While all angreal offer this benefit, they do vary considerably in strength. The amount of additional Power to which they provide access is dependent on both the angreal's strength and the channeler's own strength in the Power. The stronger a channeler, the more Power an angreal provides.
Sa'angreal are like angreal, but much more powerful. All known angreal and sa'angreal can amplify either saidin or saidar; none are known to exist that can be used by both man and woman. One sa'angreal is known to amplify the True Power as well.
Most angreal are constructed with a buffer to protect the user from drawing too much of the Power.
All existing angreal are left over from the Age of Legends. The knowledge of their construction was lost during the Breaking of the World, along with the knowledge of creating ter'angreal, although the making of ter'angreal has been rediscovered. Angreal are rare; sa'angreal are extremely rare.
Creating an angreal
Just prior to the Last Battle it is revealed that a ter'angreal called a Seed is used to create angreal. The crafter uses the ter'angreal to pour the Power for a very long period into an empty vessel. The process is said to greatly weaken the channeler that created the angreal for several months.
List of angreal

- In the second book, among Bayle Domon's collection of antiquities, there was a statuette, an ivory carving of a man holding a sword, which is suspected to be a male angreal, because of its shape and also because it felt strangely warm when some men touched it. This statuette could also be a ter'angreal.
