PoE Titanic Impacts, Bow builds

Hey all, I am working on seeing what I can do to make this build function, and with xbox kicking offina few days, I wanted to get some feedback on what my take on it so far is. A few questions Is it feasible to use ballista totems to spike explosive arrow damage? What is everyone's previous experience with this build? what challenges should I keep in mind. &x200B;
