Phantom Celebration Day

20.

edit: To elaborate, after reading the below post - I think you can get it at level 1 if you relog. But at level 20 it'll give it to you without having to relog. Those are my experiences with these Hot Day boxes, anyway.

13 was the minimum last time. This is what it had to be for the Jett box. I did it on 8 Jett characters. They seem to have improved it for Phantom, though. I didn't have to relog to get it. I just had to change channels.
