To answer your question, you need to spend at least 100k AP in phase 4 advancements in order to unlock super ascension. Once you have done that, you will see a super ascension button at the top of your idle dashboard. Click it, select your chosen perk, and away you go.
Didn't we SAsc for the first time with like a week difference? Now you're at 6 and I am still at 1. But I am really close to 2nd, need 12 more uncommens.
My first super was 2022-12-08, and then it took me roughly 1.5 months per super on average. Going for +AP is usually faster than collecting a legendary artifact.
Yeah, and I need a total of 2 Leg+2 epic to turn my 3 Leg into ins+2 epic. Future SAscs will be way faster, since I won't ever dig that much in one SAsc again
