The way they talked about it at the council meeting thingie, it seemed it will be permanent. As are the daily free gacha pulls.
Anyway, I managed to beat floor 80 of the castle this time, after getting Forehead-chan and rarity-ing and ampy-ing up Lily and Otomegikyou. Not sure if I could do better, but I'm out of materials in any case, so this will be a question for another time.
...and here's the team:
Next time, I think I'll also have to write down the most effective combinations of knights for each floor to make the whole process a bit more seamless. I feel like I could clear most of the floors with only 3 archetypes:
- drain with hp increase FM
- 1st turn kill party
- drain with taunt FM + heavy hitters (for where my regular drain girls couldn't dish out damage fast enough)
In addition to that, I used:
- crit + 2x skill + negate for the ones that needed 2 turns of heavy damage
- multiple target crit + counter for those candle slugs
- special party for 50
- special party for 80
