Left it running last night. I'm a proud new owner of a signet. Yay. That was frustrating!
I'll give as many details as possible.
Used monk char. 300%MF. Using the profile version where he explores the sewers. [A2 - Normal] Leoric's Grinder 1.2 Q4.1.zip
Added as much % movement speed possible.
Loot radius was 100. Kill was 50
5 games an hour. No gold looting to save time.
Used Giles new Trinity loot system.
I've tried this before without the NV stacks, seeing you could get more snakes, but no results.
My idea with using monk was tempest rush with this build
Monk - Game Guide - Diablo III
Monk doesn't yet use tempest rush to get around quickly like demon hunter does with vault. So I substituted the mantra with the evasion (movement speed rune).
This run would reap better results with that speed. Maybe if enough ask Giles nicely he'll put it optional on monk.
I was skeptical about finding this ring from the beginning. I'll post if I get another to confirm it wasn't just a fluke.
Thanks to everyone's contributions for this profile, it's a sure fire winner.
If I left anything out. Have a question? I'll gladly answer what I can. Good luck on being lord of the ring.
