Critical Heavy Thermal Chestguard is heavy armor, crafted by the player with the Synthweaving Crew Skill. The schematic can obtained by chance when Reverse Engineering a Heavy Thermal Chestguard. With all crafted items, an Augment slot may open up when the item is crafted, allowing additional stats to be applied to the item. In addition, the augment may also change the level in which the armor can be equipped.
