I'm not sure who asked for daily quests and what is essentially a battle pass in Black Flag Resynced, but here we are. Similar to Shadows, you can earn Data Fragments to spend on unlocking special cosmetics and keys in your Animus projects.
First off, make sure that you have the Eyes in the Dark project active, as this one gives you rewards in Black Flag itself versus AC Shadows. Otherwise, here's how to earn Data Fragments so you can spend them on new cosmetics and keys, which you can use to unlock further items in the exchange.
How to get Data Fragments in Black Flag Resynced
The main way you get Data Fragments is by completing anomalies located around the Caribbean. These activities first unlocked for me after I completed Sequence 4: This Old Cove, where you take over Great Inagua. If you open your map and press tab (X on controller) to open your quest log, you can cycle down to anomalies and look at all the different ones available.
The range of activities depends on which project you have active in the Animus, but generally they are quite straightforward, and either involve sinking corrupted ships and convoys, or completing short puzzle sections, such as the rifts. Once done, you'll earn the amount of Data Fragments listed, which you can then spend to unlock rewards on your active project track.
These rewards include cosmetics, weapons, but also keys, which you can spend in the exchange to purchase items themed around other Assassins Creed games, too. You'll get new anomalies to complete based on the timer above each one. So, if you complete one, you'll have to wait a while for another to replace it.
