Trsits Adversary (Major): King Harald of Norway. Brave (Minor): When it's time to fight, it's tough to keep Egil away. Eccentric (Minor): He is prone to fits of melancholy and silent brooding. Impulsive (Major): Once Egil's blood gets going, he's prone to taking rash action. Indomitable (Major): He keeps fighting to the bitter end. Tough (Minor): Egil can withstand a lot of punishment before he's down for the count. Unattractive (Minor): He's quite ugly.
I'm not too certain how to do his berserking -- I've given him a Major version of Impulsive for now, but I'm not too certain if that would cover it or if I should make a new Berserk Trait. Thoughts?
The stats for Viking Raiders in the First Doctor Sourcebook includes a Berserk trait, which says: "They can enter a fighting rage; when raging, they gain a +2 bonus to Strength, but have trouble distinguishing friend from foe."
It's a Special trait - no cost listed, but as 2 Strength would normally cost 2 points and this is a bit worse, I'd suggest only 1 point.
