you stack 15 plasma mines in a pile and Darth Sion dies

i actually like this bc it's a nice little (likely accidental) example of the gameplay backing up the story (which is a big theme in the game) - when you ask atton how he of all people was a feared jedi-killer he straight up tells you his method was something to the effect of "gas them, drug them, blow them up, shoot their friends and their puppy too, make 'em mad and make 'em make mistakes"

plus it's very in-character in general for him to look at a fair fight and go "um no thank you", doubly so since he's also your han solo type
