Masterful Power Mastery Achievement in Primal Survivors

This has to be done in a single run. If you play the easier 10-minute mode, you have just enough time to reach level 15. I personally reached level 16 on my first run. However, on the 15-minute runs you'll be doing for other achievements, this is essentially impossible to miss. You will unavoidably be leveling into the mid 20s during those runs, making these come naturally.
