for vanilla void i think you’re fine with orpheus or gyrfalcons. i do think prismatic is better for lethality + better on demand access to invis if you run the solitude fragment (sever on precision hits) with the stylish executioner aspect. gifted conviction is also worth looking into with the ascension aspect. GM’s are a lot easier than they used to be, so inwouldn’t worry too much about it. run whatever subclass you’re most comfortable with
