Can I attack even after striking a deal?

I struck a deal with a slaver vessel. I will spare them for a slave. How do I attack after a successful deal? They are bad after all.

Solution 1:

If you end an encounter with a peaceful resolution, there's no way to manually force an attack. The only option is to move on.

The Friendly Slaver event has a special "blue" option if you have a level 2 teleporter where you can get a crew member and initiate combat.

However, as I mentioned, there's no way to choose a different outcome once you've completed the event.

Solution 2:

No, if you choose to purchase from them you will not be able to attack the slaver vessel during the Friendly Slaver Vessel event.

If you want to obtain potentially 2 crew members from this event, you will need at least a rank 2 teleporter and pick the blue option in an attempt to free some slaves.
