Heroic Races: High Score
In Heroic Races: High Score you can win the following rewards.
The Pool size is the max number of items you can collect until more spawn, and the pool starts out full. 1 spawns each Wait time. So if you empty the pool, then Pool * Wait later it will be full again. If "Time" is listed as "No Minimum" it means you should be able to complete the mission with no wait due to the Pool. There may still be wait due to Fight timers though.
