The main focus of the next major patch is battle improvements. The hope is to make each battle feel a little bit different through offering different battle challenges by force and player choice.
Two new features will be added to accomplish this:
Terms - A mix between missions and affixes. They each offer you a different reward. Besides the ones each battle carries by default, you can also add your own terms to battle.
Enemy Stage Change - A custom action will also be triggered based on elements when enemy shift its stage.

Since a lot of systems need to be updated to make this change happen, it will take a bit longer than usual (approximately 1 - 2 more weeks), Thanks for your patience!
