After grinding list demons for a few days, I finally managed to reach 500 list points on the list! I'm very proud of this, and will probably take a break from extreme demons now, besides some levels like Kinetic Bypass. Here's a picture of my demon list stats as of 11/3/2017: https://gyazo.com/bf8622b95bbe85cfacc...
This level itself wasn't that bad for me, and I only had two deaths at the last wave. 957 attempts.
