How does steady hand + basic synth = failure?

[Mishini_Dracoto]

I use Observe

I don't / never have.

I'm 4* ARM, BSM, GSM, CRP, LTW, WVR, and 3* CUL & ALC.

Although, I will admit, it might be good to use Observe, if you have between 46cp and 60cp, and if one more careful synthesis will complete your synth, and you are trying to bait a good or excellent condition for Byregot's Blessing.

At low levels, this shouldn't matter.
