Hot monkey a stick.. Awesome script! Got it working in a couple of minutes with a few tweaks.
Ran it for 30 minutes got 222k and one yellow in 38 runs. 72 closed. With 330%gf, 48mf, 16+ Pick up radius and ~18k unbuffed ~25k DPS (buffed with BBV)
Here is what I found to useful after watching it run:
I replaced skill 3 with Acid Cloud (Corpse Bomb), Right-Click mouse button with Wall of Zombie (Unrelenting Grip) and Skill 2 Fetish Army( Fetish Ambush)
One cast of Corpse Bomb does 200% weapon damage, this will effectively take out the white mobs around Sarkoth also a chunk of his health, and with Wall of Zombie Sarktooth will get boxed in along with where the white mob died. A few more Splinters (~2 cast) will finish him off without him moving. You have around 20k Buffed DPS to pull this off since the white mobs usually 20-40k health. Lower should be Okay too since wall of zombie will last a couple of seconds, and you shoot darts immediately after the cast sequences anyways.
The idea is that the gold and item drops around in a smaller area. So you can turn on the higher pick up radius function and use the shorter route without the actual bonus pick up radius. Time saved = gold gained amiright

?
You can still pick up ~100% of the gold each run with pick up radius like maybe around ~5-10, Once in a blue moon you might miss one or two hundred gold.. but I'd take the latter.
The Fetish Army with Fetish Ambush rune:
I notice when the the cellar door is closed, as the toon is casting town portal it can get interrupted by near by zombies and quilfiends sometimes, and you end up waiting a couple of seconds to retry again.
The Fetish Ambush rune does 250% damage per fetish summoned around the WD, this protects the toon when he is casting the portal.
Happy botting, and thank you zeenexx again for making such a great bot!
