Higher mob count than many maps, good fast kill rate, central build, they recenty updated and resolved slow-ogre problem. And they added a decent pet at wave 35. Very good option overall.
Party: 1 TB Monk, 3 Summoners with guardian pets (huntress/monk)
Start TB about 100 kills in and it tends to last through the end.
Hint 5: nothing paths here
1 DST pointed at each crystal, except SW, cause the stack is close to it already.
If running 6 player, I'd recommend bringing in some DPS players (shooters) to pick off some guys. could also add another Summoner with EV and App pets.
