Warrior Skills

Fencing, Mace Fighting,Axes,Polearms,Martial Arts:
These skill cant be raised like Sorcerer skills like Wizzardy. The best way is to lvl with such items like swords,flails,artic blade,spear,wyvern claws. To raise these skills use minor damage weapons on a Maxed out Con char, which wont lose any HP when you attack the maxed out con char.

Archery:
This skill is best raised when pack a lot in your inentory and just shoot around on people   aura-ed in town, remember it only raises when you walk sometimes while shooting. Also handy to raise it while lvling.

Beserking:
Beserking is best raised if you dont have any strenght at all on the char you want to raise it on. Equip a weapon (or if you want to raise it using your hand.. equip some cloth gloves) and macro (or right click all the time) beserker and hit alot of monsters. You can also try to find a con char (a char with alot of con) and hit him non-stop, while also ofcourse macroing beserker.

Tactics:
This skill is raised when you raise all attack skills (Fencing, Mace Fighting,Axes,Polearms,Martial Arts,Archery) Every 1,00 tactis equals 1 Hp. Very handy for warriors and mages. Oh, and use a shield, makes it go up faster.
