Behavior Edit

Rock-On has a multitude of attacks it can levy against the Builder. All but one of its attacks hit multiple times, so it's imperative to escape before the Builder takes too many hits.

All of these attacks can be used at the beginning of the fight.

  • Firstly, when in very close range, Rock-On will attempt to drill the Builder.
  • Secondly, It has a medium range arm swipe attack, where its arms are covered in electric currents. Unlike Rock-On's other attacks, this attack only hits once, but hits for rather high damage.
  • Thirdly, Rock-On will do a horizontal spin attack, which hits a great number of times. It is advised to avoid going near Rock-On when it's using this attack.
  • Lastly, Rock-On will do a vertical spin attack. However, just because it's spinning vertically, doesn't mean it won't turn to face the Builder in this state. Just like the other spin attack, this one also hits many times, and it is also advisable to avoid Rock-On when it's doing this attack.
