Purity augmentations

Purity augmentations are augmentations that grant your items a purity bonus. Most, but not all, purity augmentations may only be removed by destroying them or using a Perfected Augmentation Distiller.

Purity
All class / visible armors and some weapons that have been created since The Buried Sea expansion have the potential to have infused stats added to the armor. Infused simply means you have a power source in use, and Infusible means it can be infused with a power source. Weapons that are infusable have pretty much been phased out.

List
Here are some purity augmentations.
 * Extra Planar Potential Shard
 * Priceless Diamond of Ethernere
 * Purified Flawless Faycite Triad
 * Stone of Tranquility
