oh, well, that is different. because I am stubborn, I didn’t want to use other players builds, and wanted to see how far I could go with my own ideas. but a lot of what I know is from builds and ideas shared by other players, so that saved me from making a lot of mistakes and wasting Crystals. I stopped climbing floors for awhile to get 3 of my Characters to level 99 for use in PVP, and am now Ascending 2 more Characters for them to have all 6 Perks. it is a lot of work, but I am learning a lot. I used Wizard a lot, so I have a lot to learn about Warriors and Rogues.
after I posted this, I have climbed to floor 980’s M3, but I wanted a Farm Build that could do well at floor 1,000. then I would know for sure it could farm great at floors 510 or lower. that would make it easier to get stuff for when I climb floors 1k+, 2k+, or even higher.
here are a bunch of posts talking about Billions of Damage for rogues. some of the builds are old and might need some tweaking because of Patch Updates, but hopefully they will help you reach your goal of a Billions of Damage Rogue.
