The purpose of this build is to blow through most of Normal and the beginning of Nightmare difficulty. Most of it is unlocked in the late teens but some of the skills are not completely unlocked until level 30 when you enter Act IV of Normal difficulty. The build’s primary focus is doing careless damage. I recommend you equip the highest level Amethyst you can find in your bow, for health regen, and follow my Power Leveling Tips Guide.
I also stack + Experience and put a Ruby in my helmet to increase total XP gained as I progress. This will keep you several levels ahead where you would be otherwise which will improve your stats and give you access to more gear off the auction house. I try to keep my 1-Handed Wand and Offhand Magic Source of high quality.

Magic Missile is the signature spell. I don’t use Prodigy so I might be casting this more often than others. I’ve got the damage of this spell buffed with Charged Blast so that it can one-shot trash enemies or anything with low life.
I do most of my damage with Arcane Orb. Despite the high Arcane Power cost (counter this with +Arcane Power on Crit gear) this spell does a lot of damage when placed in a group of enemies properly. I usually run into a group with Frost Nova and then cast a few Arcane Orbs to weaken the group and then finish them off with Wave of Force. Arcane Orb is runed with Obliterate to increase it’s effectiveness.
Frost Nova is used to freeze enemies in place so that they are that much easier to hit with orbs. Cold Snap reduces the cool down so that I can use this more often.
Wave of Force is used to weaken enemies or finish them off after I’ve thrown out a couple Arcane Orbs. With proper gear this will one-shot big groups of white enemies. First drop a Frost Nova, then wait for the rest to group around and then use Wave of Force to get a Massacre XP Bonus. I runed Wave of Force with Force Affinity to reduce its cool down and Arcane Power cost.
Familiar with Sparkflint offers a 12% damage buff. I like damage increases since I am trying to be able to one shot as many things as possible with Wave of Force and Magic Missile. Magic Weapon has the same exact purpose except it is harder to remember to keep up since there is no visual queue that it’s active.
Passives: Glass Cannon is a straight up damage buff while Astral Presence and Power Hungry make sure that I have the Arcane Power I need to take advantage of my high damage.
Considering I used this with decent gear the addional +12%, +10% and +15% damage help a lot. For bosses you can swap out Arcane Orb for Ray of Frost and Power Hungry for Cold Blooded. This will increase your Ray of Frost damage another 20% which will destroy whatever boss you’re facing.
The key part of this build is that it’s used while you can still afford to take damage early in the game. It’s also important you use the Templar for heals and have an Amethyst in your weapon for even more heals. +Experience and +Arcane Power on crit are extremely helpful for this build.
