Berserkers!!!

[Harry Faversham]

We're having a Song of Blades and Heroes Viking raid game and I'd like to include a couple of berserkers with the baddies. What special traits would be best for 'em, can you be tough with no clothes on!?.
I know they were a handful when they came at you... being berserk and wotnot! But wouldn't a crazed, half naked bloke who's eaten his shield, be easy meat to a fully armed and armoured Saxon Huscarl?

[Ethelred the Almost Ready]

Yes, but fear makes you do funny things.  Also, being crazed makes you do funny things.  Think of a lone policeman with a baton vs a someone on methamphetamines.
