-Asra Nox can only be damaged when her guard is down. Wait until she uses a powerful attack and the shield icon above her is blue! [ULT ignores shield] Arrow keys, n as attack press space to move the target and click on it to remove it. number keys 1-7 activate different attacks in test mode. In the real battle she'll perform attacks on her own.
A starbound-inspired boss fight. You can retexture the Enemy sprites to make your own boss with the same attacks. note: Healthbar not available until battle mode is finished. Also, I couldn't find the original sprites for Asra, so I had to improvise by only using -Asra Nox from Starbound by Chucklefish
