If you ask me which class deserve your all D3 Gold, I would tell you- Barbarian. You can spend the least money to get the most powerful hero. Wizard is pretty good at the control and the AOE damage, it is not so efficient compared with Barbarian in solo items farming. Monk can never match Barbarian with the damage with the same amount of gold. Demon Hunter is too fragile in high Monster Power. Witch Doctor never equals with efficiency.
This time we would tell you how to build a 10 MP Barbarian with two million gold.
Gems: One Radiant Star Amethyst in the Helm, one radiant Star Emerald in the weapon, three Radiant Star Ruby in the Chest Armor and two Radiant Star Ruby in the Pants. All these gems would cost you around 160 million Diablo3 Gold.
Weapon: Skorn is the Number One choice for Barbarian. You should search with + Strength, Critical Hit Damage, Life Steal and Socket. This would cost you around 150 million to get a top one.
Rings: Hellfire ring could give you over 200 Strength, if you are lucky enough, you can get Vitality, critical hit damage, attack speed and critical hit chance. This require nothing from you except luck. As to the other ring, you could get one Stone Jorden or something rare rings with attack speed, Critical hit damage and Critical Hit chance about 10 million.
Helm: Mempo of Twilight with +160 Strength, +80 Vitality, +70 Resistance to All Elements, Attack Speed, +11% life and a socket would cost you 150 million gold.
Gloves and Chest Armor: These two parts I would recommend Immortal King’s Eternal Reign and Immortal King’s Irons. The set would give you +60 all resistance with 160 million.
Belt: Witching Hour give the Attack Speed and critical hit damage with price of 80 million.
Bracer + Pants: Lacuni Prowlers and Inna’s Temperance would give you +24% movement speed with price of 160 million.
Boots: Ice Climber can offer you high Strength, vitality, all resistance and life. What is more important, you can insert a gem in the socket with about 100 million.
You have to spend around 1.5 Billion on all these top Diablo 3 Items. The Bracers and Amulet you can turn to the Black Smith. I guess 500 million gold are pretty enough for you to get top item results.
