I tried it myself with 5-6k~ stats and it worked, but the only problem was that my builder monk had 2.5k damage, orcs could get the bottom left crystal on last wave due not enough aura damage. Increasing damage to 3.5k worked perfectly and no crystal was damaged even once by a random mob. Though, since my attack rate is low, increasing attack rate instead would work better.
Since the build doesn't provide any specific stats I'll provide my ones which worked with that build.
Monk: 2k / 3.5k / 4k / 1.5k
EV: 4k / 6.2k / 3.6k / 3.8k
Apprentice: 2k / 7k / 2.7k / 3.3k
Hunter: 2k / 4.6k / 2k / 2k
