Skills

A strong generalist fighter with a focus on debuffing, Chaos Ruler is a direct improvement to Dark Fencer with added flexibility and power - combining the chance of unique strong debuffs (ParalyzedCan't attack

  Debuff resistance lowered by 5% / 10% / 15%. reduces the debuff resistance of all parties and foes while also increasing foe special attack DMG. Chaos should only be considered as a skill for very coordinated use to land certain status effects in fights where the enemy gains resistance over time. In any other fight it is likely to do more harm than good and not worth using. The ChaosAllies' and foes' debuff resistance and foes' special attack DMG are modified as time passes

  as it will make things significantly worse!

Notable Main Weapons

As the Chaos Ruler has both Dagger and Sword specialty, there are many strong weapon choices available. The class is a generalist, so there are no 'perfect fit' weapon candidates, but none are counterproductive for the class either. Experiment to find one that fits your team and the fight you are taking on.

• Original Sin is a leading contender to be used as the Chaos Ruler's mainhand weapon. It provides a strong party-wide boost to multiattack on charge attack, debuffs become easier to land for the whole party, and the MC can no longer have their skills sealed.
  • Vigilante's Humanity - Boosts the MC's double attack depending on the enemy's debuff count. The MC mayhave trouble stacking debuffs quickly to enable this boost if you only bring  UnpredictableInflict 25% ATK DownATK is lowered
