Fumbles, don't get mad if i post it here. If you disagree, let me know and i will move it somewhere else.
A lot of things changed since this guide was released and ... removed. But i still play tantrum barb and it rocks my world. Maybe it will rock yours too !
It's a strong and fast char to farm SPECIFIC areas and fails hard in some other areas.
Everything is pretty straight forward. Tantrum is skill that works best when enemies come at you or teleport on you. When they stay ranged and atack - bad.
The more +x on tantrum = longer duration of tantrum circles. Skill hits many times per second so big weapon damage is not need, what is need - crushing blow, deadly strike, +xx to cold/fire/ligthning/magic damage, leach, on striking procs.
For leveling put 1 point in stances, 1 pt in all sword tree, keep wolves maxed, beer stance and use sword vortex skill until you reach lvl 21 and can use this -
Runeword Level: 21
2% Chance to cast level 9 Gift of Inner Fire when you Kill an Enemy
10% Increased Attack Speed
+(24 to 35)% Enhanced damage
+(1 to 6) to Tantrum
+1 Life on Striking
. Then restat from bear stance to wolf stance. While leveling keep these skills to max: deadalus, wolf stance, wolf companion, spirit guide. Gear choice is simple too: Amor rw in bow, jitan kamon armor, wormtongue belt, lionpaw boots, honorific gloves for resists, auriel's halo circle as helmet, +1 skill rings with resists MOed, +x skill amulet with xp and resists. This simple setup lets you go through hatred and terror np. When you get lvl 90 - choose runemaster and immortal skills - max them.
At lvl 120 try getting sacred xbow or bow for shrine crafting. Look for tantrum (obviously, doh) and some proc like arrow or knife proc. These are very good but not mandatory. My current xbow is without them and still works. Armor - rw Erawan or rw Dragonheart. Both nice, Erawan gives nice damage reduction, Dragonheart - atack speed and +2 skills. Try str/dex shrine crafting for boots and gloves. Belt can stay same. Try to find rare bolt quarrel with proc on it, cryo beam is nice to get.
With this setup you can get some charms, do some ubers, easily farm some nice areas. For other charms you will probably end up restating.
Good and easy areas to farm:
Cows - easy to do, boss jumps on you - his own fault.
Khalimgrad - easy to do, everything walks into you - dies. Keep a potion or two if you are poisoned by punishers.
Bremmtown - easy if you can reach it and have enough damage to take first hit. For example using Jitan kamon in there is great. First group of dead mobs creat towers, you walk half screen to stay in range. Next group jumps on you - gets raped by tantrum + tower support. Continue.
K3K is average - need speed and lvl 90 skill for stun novas. Then run to totems ignoring stuff. When totems die come back to finish skeletons.
Nithlakh area, Diablo boss, Mephisto and councils, act 1 cathedral, act 3 kurast bazars areas - all easy and fun.
Duncraig - first part where no teleport is needed.
My current setup (nothing fancy, very few charms, but works ok):
