Hello! I'm writing this guide because I have yet to see anything on Steam that has the current gear and class choices for end game play. This guide only has a select few builds that have been proven to work, and work well. It doesnt mean that they are the only viable specializations. I feel i've been fairly accurate in listing all of the items and their respective passives, but if im wrong please comment and I will gladly change the information.

I hope this guide helps you gear up and prepare for the horror that is NM4. As a side note, when first breaking into NM4 it is practically required that you run with atleast 3 DPS heroes to complete a map.

Added Apprentice Flamethrower Tower Build

New Players: Prioritize Defense Power/Defense Speed in your Stat Allocation, it should give you the most benefit when building.

Added Apprentice DPS

Stat Allocation:
200/200 Defense Health
Rest of points have no effect on walls


Spheres:
I believe these small spheres are standard

(S) Defense Health Sphere III, and V; Hero Health III

Medium Spheres have some wiggle room, and can be switched depending on if you are actively playing the character in a match or just using it to build. The inactive catagory really has no viable game changing sphere.

Active - (M) Shield Strength I, Cooldown Sphere I or Provoke Duration Sphere II
Inactive - (M) Defense Critical Chance Sphere in place of either aforementioned spheres

(L) Vengeance Sphere I (Inactive), Fight Me Not Sphere I (Active)

(U) Shielding Guard

Elemental Chaos Uber

Gear:
You will want atleast 2 pieces with Defense Health instead of Defense Critical Damage to increase longevity of your traps. Repairing them every wave can cost you upgrades.

Flamethrower Tower
I'm adding in this build because it is definitely viable for NM4 and i've seen it work. This tower is very strong, it is only weaker then traps because your towers can die and it requires excellent tower placement and perhaps a little luck to be successful.

Max Defense Range
