Looked for a thread and didn't see one.

I just want the stone. Ameno is the lowest-combo high-damage card (I think) that I have, and I STILL can't beat it - I've made it to f10 only once, with barely 2 or 3 seconds left. What are people using?

Edit: For anyone looking for answers, the consolidated list is Verse (pretty much everyone), NYKami (me), presumably regular Kami because of that, Vraska and Yog.
So, a "free stone" dungeon whose other prize is worthless for the effort/stamina requirement, and it seems it can only be reliably beaten with a single farmable lead (who granted is not that hard to get, but still), two 6-star GFEs, and a limited collab 6-star or 8-star pull. Terrible dungeon idea.
