Summary
The Elite campaign is a more difficult version of the Normal mode but without sublevels and cutscenes. Enemies here have more HP and attack power, so they can deal a great amount of trouble.
All unlocked levels can be done thrice a day for twice the regular stamina cost for each run, and you can only unlock new chapters by clearing their equivalent in Normal
mode.
Apart from the regular gears and gear dots, Battle Girl scrolls, awakening gear dots, blood awakening gear dots, and Workshop's skill book dots can be rewarded from selected levels.
