#23 artifact gifts

[hjfhgf jhjkgkjg]

as well as my other questions about modding the game to include new character classes....
I have a problem with one of my mages.
I finally got the artifact rifle to be a gift (first gift even though it's second in the list).
But
I wanted to have at least one of the gifts be a spellbook of poison blast.
I can not get it to gift me a spellbook... Is there some place I can add it so that the air mage gets a spellbook first or second gift?
