Q:
Can precursors drop from Fractals chests?
Every chest that can drop lvl 80 weapons, can drop precursors.
Every chest that can drop exotic lvl 80 weapons, can drop precursors.
Fixed.
When a chest that has a chance to give a random lvl 80 exotic, it can be a precursor.
Of course having a precursor is much harder than having an exotic.
(PS: With devs, we are never sure of anything. They can easily remove precursors from some loot lists without we know.)
