question about creating new spell

[ughfhhyg4555786]

If I create a text file with new entry in Public\my_mod\Stats\Generated\Data, does the new entry actually create a new spell in the game, or must the new entry be a spell that already exists in the game (like Replacement)?

 

for example,

new entry "XX"

type "SpellData"

data "SpellType" "Shout"

data "Icon" "Action_DivineIntervention_Attack"

data "Level" ""

data "SpellSchool" ""

data "DisplayName" "h28ef3af2gddf1g4280ga47agb801a76;1"

data "Description" "hc32a0860g7654g49a5g917egd77f048;1"

Does XX have to be the one that in the game?
