Yama

A very hit and run based boss, recommend using the ballast boost and ion beams/railguns. He appears in Reaper of Kalichi. Keep your distance because this boss has the ability to stun your ship, preventing it from moving or firing, as well as a flurry of high dps matter accelerators. Once your ship is stunned a flamethrower-like short-ranged attack will bring down your shield's and health quickly. When your stuck here I recommend spamming the ballast until your systems are back online. I also would use trip mines and deployable turrets/drones as they aren't limited to Axel's ship range.
