The classifications, as named by Lavitka Horton, are as follows:
 - Contortion-Type Taint
    These bestow special abilites onto a Valkyrie once fully matured that can be actively
     used.
 - Dichotomy-Type Taint
    These bestow special abilities onto a Valkyrie that can be considered as being both
     Contortion- and Passive-Type Taints.
 - Human Taint Modifier
    These are Modifier-Type Taints that can only be applied to the Human Taint, which can't
     have any other Modifier-Type Taints. The Human Taint has a maximum of one Human Taint
     Modifier.
 - Modifier-Type Taint
    These alter the appearance or the duration of the Taint. They generally do not have any
    other changes. Most Taints can have a maximum of three Modifier-Type Taints.
 - Mutagenic-Class Taint
    The Taint can be obtained through mutation of a Standard Taint, or through mutation of
     a specified Taint. These always have some other form of requirement. It is possible to
     gain this Taint without mutation, however.
 - Passive-Type Taint
    These bestow special, passive abilities onto a Valkyrie once fully matured, such as
     night-vision.
 - Sealed-Class Taint
    These Taints were impossible to attain, as the requirement(s) had been sealed away; it
     includes the fifteen sealed elements. These stack with the other classifications, as
     a result.
 - Syncretism-Type Taint
    These Taints are only available to Valkyrie fusions. Even then, these Taints have very
     strict requirements to attain. The first Syncretism-Type Taints were discovered with
     the first fusion of three Valkyries born in 2021 to Evan O'Neill and Valkyrie Horton,
     notably. These Taints are otherwise treated similarly to Contortion-, Dichotomy- or
     Passive-Type Taints. Because they are fusion-exclusive, their rarities will be listed
     as [XX] instead.
 - Tomoe-Class Taint
    The Taint's recovered eye contains a few "tomoe" (if you've seen the Sharingan from the
     "Naruto" series, then you've no doubt noticed the funny black shapes in the eye; the
     Sharingan can have one to three tomoe). These Taints start off with one tomoe, but can
     become stronger over time or through various events (such as witnessing some traumatic
     events or jubilation).
 - Unbeknown-Type Taint
    These are the Taints that do not fit any of the other classifications, mainly because
     too little about the Taints are known.
