Autogold feature made AS superchest runs possible.
It consists of 9-12 superchests and summoner on fixed layout.
On paper this looks x2 times better, than LK runs with 3/6 superchests on random layout.
From x35 8ppl runs I got lum+fal+3hel+some other and 7 keys (yes, that was a lucky streak, I know). Even if we ignore HR drop chance, it seems better (and also faster), than countess.
Please, share your AS superchest statistics.
Arcane is good
Chests in LK can yield Sur and Ber though, whereas arcane chests are only up to Lo
Always nice to have options though
Yes, but sur and Lo have the same cost, and ber = 2 sur. There are x3 chest count + summoner, so you should get 4 Lo in AS per 1 ber in LK (x2 wealth on average).
Everytime i farm the summoner , i open the super chests if i took the wrong way. So far the best i found was a GUL (if im not mistaken 
) I almost never skip em cuz IMO they are totally worth it …
If ur saying do AS over the countess? Im not sure about that. I would say just farm the keys u need…
