I just had an appreciation for today's sortie. When fighting the jackal, you have to parazon mercy kill it. There's this cool animation sequence and I feel like this is how other assassination quests should end. It's a shame that you can only parazon kill the jackal and exploiter orb iirc. I'm aware about mercy killing/finishers for normal enemies, but that's only for your eyes. I think it would be nice if other assassination bosses were killed similarly.
I feel like that's more of an option to get after getting kullervo and his gun. Cause after that, if you ever encounter him and get the new resource after defeating him. You'll just have extra of it. I think it's a nice small source of credit farming passively. Not the most effecient, but not terrible?
