Rising Event

[alimdia]

You can enter at level 30, but you will be oneshotted by every single attack then - unlike a level 50 who will be oneshotted by only half the attacks.
If you are below level 50 you will also have to work harder to get the max reward from the FATEs - just like for normal FATEs.

Or join a party and you won't have to work any harder.
