A "?" in an effect means the source entry leaves that number as a blank template value; it is shown as unknown rather than guessed.
Skill and trait names are our English translations of the Chinese client data; Lumi names are the official global names. If an in-game English skill
name differs, the effect text, SP cost and Power are what to match on.
