Competition
Delve's boards: everyone plays the same dungeon each day, so every run is on one scale.
More about this
First run leads: each champion's free run of the day, one try each. Best of the day counts retries, This week the best five days, All time the record and Skill the last 20 days. A bracket with fewer than 30 first runs that day shares its board with its neighbours. No prizes.
Every warrior that has come back from a run, by its record.
