Wave 1: Build all harpoon, swap to monk with genie to quick gain mana to build stack aura (Ensare, Lightning, Streng Drain) in each choke point.
Wave 2: Swap to the Series EV, build all buff beam like layout. Remember, careful when u place buff beam, u will need space to build minions after that.
During wave 2 and Wave 3: Use the summoner to stack minions, at least 600 mana in ur hero to do the trick. Place 4 archer, 1 mage, 1 spider in each choke point except the crytals near the bridge (that will have only 4 archer). That is the backbone of the build, leftover DU and MU, u can customize like what u want.
Good luck!
It can be afkable if u max 3star the aura and the buff beam. buf not for long, around 10 min, u should repair them, or u just use a imp or engineer to make afk time longer .
The require stat is my stat on doing this build. u can try lower stat around 200, but it need more work to do.
If u have any question, just comment, i will help if i can
