Progression
The Surge of Progression is the Surge of Growth and Healing, or Regrowth.
General abilities
Progression can be used to alter the growth and healing of organisms. The two orders of Knights Radiant with access to this Surge are the Edgedancers and the Truthwatchers.[1]
Growth
This ability accelerates organic growth to tremendous speeds. The Surgebinder can infuse the seeds to a plant with Stormlight through skin contact, and in seconds, it will become fully developed. It is unknown if this ability only works on plants.[2]
Regrowth
This ability heals the damage done to the body and the soul of a person instantly and without any scarring. The flesh, muscle, or bones can be completely regrown rapidly. The body can be refreshed and rid of fatigue.[3] The Surgebinder can even reverse death with Regrowth; a body that has bled out or a soul that has been severed with a Shardblade can be healed with Regrowth and continue to function as if it has never been damaged.[2] However, once the soul leaves the body and reaches the afterlife, it is impossible for the Surgebinder to revive the person.[4] This ability may also fail to heal injuries that are too old.[5]
Surge Fabrial
A Surge Fabrial is able to mimic the the Radiant ability of Regrowth. Ancient Radiants possessed fabrials constructed from a large topaz and heliodor that were able to "regrow" and repair injuries through manipulating the Surge of Progression.[3] In the present day, they have been lost; however, the Herald Nale possesses one capable of bringing someone back even from the brink of death.[4]
