In The Book of Moons there's a passage:
Also another passage about a Cataclyst:
"The greatest of the darkness being the power closest to the world & the underworld, the cataclyst. The greatest of the light being the power closest to the world & the underworld, the natural. Where there is not one there cannot be the other, as without darkness there can be no light."
- Elemental Manipulation: Cataclysts are easily able to control the weather without hesitation, and can control the elements: fire, earth, air, and water. Their "go-to" element is fire and can start fires by accident called "The Wake of Fire."
- Time Control: They are able to control time, but it's very rare if they can.
- Reality Warping: They are able to manipulate reality at ease. So easy, even Sarafine was able to warp reality with Macon Ravenwood.
- Kelting: Kelting is extremely rare. Most Casters aren't seen to do it, only very powerful casters.
