When I look around the web for any information on atma drop rates from fates all you can find is people complaining about the drop rate of atmas and that SE needs to fix it.
SE is telling us that the drop rate is between 7-10% on atmas from fates while a lot of the player base is saying that drop rate is 1% or less.
The thing that I have noticed is that it seems some fates seem to drop an atma a decent amount of the time while other fates do not seem to drop it at all. I would not put it past SE that some fates can drop the atma at 7-10% while other fates have a 0% drop rate. If this is the case that would explain why it seems to be around the 1% drop rate that the player base is saying it is. This would also explain why some people have farmed for 4-8 hours and not gotten a drop. Someone in my LS has said they have farmed for 20 hours before without getting a drop but they also have said that they only stick to low level fates since they can do more of them. If that person kept hitting fates that have a 0% chance to drop then that would explain why it seems like some people have bad luck with the drop rate.
I would like for this thread to be a place to post confirmed fates that do drop atmas. If we can come up with a list and figure out which fates drop atmas and what ones do not then it would be much easier to farm for atmas.
Please keep this thread to constructive information so we can help everyone out with getting their atma weapons. Please do not complain about atma drop rates in this thread. If you want to complain about the drop of atmas take it to another thread please.
Post the zone and the name of the fate you have gotten an atma drop from. Please provide a SS if at all possible.
