Duple Light (Alt: Duple Light) is a 3rd class active skill available as Arch Bishop.

Calls forth two sacred lights, Violet Granium (Duple Strike) and Yellow Merriam (Duple Magic), that will assist the user's normal attacks periodically.

• This skill does not activate:
  • With Ranged attacks or Skills.
  • On missed attacks or an attack that kills the target.
• Duple Strike uses weapon property, is Ranged (blocked by Pneuma) and is affected by cards that increase Physical Attack.
• Duple Magic is Neutral forced and is affected by cards that increase Magic Attack.
• When Reproduced by a Shadow Chaser, carries status effects of the equipped arrow.
• Autocast from Duple Strike, Duple Magic, and other Autocast equipments (such as Ring of Flame Lord and CD in Mouth) are independent. So it's possible to trigger either one or all of those in one single strike.
