If you don't care how to calculate the Skill Transfer Value of a character and just want their rankings, look no further.

Skill Transfer Value Overview

WCharacter’s 5-star weapon STV weight.
SuCharacter’s support ability STV weight.
SpCharacters 3-star STV weight + 4-star STV weight + (5-star STV weight if character is a native 5-star)
ACharacter’s A-passive STV weight if it reaches final form by 4-star (or if character is a native 5-star)
BCharacter’s B-passive STV weight if it reaches final form by 4-star (or if character is a native 5-star)
CCharacter’s C-passive STV weight if it reaches final form by 4-star (or if character is native 5-star)

How do you know the STV weight of your characters’ abilities?  Here are the tables for each type of ability and their STV values.  The abilities' weights are determined by the rarity of the ability and their practical usage within the game.  Remember, only the final level of the abilities reached as a four star are evaluated (except for Life and Death 2, Quick Riposte 2 and Live to Serve 2).  Below, you will find the point score for each weapon, ability and passive.
