Dungeon Lootr Boss Rush: Floor 40 Class Items & Solo Setup

How to enter

Boss Rush is an endgame mode separate from the story dungeons and from Challenge Dungeon waves. Creator guides put the unlock at roughly player level 60-67 (the listing does not print a number), and every entry costs a ticket, which mostly comes from Challenge Dungeon rewards. You can queue solo or in a party, and you select the boss lane when you create the lobby.

The floor plan

Floors	What matters
1-39	Warm-up. Learn patterns; class items are not the point here.
40-99	Class-item window. The higher the floor, the better the drop chance.
100	Main boss: 8-18 fragments of the lane boss for Forge crafts.

Bosses scale with floor and every floor is a boss encounter, not a wave.

The three lanes

Lane	Class item	Forge craft
Sukuna	Cursed Shrine → Cursed King	50 Sukuna Fragments
Gojo	Infinity Core → Honored One	50 Gojo Fragments
Asta	Anti Magic class item	50 Asta Fragments

Commit to one lane until it pays out. Honored One first if Unrestricted is your long goal; it is both a kit and the material for that chain.

The published solo setup

Solo clears that finish in about 13-15 minutes use a ranged kit:

Class: Witch Gunner.
Aspect: Ruin (repeated M1s stack up to +75% damage taken on one boss). Blaze or Alacrity are the fallbacks.
Armor and helm: ranged-damage affixes.
Rings: bonus damage, critical damage, critical rate, life steal — rings carry the most offensive lines in the game.
Stat points: all Dexterity.
Title: Iron Sights (17 Dexterity); God Hunter is the broader alternative.

Keep distance, keep firing, move on telegraphs. If your clear is 30+ minutes and shaky, fix damage at the Forge before spending more tickets.

Repeat-farm checklist

Farm Challenge Dungeon for tickets, Aspect Gems and Protection Scrolls.
Upgrade the clear-speed weapon and rings before a deep climb.
Enter with a ticket, commit to one lane.
Push past Floor 40; aim for Floor 100.
Bank fragments and materials the moment you are out.

Mistakes that cost tickets

Entering under-levelled with a soft kit.
Stopping before Floor 40.
Ignoring Floor 100 — fragments stall every craft.
Random lanes every ticket.
No Aspect, or the wrong stat column.
Unspent Reforge Stones before a climb.

Drop rates for class items and the exact fragment count are community-reported; ClickBytes has not published them, and a patch can change the window.
