I have tried that a lot of times, I ran that map probably like a hundred times, and I mostly had downtime, because the next mob does not spawn fast enough in most cases, so Breast Ripper ends before the next mob can spawn.
You need a lot of investment in Breaking Wheel and have high STR to actually pull that off when alternating both skills.
The only way I can see Inquisitor actually pull off the no-downtime run is if you put Zealot and Dievdirbys in your build. Then we’re not talking about Inquisitor alone anymore,though, but about a specific build.
Since this guy is talking about a slave, I doubt he plans to invest into many skills and a really good set effect/weapon/gems/etc to clear the CM at higher stages.
About Monks Energy Blast, yes, it doesn’t deal as much damage as the Breast Ripper/Breaking Wheel combo on CM 6&7, but it’s still possible to clear a wave of CM 6/CM 7 mobs at OW 14 with Energy Blast, I usually used Breaking Wheel + Breast Ripper first, then I had about 20 seconds downtime left on Breast Ripper, which made me spam Energy Blast to clear the freshly spawned monsters(note that we’re talking about invested characters now to clear CM 6+).
It’s also pretty efficient since you hit all monsters on the screen in that passage close to the OW 15 exit. Once Chaplain gets the new attribute for Capella,this will become even more of a walk in the park, then I can just use Breaking Wheel for the bonus physical damage boost stacks and spam Energy Blast to nuke mobs like no tomorrow.
