I was planning on going lightning arrow champion when I saw this post on r/PathOfExileBuilds, https://www.reddit.com/r/PathOfExileBuilds/comments/12xv2yg/this_weird_lightpoacher_interaction_is/. In the comments I saw this question from d2WarlockNeedsLove asking if Voidbringer could be used to prevent Lightpoacher from triggering the skill and consuming spirit charges**:** https://www.reddit.com/r/PathOfExileBuilds/comments/12xv2yg/comment/jhmpw95/?utm_source=share&utm_medium=web2x&context=3. I was able to test out the interaction and it works. Removing mana happens before Lightpoacher attempts to trigger. Because of that the spirit charges are not spent. With that proven the rest of my effort was trying to get the rest of the build up and running. Note you need to have at least 20 unreserved mana and voidbringer needs to remove all of your mana to prevent spirit burst from triggering.

Since I am using lifetap on my main skill manaforged arrows does not work. I have to manually use frenzy to keep up charges. The bow is pretty bad and the rings probably need to be replaced but the build feels ok. Single target is also slow. Currently this is work in progress. I figured I'd share because some of the other ways of preventing charges spent were hard to do from duelist start.
