Hi Woerner.
As others have pointed out, you aren’t following the guide.
Thing is, you can’t try and get close to the suggested items and rolls. You need the exact specific items with the exact specific rolls. Unless the guide mentions it, substitutions aren’t allowed. For example, you’re using Vanished Peak in the Cube, but that’s for a Slam build, not HOTA; you need Gavel of Judgment in the Cube or your HOTA deals no damage! You also can’t use Nemesis in the build!
So, for you, step 1 is to read the New Player’s guide: [Guide] New + Returning Player's Guide (Season 20)
That will explain the basics of gear and rolls, because a lot of your gear is more or less garbage and shouldn’t be used–at least not for pushing. After you’ve read that and farmed better gear, re-read the R6 HOTA guide, and pay close attention to the sections that detail gear and game play. The build is very tricky to master, and if you don’t play it 100% perfect, you won’t deal any damage.
If you’re a new player, you may want to shelve R6 HOTA until you have more gear and skill. In the meantime, I recommend Fire EQ or IK HOTA – both are easy to play and provide a lot of bang for the buck.
