Setting an Attribute to a Specific Value (ie. "Feeblemind" spell)

[Mathias]

There is only one script that takes the value of [Penalty] and subtracts it from aFinalVal - so, if you run your script after aFinalVal has been calculated, there's not going to be another chance to incorporate the [Penalty] you want to apply into the final value of aFinalVal.

If you run your script before that final value has been calculated, aFinalVal = 0, so feebpenINT = 1
