Get Stamina From Missions
Help clean up the streets of Fontaine! Gather stamina by completing Daily Missions and Challenge Missions both within the web event, official fan Communities, and in-game. Daily Missions reset at 4:00 AM (Server Reset).
Challenge Missions
Challenge Missions do not refresh, and players can only get a maximum total 250 stamina from all Challenge Missions. This means that after you complete five Challenge Missions, you can no longer collect rewards from completing the other Challenge Missions.

| II. Radiant Rose The underground recesses of the Fleuve Cendre are a breeding ground for all kinds of filth...

Clean the Designated Area
Aim, Press, and Hold to Shoot Water
Enter a stage and press anywhere on the screen to enter Cleanup View. You can set your pointer sensitivity from Low, to Medium, or to High. Aim, press, and hold to shoot water and wash off the dirt in the area.
Sometimes there will be passersby in the form of small animals that provide a bit more story to the area!
Exchange Wastewater for Cleanup Reputation
After completing a stage, you also get a certain amount of Buckets of Wastewater, which you can exchange in the Cleanup Reputation menu for some Cleanup Reputation! Like the in-game Reputation System, the higher your reputation, the more rewards you unlock.
Check Exchange Rates for Your Friends!
You can also check the Exchange Rates for Wastewater to Cleanup Reputation amongst your in-game friends. You can head to their Exchange Screens to get Cleanup Reputation there instead, and even give your friend a flower!
The Exchange Rates are in the 40 - 60 wastewater per Cleanup Reputation range. They are generated randomly for each player and refresh at 4:00 and 16:00 (Server Time).

TokyoQuaSar almost 2 years
TokyoQuaSar almost 2 yearsI guess it will be hard to find someone who hasn't connected for more than 2 weeks here. You mean all ascension bosses right ? I would be surprised if hypostases worked and not Tulpa Hydro... I assume the problem isn't that I chose Tulpa but the fact that I didn't use my resin on it...

I kinda missed the "Claim rewards" part. So yes it's not the type of boss that was wrong but the fact I didn't claim the rewards. I don't plan on ascending anyone currently so I guess I won't do this challenge mission...
