I did a ctrl+f “amulet” and never did you write that word.
Just keep trying, it is the best way to obtain the conduit amulet blueprints.
Conduits have skill modifier prefixes which are obtained onced crafted.
so it is 1 in 11 chance to get the desired prefix on crafting.
In addition, they also get a suffix which is the resistances part. And there are 5 in those.
In total, 1 in 55 chance to get the desired prefix and suffix.
