Oh... the 1st one... finally I found it...
Here it is, Line 318 in the head file inc_newspellbook.nss in prc_include.hak:
int nAbilityMod = nClass == CLASS_TYPE_ARCHIVIST ? GetAbilityModifier(ABILITY_WISDOM, oItemPosessor) : (nAbilityScore - 10) / 2;
so Archivist appears to be a really special one... then I tried to edit it but failed, then I remember that nearly ALL scripts will have to be recompiled if a header file changes:o
So... can I just ask how to compile scripts... or do I have to drop?:|
