Winning against Enemy Difficulty level 160 (HSR Currency Wars)

One last thing I wanted to do before the new CW iteration was this achievement. This was Wealth Creator 50 with 2 Prismatic Strategies and a Silver Strategy on the hardest difficulty Encounter Node. This ended up being Enemy Difficulty level 162. Halfway through I started losing hope and was misplaying a lot. But it turned out I had just enough damage and managed to clear the last enemy with my very last action.
