EET changes find familiar spell to trigger K#FAMSUM.BCS, which does the same thing as original opcode 192 but allows to easily set which CRE file will be spawned (different in BG1, BG2 and ToB). Also vanilla familiars trigger K#FAMKIL.BCS on death (via cast spell on condition opcode) in order to implement the same penalties as opcode 192. This way the system is completely unhardcoded and does what we need using vanilla CRE files with no other changes necessary. I'm all ears.
