Slash Tower extension floors 21-30F all cleared on full auto, with explanations. Level 80, start of Summer 2024 event.

The difficulty on manual is decent, assuming you have the core slash units. May need to craft some specialized gear. The auto is pretty hard, a lot of RNG and interesting sequences. A lot of high trait niche gear, like buff A + area defense 10s.

Actually ended up using Firis Initiative a lot, never expected it to have much practical value, but it's really good for bypassing various things and getting through fights faster.
