I’ve added this to the OP:
Brann will keep his level going from Season 1 to Season 2, and Brann’s level cap will increase to 80 in Season 2. When Season 2 begins, we’re adjusting the experience required to level up Brann, making it quicker to progress up to level 60 if you haven’t gotten there yet.
Your Coffer Key balance will be reset. Keys cannot be carried over from Season 1 to Season 2.
