ok for minbari when you roll to hit you have a plus one to hit so on hull 5 you need 4s to hit because of precise. when you roll for damage you roll 1d6 + 1 for AP so dose that mean on a roll of a 5 its a critical cause 6s make crits and 5 + 1 is 6 and for like shadows and vorlons they would need 4,5,6 to crit right. and on a victory a 5 and 6 would crit from a minbari ship right.
