If you want to deal some moderate AoE damage, I will suggest you use Electrocute as your basic damage skill with the Crimson Runestone. If you want to increase the damage gained, Obsidian Runestone is a good choice. As for escape skill, I think Teleport can help you gain it from distance when cornered. If you want to slow down the enemies, you need to use Slow Time which is a great harassing skill that can give every team member a great advantage when playing in group. Together with Hydra, you can make some fair amount of damage while struggling to get out the area. If you master them well, you are able to earn enough fast Diablo III gold for buying some good Diablo 3 items for sale for your Diablo 3 accounts.
For ultimate survivability, you should choose Diamond Skin to help you out of tough situations. But I have to remind you be careful to use this skill. Except for these, you can use Temporal Flux, Passives Evocation and Unstable Anomaly to complete this build with high survivability with some great harassing potential to earn someDiablo 3 gold for sale for you to buy Diablo 3 items.
If you want to be Wizard with best AoE damage, Wizard is definitely the best DPS class in Diablo III. Wizard can output tremendous damage and can literally eliminate enemies in a few seconds. It is excellent at killing creatures in small numbers at a time. Therefore, if you want to be elite as Wizard, you need to find great AoE builds to clear your path. In my builds, you need to use Electrocute enhanced by the Golden Runestone to start off. As it is the main spammable skill and an Arcane regenerator, you can choose some other skills, like Slow Time, Teleport which are the core of the build. Teleport is a good skill as it can help use some powerful AoE powerful skills. For passive skills, Evocation can reduce cooldowns by the same percentage and Astral Presence can ensure you have abundant Arcane Power.
