It's not a great "speed" armor farm, in the end we found about 241 kills per minute.  About half as much as the comparable Royal Gardens.  The waves here lack numbers, that's why we only run it from 32-35, because waves 34 and 35 are the only significant numbers (1,900 mobs roughly, whereas most earlier waves have like 800 or less).  On the Pros side, there are 10 chests to open each wave, and that is significant.  There is also good end of run loot from the map in the form of Soul Disolvers and Goblin Wrenches and Minimechs and accessories.

The build is pretty safe,  

Party: 1 Tower Boost Monk and 3 Summoners with guardian pets (monk/huntress)
