The Eclipse Armor is new armor worn by the Trollhunter, which is created by the power of the Triumbric Stones when they are inserted into the Amulet of Daylight. When the Trollhunter says "For the doom of Gunmar, Eclipse is mine to command!", the armor forms on their body.
Such as its counterpart, it is made of light, but in this instance, it is more likely to be moonlight. It appears with the Sword of Eclipse when the Amulet of Daylight is activated by the user and recognizes the Trollhunter in the process.
