Onslaught's Gameplay Mechanics

Basic Abilities: Daunted, Neuroshock, Crush, Organic Magnetism

  • Light, medium, and heavy attacks:

    • Light Attack: Does not make contact, allowing Onslaught to bypass certain defensive abilities.
    • Medium Attack: Also non-contact at the first hit, useful for avoiding reflections and counter-attacks.
    • Heavy Attack: Pauses all damage effects on the opponent, adding to Onslaught's tactical advantage.
  • Active and Passive Abilities:

    • Daunted increases the damage the opponent takes during special attacks;
    • Neuroshock inflicts significant energy damage over time;
    • Crush debuff increases in potency with the opponent's combo meter;
    • Organic Magnetism reduces power costs and increases efficacy under certain conditions.

Special Attacks:

  1. Special 1: Shrapnels: Inflicts multiple Neuroshocks and an Organic Magnetism debuff, making subsequent uses of this attack more power-efficient.
