#Killling quinn
tawdry palm
flint wave
Just a thought maybe... not sure if this will work. Have a friend who's going to go to quint party up with you ahead of time and have your char afk somewhere near there so that when quint spawns your friend will kill him for you.

Unfortunately there's no workaround for quint. If you have access to your game though it really doesn't take very long. Just hit him once and that's enough. If you can take a 5 minute break you should be able to do it
