from September 17th until September 30th.
That means you’ve got until the end of the month to unlock and recruit Thancred and Y’Shtola, Scions of the Seventh Dawn, from Final Fantasy XIV, and find their Memory Crystals. You unlock them by beating the new dungeons in Eorzea.
There’s also a new accessory. It’s a three-star Ruby Ring that increases Attack by 15. You can put it on Thancred or any other physical damage dealer in your party.
