Rather easy build, I can be completely AFK. Not aware of minimum stat requirement. But you can see my stats in the video.

Any hero shouldbe possible to play during the waves. The most important thing is to have enough duration on your Poison Traps, you'll see in the video that the goblins are getting very close to the crystal, never had any hit on the crystal yet though after 15+ runs. Using rate gem on Monk in the video below.

I tend to go with more Rate on the Apprentice than most other players, see the hero attibutes in the video, and the reason for this is because I want faster trash kills, And since the DSTs are overkilling trash enemies by a lot, much damage is going to waste.

Fusion Towers:
DST.
Ensnare Aura.
Poison Trap.
