According to patch notes, you can get them from Elite Savage Necrosises, or you can get them as rewards for augmenting stuff.

You equip it to a weapon or armor to either:
 * Give it another level (like change a 10* Striker to a 11* Striker)
 * Give it another star (like make a *** weapon a **** weapon, or a ** armor a *** armor)

I think the max you can put on a 10*** Weapon/10** Armor is two for each level, and one for another star (so you could make a 10*** Striker a 12**** Striker), I think.
