Loxosceles:Of the thirteen major clans presented in VtM and Dark Ages, only two (offhand, correct me if I am wrong) of them have the potential to deal convenient aggravated damage at character creation using the default creation rules and allowances based on the in-clan discipline spread.
genty:Tremere blood magic i am certain can cause aggravated damage on vampires (from the usage of fire if nothing else)- Tzimitze bone craft gives them melee weapons with aggravated damage - Followers of Set
DICE:Asamites and Gangrel too.
genty:- Potence/Celerity combo discipline gives aggrevated damage (Brujah clan book)
genty:- Tremere blood magic i am certain can cause aggravated damage on vampires (from the usage of fire if nothing else)
genty:- Tzimitze bone craft gives them melee weapons with aggravated damage
genty:- Followers of Set (maybe not the first 13) with Serpentis 2/3 allows their tongue to cause STR+POT aggravated damage
