I can't find the atma drop rate anywhere

[Fynlar]

2% was the number I saw floating around the most. 3% seems plausible too.

Whatever sort of time-based theorycrafting you read is bollocks.

When it comes to SE RNG, the number stated meant nothing unless it says 100%

Because in bad days, you can still botch 10 out of 20 desynthesis where the success rate is well over 80% lol

I remember my first weapon took some time, but the 2nd weapon was insanely fast because I got half of the Atma back-to-back within 10-30min time frames.

RNG.
