Surgebinder

Worldhopped from Roshar, a surgebinder can utilize Stormlight (concentrated power) to alter the way their surroundings interact with each other. Surgebinders are able to manipulate the Surges, the forces that run the universe. The 10 surges are: Adhesion, Gravitation, Division, Abrasion, Progression, Illumination, Transformation, Transportation, Cohesion, and Tension. Surgebinders are grouped into 10 categories, known as the Knights Radiant, guardians of light. 

Stormlight Usage

You are able to use Stormlight: pure, concentrated investiture (power), in a gaseous form. Stormlight is stored in gemstones. Your supply of Stormlight refills once per long rest, as being a surge binder draws power into gemstones on your person. The gemstones that Stormlight is stored in are grouped into three sizes: chips, marks, and broams. A chip stores 1 unit of Stormlight, a mark stores 10, and a broam stores 100. Stormlight is inhaled from gemstones on your person and held inside of you. It drains from you 1 unit per round, as "the human body is too porous a container.(Sanderson)" While holding Stormlight, your weapon damage, strength modifier, and speed is doubled. While holding Stormlight, you can chose to expend a number of units to expend for an equal amount of HP. Stormlight is also the means by which a surgebinder utilizes the surges and powers Shardplate. A surgebinder can infuse Stormlight into objects. It takes 1 unit for a tiny creature, 2 for a small, 5 for a medium, 10 for a large, 50 for a gargantuan. 

Radiant Order

As a Knight Radiant, your powers are grouped into the 10 Radiant Orders. These are: Bondsmith, Windrunner, Skybreaker, Dustbringer, Edgedancer, Truthwatcher, Lightweaver, Elsecaller, Willshaper, and Stoneward. Each Radiant Order has the ability to manipulate two of the surges. Each order also has a specific type of spren that grants it power.

Spren are beings of sapient investiture that can talk and interact with you or whoever they chose to show themselves to, though some can't disappear completely. You can always see your spren, and they can always see you, and know where you are always. They don't really exist in the physical realm, so they can't die. A spren can scout places out for you, or look behind locked doors, as they are invisible to all but you, silent to all but you, and have no real mass. Someone appearing to converse with their spren would be appearing to talk to thin air. Spren can come in many different forms, some looking like ripples in the air, others looking like translucent people, it all depends on what Radiant order you are.

Edgedancer

As an Edgedancer, you have bonded a Cultivationspren and are able to use the surges of Abrasion and Progression. A cultivationspren looks like a long stream of vines (usually 4-6 ft) with rounded crystals jutting out at random intervals. A face made of the vines appears at any point along the stream depending on the orientation of the stream of vines, which behaves like a snake and can crawl up walls. The surge of Abrasion allows an edgedancer to control the friction affecting themselves or objects they infuse with Stormlight. They can make themselves and whatever they infuse slick, like there is no friction present at all. can be used to escape entanglement, slide at extremely high speeds along the ground, and to make objects slick beyond all reason. The other surge available to Edgedancers is the surge of Progression, which heals other people using the same rules as Stormlight healing, which exchanges 1 unit of Stormlight for 1 HP. 

Lightweaver

As a Lightweaver, you have bonded a Cryptic (Liespren) and are able to manipulate the surges of Illumination and Transformation. A Cryptic appears to be a 2 dimensional, undulating, reciprocating pattern that has a 6-way rotational symmetry. The surge of Illumination allows a Lightweaver to make medium sized illusions at close range, such as a false wall, or a being that isn't there. This takes 5 units of Stormlight. A Lightweaver can also make illusions mapped onto themselves, changing their appearance or the appearance of objects they are carrying as long as they can fit inside of the illusion. The surge of Transformation allows a Lightweaver to change any substance into another, though it follows the infusion rules. To change a creature, though, you expend two times the creature's HP in Stormlight. 

Skybreaker

As a Skybreaker, you have bonded a Highspren and are able to use the surges of Gravitation and Division. The surge of Gravitation allows you to change gravity for yourself (and whatever you're wearing) or other creatures/objects. You look in the direction you wish to change gravity in, and Lash (will the gravity to change) the object in that direction. It then forgets the ground's pull on it and acts as if the Lashed direction is down until you either dismiss the lashing mentally, or when the object runs out of Stormlight. This principle also works on yourself, though it only takes 2 units of Stormlight to lash yourself. Lashings last until you run out of Stormlight. Half lashings upward make you weightless, as your body is being pulled upward partly, while still remembering that it should be falling down. You can perform as many lashings as you want during a turn, though you can only move roughly as far as your movement speed allows. The surge of Division allows you to burn, degrade, or disintegrate anything that you infuse with Stormlight. It also works on creatures. To burn a creature, you expend two times the creature's remaining HP in Stormlight. 

Windrunner

As a Windrunner, you have bonded an Honorspren and have access to the surges of Gravitation and Adhesion. Honorspren look like small glowing blue personages about six inches tall that floats around. The surge of Gravitation allows you to change gravity for yourself (and whatever you're wearing) or other creatures/objects. You look in the direction you wish to change gravity in, and Lash (will the gravity to change) the object in that direction. It then forgets the ground's pull on it and acts as if the Lashed direction is down until you either dismiss the lashing mentally, or when the object runs out of Stormlight. This principle also works on yourself, though it only takes 2 units of Stormlight to lash yourself. Lashings last until you run out of Stormlight. Half lashings upward make you weightless, as your body is being pulled upward partly, while still remembering that it should be falling down. You can perform as many lashings as you want during a turn, though you can only move roughly as far as your movement speed allows. The surge of Adhesion allows you to stick an infused object (or being) to any other object (infused or not). It then remains stuck there until you dismiss the bond (called a full lashing), or until the starlight drains out (1 unit per round). 

Shardweapon

A Shardweapon is the essence of your spren fully pulled into the physical realm. Shardweapons are incredibly light, unbreakable, usually 6 feet long, and so majestic that some creatures freeze in their tracks at the sight of one. To summon a shardweapon, a knight radiant need only to hold out their open hand and, as if forming from mist, their weapon appears. Shardweapons can cut through anything inanimate as if it were water. The metal fuzzes and dissolves into mist temporarily if sliced through a living being. These weapons don't slice flesh, they sever the soul itself. If the core of a limb is hit, it goes dead, grey and lifeless, unable to be used for the rest of the creatures life, unless they are a surgebinder themselves. If the spine is hit, the creature instantly goes dies, radiant or not, with eyes burning in their sockets. If a shardweapon is dropped, it instantly dissolves into mist. While a shardweapon is summoned, your spren can speak to you from the weapon, but cannot move around on its own, nor can see any more than you can. A shardweapon can be in the form of a sword (Shardblade), spear (shardspear), or a shield (shardshield). It can change on whatever you feel the need for in the moment.

Shardplate

Shardplate is a mythical armor available to only a full Knight Radiant. It has no chinks, nor space between pieces, just smaller plates. It is seamless and flawless, perfect always. The only opening is the eye slit in the helm. The armor is summoned onto yourself, it isn't put on. You must be holding at least 50 units of Stormlight to be able to summon the armor, though none is consumed in the summoning process (1 action). While wearing the armor, you leak no Stormlight, unless the armor is damaged. The armor weighs about 1/2 ton, but grants enhanced strength, so it seems weightless to the wearer. Each general piece of the armor (helm, breastplate, pauldrons, vambraces, greaves) has a health of 10 times your constitution modifier (you don't take damage when hit). Shardplate doesn't dent or bend when hit, it cracks. When a piece is cracked ( < max HP), you lose 1 unit of Stormlight through that crack. When pieces are reduced to 0 HP, they explode off of the wearer in a flash of molten metal, and the body has to then support the remaining pieces attached to the wearer. For example, hobbling if a leg piece is shattered. If a breastplate is shattered, the rest of the armor becomes so heavy it is hard to move. While wearing Shardplate, the wearer's strength modifier, speed, and weapon damage multiply by 5. Also, your constitution modifier is added to your AC.
