With the release of Destiny 2's latest expansion Forsaken, new sub-class abilities and supers have been added to the game.
These require the acquisition of a Seed of Light, and then the completion of a mission for the Traveler.
However I used the opportunity to complete my Triumph for using each sub-class super in a single activity. This left me with the three sub-class skills still locked.
The skills state that you have to unlock them by defeating enemies using the super ability, but gives no indication of how many.
How many enemies do I need to defeat with my new super ability to unlock each of the three remaining sub-class abilities?
