Ideally, this build kills with the first use of Ballista, though the run went on longer than I would have wanted, so the Zoarcids and Shuriken were needed to help kill opponents in the late game. Biomerge Arm gives Ballista 100% crit chance, doubling its damage cap. There’s a risk that the Ballista goes off too early before the Shuriken gets all of its casts and it doesn’t get enough multicast.
