General Notes



  • Warps away if any player is KOed before popping or during the fight and if not Red.png proced for a certain amount of time.
  • Extends the time limit by 15 minutes upon defeat.
  • Starting at 90% HP, Perfidien changes elemental weakness every 10~15%, marked with a Two-Hour ability animation.
  • The color of the Two-Hour ability cloud represents the element Perfidien is strong to. The element he's weak to is two elements ascendant from the cloud color.
  • Will change resistances tiers to 130% for the susceptible element and will then absorb that element's opposite affinity.
  • E.g. If Element: Water water is healing Perfidien, then Element: Thunder thunder magic will be it's weakness.
  • E.g. If Element: Thunder thunder is healing Perfidien, then Element: Earth earth magic will be it's weakness, etc.
  • Healing Perfidien will cause Encumbrance with duration based on the damage dealt.
  • For example, healing for over 7,500 damage will cause over 2 minutes of encumbrance.
  • Healing Perfidien enough will cause it to use Vivisection and level up.
  • Use low damaging elemental attacks to probe for the weakness.
  • Skillchains of multiple elements such as Light or Dark, will inflict the damage Perfidien is absorbing.
  • Blue.png proc and an /emote message appears when first inflicting the weakness.
  • Red.png proc appears when dealing ~23,000 damage of the weak element.
  • Changes weaknesses 2 minutes after the Red.png proc or after depleting a a certain amount of HP, whichever occurs first.
