Dungeon Lootr: How to Unlock Sukuna and Asta Classes

The exact Boss Rush fragment counts, Forge recipes, and floor thresholds that unlock Cursed King and Anti Magic.

The exact Boss Rush fragment counts, Forge recipes, and floor thresholds that unlock Cursed King and Anti Magic.

Cursed King (Sukuna) and Anti Magic (Asta) are two of the most requested chase classes in Dungeon Lootr, and neither one comes out of a class spin. Both are gated behind Boss Rush, and both end the same way: a pile of 50 fragments turned into a class item at the Forge.

Quick answer: Reach player level 67 to enter Boss Rush, farm the Cursed King boss for 50 Cursed Fragments and the Anti Mage boss for 50 Anti Magic Fragments, then craft the Cursed Shrine and the Anti Magic Claymore at the Forge to unlock each class.


Boss Rush requirements before you start farming

Boss Rush is the only mode that feeds either unlock. The mode opens at player level 67 or higher, and it runs on tickets, so you cannot brute-force attempts. Confirm the unlock condition on the live Boss Rush screen before you commit, since Early Access values move.

Clear speed matters more than floor number here. A run that ends before the reward phase costs you a ticket and returns nothing, so finish your regular extracts, upgrade your gear at the Forge, and add Vitality if survivability is the reason your runs die. Floor skip tickets let a group jump straight to the boss encounters instead of grinding filler floors.

Cursed King and Anti Magic unlock requirements compared

Both classes have two paths. The class item itself can drop directly from Boss Rush at floor 40 or higher, with drop odds improving the deeper you go. The Forge craft is the predictable path, and it is the one most players finish first.

Fragment payouts scale with the boss you kill. The main boss on floor 100 hands out roughly 8 to 18 fragments per relevant kill, and repeat runs against the Cursed King boss have landed in that same band, with single fights paying out 8, 13, 16, and 14 fragments. Four good boss kills can therefore finish a 50-fragment craft.

Note: pick one lane. Boss Rush tickets spent chasing Sukuna, Gojo, and Asta at the same time stretch all three farms out. Finish one craft, then switch targets.


How to unlock Cursed King (Sukuna)

Enter Boss Rush with the Cursed King lane selected. Running in a duo speeds up the boss phases considerably, and floor skip tickets cut out the filler between encounters.
Kill the Cursed King boss and collect Cursed Fragments. Each successful kill drops a chunk of the 50 you need, so track the running total in your inventory rather than counting runs.

Open the Forge crafting tab once you hold 50 Cursed Fragments and craft the Cursed Shrine. Check the live recipe cost before you spend, since the coin and material side of the recipe can change between patches.
Equip Cursed King from the Classes menu and test the kit. The class is melee-focused, built around Cleave Rush, Slash Combo, Cleaving Rush, and Fuga, with Domain Expansion (Malevolent Shrine) as the ultimate.

How to unlock Anti Magic (Asta)

Switch your Boss Rush target to the Anti Mage boss. The lane works the same way as the Sukuna route, but the fragments it drops are Anti Magic Fragments and they only count toward this craft.
Repeat boss kills until you bank 50 Anti Magic Fragments. Higher floors pay more per kill, so push upward once your clears are stable instead of parking at the minimum floor.
Craft the Anti Magic Claymore at the Forge. The recipe screen lists the fragment requirement alongside the other costs, and crafting the weapon is what actually unlocks the class.

Set expectations before you spend the tickets. Anti Magic has no ultimate and no unique title, so the payoff is the class kit itself rather than an extra damage window or a stat-boosting title. Community rankings tend to place it a tier below Cursed King.


Stat allocation for Cursed King damage

Cursed King scales with Strength, which drives physical and melee damage. A full Strength build produces the highest numbers on paper, but you only want to go that far once your runs stop ending early. Buy Vitality the moment you are dying before the reward phase, not before.

Dexterity and Intelligence do nothing for this kit, so leave them alone. Aspects come after the stat plan is settled, because rerolling gems before you know whether your problem is damage or survivability wastes materials.


The Cursed King title at mastery level 50

Unlocking the class is not the end of the Sukuna chain. Once Cursed King reaches mastery level 50, the Sukuna NPC sells the matching Cursed King title for 1,000,000 coins. It grants +8 Strength, +8 Dexterity, +12 Vitality, +8 Intelligence, and +5 Luck.

Treat the title as a late purchase. Coins spent there are coins not spent on Forge upgrades, and the title does nothing for you until your Boss Rush clears are already consistent.


How to confirm the unlock worked, and why it fails

The craft is confirmed when the Forge consumes the 50 fragments and the class appears as a selectable, equippable entry in the lobby Classes menu. If the class is not there, the craft did not complete.

ProblemCause and fix
No class item dropsYou are below floor 40. Class items only drop from floor 40 and up, and odds rise on higher floors.
Fragment total stuckYou are killing the wrong boss. Cursed Fragments come only from the Cursed King boss, Anti Magic Fragments only from the Anti Mage boss.
Runs end with no rewardSurvivability, not damage. Add Vitality and upgrade gear at the Forge before spending more tickets.
Forge craft greyed outFragment count is under 50, or the recipe’s coin and material cost is unmet.
Progress feels slowTickets split across multiple lanes. Commit every run to one fragment type until that craft is done.

If you only have the tickets for one of the two, Cursed King is the stronger finish. It has the ultimate, it has the title, and community rankings park it at the top alongside Unrestricted. Anti Magic is a fine second craft, just not the one worth burning your ticket stock on first.
