Okay, I've got it now.
It is a bit more complicated than what we've been doing.
Here is the Activation Script:
Code:
$SET_CHAR_ASL($TargetIndex(),"strength25",25-#$GET_CHAR_STR($TargetIndex()));
$SET_CHAR_STR($TargetIndex(),25);
And the Deactivation Script:
Code:
$SET_CHAR_STR($TargetIndex(),$GET_CHAR_STR($TargetIndex())-#$GET_CHAR_ASL($TargetIndex(),"strength25"));
