Servant powers are abilities that servants develop as they age. Each servant will develop exactly one ability, from one of the six basic types: Materialization, Transfiguration, Alteration, Destruction, Integration and Mutation. A power's strength can be increased by three methods. Meditation and training are slower but safe and guaranteed to work. Emergence is unpredictable but gives larger jumps in power.
Their is evidence of servant powers is hereditary as shown by the Sandlords materialization of the compound silicon dioxcide (glass), The Rainlords materialization of the compound dihydro-gen monoxide (water) and Emiliana's inheritance of Agam Elroy's mutation type ability and the link to Gohvis.
Materialization allows a servant to materialize a specific element or compound from nothing and annihilate objects that they materialize. As the level of control over a materialization increases, the servant will be able to materialize larger amounts of material, materialize objects at longer range, more precisely control the shape of materialized objects, and even create objects moving or at differ temperature. Materialization does not allow a servant to change what they have materialized after making it but if a servant annihilates and materializes the element it can give the same effect.
While being able to use compounds instead of singular elements are still considered materialization because they work under the same conditions. It is known that having a compound is very rare so much so that only two have so far been mentioned They are the Sandlord power of silicon dioxide (glass) and the Rainlord power of dihydro-gen monoxide (water). Whether either of these powers can create other compounds involving their two elements has not been revealed. It could be possible to be able to materialize a compound with more than two elements but as of yet that possibility has not been explored.

Transfiguration also affects a specific element, but rather than allowing the servant to create their element from nothing they can instead turn sections of their body into their element. because they do not need to set the location and velocity, it is much easier for a servant with Transfiguration to control their element chemically and materialize it at high or low temperatures and because they create their element inside their body they can create chemical reactions with elements inside their body. Combined with soul-strengthening, this allows servants to use several powerful attacks based on normally harmless chemical reactions. Transfiguration also seems to come with a certain degree of chemical control after the time of use, such as accelerating or slowing specific reactions.
When in Pan-Rozum, transfiguration and materialization behave identically, distinguished only by element. Because transfiguration works within the servant's own body exclusively, where a servant's own soul always has power, it is the only power that can never be suppressed by enemy Soul power.
It is unknown at this time if Transfiguration users can have compounds instead of singular elements.
Alteration affects some force or type of energy, such as gravity, the weak nuclear force or light. Its abilities are generally dynamic and powerful but prone to weaknesses to other abilities. In a general sense, many reapers consider alteration to be desirable and the most powerful type of ability, but can also be put at a massive disadvantage depending on their opponent like Karkash being able to control hectors iron but Hector being able to stop Karkash's lightning, Or Harpers visible light being disrupted by a reflective surface.

Destruction fires a pulse of distorted space in a geometric shape along a path. Anything caught in the so-called path of destruction will be torn apart by the expansion of space within the path which stretches material beyond its structural limits and completely destroys it. Destruction is generally considered the least versatile ability, but it is also generally the most likely to win in any contest of raw power, they are also quite commonly used in the backline in large scale battles where they dont have to rely completly on their own strength.It's also extremely dangerous when used in Pan-Rozum. It's use is not only extremely offensive but defensive as well. Destruction users can just obliterate any attack that is coming towards them. It is also unusual in that it is the only power whose form is almost purely academic, since any servant with destruction can put holes in the same things and the shape of those holes is rarely relevant.
While at first a Destruction type user can accidentally cut things without training and at first while barely being able to break a car window as demonstrated by Colt, A destruction user can train the range and width and likely power of their destruction ability. Garovel once stated that longest range of two kilometres and a width of two metres.
Integration allows for the fusion of disparate objects into a single whole, with properties of the original materials. It initially allows for the fusion of only two elements, but with the use of the hyper-state Pan-Wzrost it is possible to gain permanent access to new elements. Integration is also used in the making of several notable objects such as soul nets.
Unlike the other abilities, Integration is often seen as unsuitable for combat applications because it can only be used at touch range, but it makes up for this deficiency in support utility, and it is the only power that can be used to construct objects useful to most servants, although any servant can become old and powerful enough to use permanent soul-strengthening. It can also be used in combat if the user is old enough to use Pan-Rozum, allowing the user to fuse with surrounding objects and create a massive form with no weak points, similar to a user of mass Pan-Rozum.
Mutation allows the servant to permanently alter their body. Unlike most actions taken with a power, mutation cannot be reversed by regeneration or death and resurrection. Also unlike most powers, if not used regularly Mutation will occasionally affect a specific body part in a way that can be controlled but not prevented by the servant. For a long time Mutation was widely believed to be a disease that a servant might suffer from that would prevent the development of a power, rather than a power in its own right. Mutation is fairly rare among servants and many who develop it are either written off and immediately released by their reapers or make irreversible mistakes with their powers and cause enough harm to themselves that they ask to be released. However, Mutation also has incredible versatility because it can be used to do anything that is physiologically possible, and those results can be supported by soul power and regeneration. For this reason, it is sometimes known as "the anything power". Though before the discovery of DNA and proper analysis of the abillity, and its consideration as a disease it's likely the 'youngest' ability type as people in the past rarely used it.
Every mutation user has a set number of horns that determines what traits they will have predisposition towards. For example, two horns indicate predisposition towards mammalian traits, three horns for reptilian traits, seven horns for avian traits, ten for amphibian traits, thirteen for arachnid traits.
