Notes[]
The following is a list of the codes used to determine the type of effect in a 'Complex' Perk Effect Block in FOMM and FO3Edit. The DATA block of these effects is 3 bytes long, and you'll need to input the below codes into those bytes in the order: type code | param 1 | param 2. It's unknown what purpose param 1 and param 2 have, but existing perks always have the same values for these params for each type code, as shown below.
