and in that cases u will rarely use duelists (since they do single target damage , especially barbarians since they attack slower) unless for some sort of reason u can't use a ranged unit. If that's the case , you're better of using a rogue like cypria (for the chance to assasinate) or a ninja like saki (for both assasinate AND ranged dps that will clear waves before they even reach you). Duelists are there to act as single target tanks that can 1v1 a boss. Doing a fuckload of damage is pointless if you die after 2 seconds without healers. That is hardly a ....duel. Also , condrad's defense drops to 0 , so he becomes even worse vs physical damage. You could argue that he can perform better vs mages/liches/magical attack , but that's it.
