I’m sure this has been suggested before but I didn’t see it so sorry if its a repeat.
I haven’t tried it but I’ve been told its impossible to salvage infusions from ascended rings or back pieces and that the infusion doesn’t transfer over when upgraded with an infusion. Would be great to be able to hold on to or reuse crafted infusions costing 5-15g, whether it be through mystic forge, salvaging, or transmutation.
