About Ladder Hall -READ-

Also, I've spent some time looking around for information about if you keep ladder only items after the ladder season ends, and I have found nothing. But, if you could, then they wouldn't be ladder only items because you would then have them on non-ladder characters.

Do I get to keep my Ladder Only Items when the season is over?
A: Yes. Any Ladder Only Items will be converted over when your character is converted to a Core character. These items can now be traded with other Core characters. That is the only way for Core characters to get ladder only items, as leftovers after a season is over.
