Chak Infusions are a type of infusion that can be obtained from the Mystic Forge. They are an upgrade to the Chak Egg Sacs found attached to Charged Quartz Orichalcum Amulets of the Chak. While Chak Egg Sacs provide Celestial stats, the infusion version is limited to the stats of the Agony Infusion it is combined with. The infusion will still provide the same particle effects as the original upgrade.
