Three new reward rhythms, all on one shared clock that resets at 00:00 UTC.
Daily and weekly objectives sit on the dashboard. Each asks for the things you are doing anyway - run missions, fight battles, train, run errands - and pays when you reach the count. Progress comes from what you have already done; there is nothing to track by hand.
The Monthly Activity Card stamps every day you complete any of those activities, and pays at milestone day counts, with Embers on the ladder. Unclaimed milestones go with the month when it rolls over.
