There are lots of reports of atma one shots, I've only just started, I have two, the first was about 8 fates, the second was the first fate I did in the zone.

It may just be RNG, but RNG is not always particularly random, and there are ways of messing that code up such that it forms very predictable patterns or odd behavior. With as many reports of one shots as there are I'm willing to believe theres something to it.

But anyway, I don't plan on taking it very seriously, I'll just do it as I wait for queues (and being a WHM, that's not much so far)
