The first line in Reward is the scaling roulette reward. It's only available the first time you complete that roulette for the day, and meant to compensate you with extra experience or tomestones for running content that is below your level. These reset at JP midnight / 0700 PST / 0800 PDT.

The second line is Adventurer in Need. These are available as many times per day as you care to sign up as the listed role.
