An option for characters to start at level 50, pre-heavensward, for FREE

[Seraph522]

Didn't you have to defeat Ultima first?

Actually, you do not; you just need to own Stormblood and have another class/job at level 50 (for RDM and SAM, at any rate; it'll presumably be 60 for GNB/DNC); I unlocked RDM before completing 2.0, for example.
