"The scaled hide of the cold ones gives +2bonus to the rider´s saving throw instead of the normal +1 save given to cavalry models" The rule is under Cold One Cavalry page 46. But that applys for ScarVets on them as well, right ?
Yeah, its really easy to get a ScarVet/Oldblood down to a 1+ armour save, I was actually fooling around with Army Builder the other day and got an Oldblood down to a -1+ armour save even though by rules its impossible.
