[Cainehill]

Hellsword has one potentially big advantage: it helps a SC go berserk, meaning that it will stay on the field of battle after all other commanders / troops have fled. This can be quite handy if you want to send in some chaff that you know will be eliminated (say, undead to wear down other SCs with lifedraining weapons) or if, like some pretenders, it's stuck with some auto-summoned minions.
