Mmm doesn't work in the Char Builder. It is not a class implement (although it is an implement usable by a class) so it doesn't count for AIP. IMO though, CustServ it; just for a laugh![]()
Also, by RAW, the Half-Elf's Dual Heritage ability only applies to feat pre-requisites.
Of course, your DM might allow it anyway, so it's worth asking.
