I have a couple of questions; first of all, when using vesper, does the circle you target affect enemy models or is it just used to determine which path the 3 auto successes can effect? Meaning, does the special attack hit two models or just one? Also, do all voivodes on oksana's team use the smiljian-b and prime directive 0? Or just the two that she "controls"?

My interpretation is that the adjacent circle is just used to determine which figure gets attacked in its range.

I believe that all Voivodes on a team with Oksana benefit by having their Smiljan Coil replaced by Smiljan B Coils and Prime Directive O as well as using any of Oksana's special Voivode items.
