Each infusion consumes a certain amount of enhancement points from the item. Looted items start with a pool of 100 points (meaning they can only receive one infusion), while crafted ones have 120 (meaning they can receive an infusion and some other [[Blacksmithing]]/[[Tailoring]] enhancement).  After an item has been infused with Shamanic infusion, it can also be undone, just like a normal augment, with the "Undo Augment on X Armor" skill.
