The following build is the best Wizard build I could find. It’s a strong DPS build and will work well in both cooperative/group and solo play. It’s geared towards doing high damage with abilities that you can use when you need to get out of trouble or stay alive a little longer to do more damage. As with all the diablo 3 builds on this site, this should act as a basis for the build that works best for your gear and situation.
This build requires level 57 but there are a few adjustments you can make to bring that level requirement down: http://us.battle.net/d3/en/calculator/wizard#beXROS!XYc!bcabYZ
For the primary slot Shock Pulse with Piercing Orb is an all around powerful cast to use when you’re out of Arcane Power. This selection is based on maximizing damage. If you think you have another need feel free to swap in another signature spell. If you’re not level 57 consider using either Disruption or Death Blossom.
Arcane Torrent with Cascade is a relentless AoE that is available at level 57. This effect will chain throughout an entire group if they are already low health. You’ll find yourself using this as your primary ability.
Crystal Skin with Crystal Shell is a pure defensive ability, perfect for the defensive slot. With a 15 second cool down it allows you to go absord 21,000 damage for 6 seconds. This is an essential survival skill that will save your life and save you time.
Venon Hydra will spit poison acid, leaving a pool that does damage to enemies that cross it. The Hydra is generally a low damage output companion but with the pool of poison you can draw the enemies through it and get extra damage without doing much work.
Energy Armor with Force Armor is another create defensive ability, giving you a bout of high armor at the cost of Arcane Power and also capping the total damage with the Force Armor skill rune. If you’re not level 54 yet Absorption will help mitigate the lose of Arcane Power.
Instead of using a traditional Mastery skill like Archon, consider grabbing Magic Weapon with Force Weapon which will net you a +15% damage bonus whenever it’s active (which is pretty much all the time). This will enable you to focus on your other abilities while also benefiting from this slot all the time. This is a crucial aspect of this build.
There are a lot of great passives to choose from. Here are the ones that work the best with this build: Astral Presence will help mitigate the lose of Arcane Power from Energy Armor or just give you extra Arcane Power the rest of the time. Glass Cannon is a classic + damage at the cost of survivability passive. If you’re having trouble staying alive this is the first passive to swap out. Prodigy gives your signature spell (in this case Shock Pulse) the ability to generate 4 Arcane Power everytime it deals damage. This makes the Wizard play more like some of the other classes like the Demon Hunter.
