what is the best class for climbing and also what kind of skill or main damage source did they use?

the thing is, players have used all 3 classes and many different builds to climb floors.
Crushing Flames on builds is probably the easiest way to climb floors, and using only Crushing Blow is second.
then there’s using a Main & Hireling to get more DPS when climbing floors.
a Plagued or Arcanist build is another way to go, if you play it the right way.
the thing is, the higher the floor, you end up trading defense for offense, unless you use defense & speed to get to the Cartographer fast to kill it and go to the next floor without having to kill all the monsters.
