Since I now own this weapon, I can finally show the mod I put on. For those bonus damage buffs, go for Sac Pressure alongside Sac Steel, but it seems fine placing the [Primed Pressure Point], loses the bonus, but still kills. Choose toxin because that's just what I use, those three condition mods are essential. You can swap out [Primed Fury] to berserker fury or quickening if you want. Want to heal while killing? Use healing return just like you have ElderBlade-NT in PSO2, drain blood from enemies.
That's just what my choices are.
