Build Description
This is a modification of Schmiergeld's Ascension Build that should make it easier to farm with less maintenance.
The stats listed are roughly the stats I expect where it should run smoothly. Lower stats might be able to do this build too.
Use a Boost-Summoner with Huntress + Monk Guardian on the LT stack and if you want another Boost-Summoner with Apprentice + Huntress Guardian on the DST/ Mortar stack.
The strength drain auras might need repairs during the wave depending on your stats. The rest usually works like a charm.
Starting around wave 17 and restarting as soon as you hit wave 29-31 or you're getting into trouble tends to net the highest amount of ults/hour.
