Tips and Details

  • The skill only pulls in enemies towards the hitbox's center and has no other suction effect of any kind. The hitbox of the skill is also much smaller than the visual effect would suggest.
  • While other SP using skills or commands consume SP the moment they are used, this skill will not consume SP prior to Laby punching the air in front of her.
    • This allows the skill to deal maximum damage when cast at 6 SP while [Enhanced] Inner Aurora is active, as you will reach 10 SP right before the attack happens.


  • -mixis is a term usually used as a suffix in biology in relation to reproductive methods (i.e. apomixis), and simply means 'mixing'.
