While Characteristics are unique to the individual, Techniques can be used by anyone who tries to learn them, however learning a certain technique makes it harder to learn its Antithesis.
For example, Being skilled in Navigation techniques means being less skilled in Hunger techniques and vice versa. There is a reason for this, but it will be explored in the book.
There are 7 technique disciplines;
Navigation techniques: These techniques are mainly used to facilitate and improve movement across significant distances.
Stealth techniques: These techniques are mainly used to hide either all or certain aspects of oneself from being seen, sensed or located either by regular or supernatural means.
Insight techniques: These can also be referred to as Instinct, and Intuition techniques and grant the ability to arrive at an answer with less and less amounts of given information.
Exorcism techniques: These techniques are mainly used to bolster the user's natural healing capabilities.
Hunger techniques: These techniques are mainly used to manipulate Intent of oneself and others in all way, shapes and forms.
Resistance techniques: These techniques mainly give the user an increased resistance to the manipulation or application of certain things.
*********: *************************************************************
The abilities one can mainly use are not their limit and as such those at a point of mastery can create a new use of a certain technique or achieve something more from utilizing two or more disciplines together.
Also as said above, learning certain techniques makes it harder to learn another.
Navigation = Hunger
Stealth = Exorcism
Insight = Resistance
And in certain situations it is impossible for the user to learn another, such as possessing a certain "Accolade".
