Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods Beginner with the Toolkit request some help

I try to do a stand-alone mod and I would like to take some elements of the main campaign, like some scripts. For example I would like to copy/paste an entire fight but just change the names and skins of the NPC. But that seems difficult...

I tried to do a basic script to add a book to my charachter at the beggining of the game but I have a syntax error ("?" unexpected) my code in KB is :

IF
GameEventSet("GAMEEVENT_GameStarted")
THEN
ItemToCharacter(ITEM_Lightning_book,CHARACTER_Scarlett);
