1. Use the -RAGE tag (eg. Salamander-RAGE, Menibiorn-RAGE, etc.)
2. Historically beserkers were seen as extremely strong, tough, and ferocious and often associated with bears. Legends speak of shape-changers which turned into bears during berserkergang. To show this association berserkers might assume a "bear name", meaning a name containing the element *bjorn* or *biorn*, such as Jaibiorn, Kvarobjorn, Olobiorn, Eflobiorn, etc. See the link below for other possible animals (i.e. Hildulf = battle wolf).
If you want an Old Norse name there's a website that has tons of different names http://www.flick.com/onomastikon/Europe-Scandinavia/Old-Norse/index.htm
For main armor slot: Berserks often wore animal skins into battle. Legends speak of berserks who shape-shifted into ferocious animals in combat. Therefore, berserks can wear ANY armor that is related to powerful animals (specifically: ox, fox, wolf, tiger, mammoth) Otherwise, berserks are restricted to non-metal armor. The assumption is that plate armor of a certain animal is a collection of skins from that animal type.
For arms/legs: Up to chain/splint is allowed without the need for animal relation. However, plate can only be worn if it is animal related as specified above.
Helmet: Anything is allowed except for crowns (*crunch* *crunch* you call this armor? *spit*). Helmets that completely cover the face are only allowed with animal properties. Frightening helms (skulls/masks) are favoured, but are optional. Berserkers were usually terryfying on the battlefield due tue their rage, body painting, and their armor, so a frightening helmet fits the role.
Shields: Only buckler/small/large/spiked shields which give attacker damage. The attacker damage must be (clvl * 0.25), so at level 20 you would need 5 attacker damage on a shield to use it. Eventually, berserks will have to forsake shields and use more offensive weaponry. Large or multiple weapons are of course preferred to shields but a large berserker running at a group of enemies with a gigantic spiked shield and impaling them on it is pretty cool.
Weapons: Any weapon class is allowed, a frenzied warrior really doesn't give a damn which weapon opens his enemy's skulls. Throwing weapons may only be used in melee. Poisoned weapons are disallowed (ARGHHHH! Oops, wait gotta stop and poison my weapon........ ARGHHHH!). King's, Lord's, and Knight's are all disallowed (berserkers were pretty low in society because of their tendency to go berserk and kill their own people).
Jewellery: Only one exception. Ease and simplicity (- reqs) are disallowed, battle isn't an easy affair, items that simplify battle are for cowards.
War Cries: Battle Orders and Battle Command are restricted. If you really want to use War cry you can put points into these as prereqs but War Cry takes a lot of mana. Find potion/item are restricted to 1 point and grim ward is restricted to 4.
Combat Masteries: Throwing mastery is restricted. According to legends, berserkers were very hard to kill due to their painless rage. Iron skin must be pumped once you get it and at least once every 10 levels thereafter. Natural Resistance, Increased Stamina, and Increased Speed must receive at least one point after they are available (when in a berserking rage, berserks can go on fighting for long periods of time without tiring). Everything else is unrestricted.
Combat: Leaping can only be used to close in with the enemy, not to escape. Whirlwind can be used to initiate combat with a group but is diallowed once close combat begins (i.e. no dance of death). Frenzy, Berserk, and Double Swing are all prized skills and should all receive at least one point. Try to use them if you have a chance.
Behaviour: Much like a Death Knight, a berserk can not retreat. He will fight to the death. However, unlike the Death Knight, this is not an issue of honor or appearance. Once a berserk begins combat, he has limited control of himself and only desires to wreak havoc. Berserkers are also often lonely people. The fact that they can snap at any moment and kill everyone around them makes them a teeny bit unsociable. I don't want to restrict coop-play, so if you do end up in a party try to SCREAM a lot and generally act like a a berserk.
Example:
Sorceress - "Ok, when Diablo comes we retreat back to the-"
Menixulf-RAGE - "I SEE HIM! ARGHHHHHHHHHH!" *charges Diablo*
Sorceress - "What the!? Get back here!"
Menixylf-RAGE - "ARGHHH!" *chop chop smack gut splat slash*
Sorceress - "Damned berserk!" *joins battle*
