What Is the Rarest and Most Expensive Solo Leveling Collectible?

The Black Heart that redefined Sung Jin-Woo’s destiny.

Gaining immense recognition soon after its release, the Solo Leveling anime continued the massive success of its manhwa counterpart. This series stands as a prime example of a well-executed power fantasy, adhering to a consistent formula without attempting to be something beyond its core appeal.

Within this alternate fictional reality, Hunters rely on remarkable weapons and artifacts to enhance their abilities and improve their chances of survival. While many of these items are valuable, certain ones achieve legendary status, becoming the most coveted possessions of Hunters and collectors.

Some of these artifacts are deemed so perilous that only the strongest guilds and National-level Hunters are entrusted with their protection.

Legendary Items in Solo Leveling

1. Demon King’s Longsword

Item Class – S Rank

Baran, a formidable Demon King, ruled over the 100th level of the Demon Castle and was also known as the Monarch of White Flames. However, by the time he encountered Sung Jin-Woo, his strength no longer matched that of the other Monarchs.

Among the many impressive items Baran dropped, one weapon stood out for its exceptional power and abilities.

In addition to providing an important damage boost, this sword possessed the unique capability to generate ceaseless lightning storms within a confined area, inflicting devastating harm on groups of enemies.

Since Sung Jin-Woo primarily wielded daggers, he chose to grant the longsword to Igris, further amplifying the formidable prowess of his loyal shadow warrior.

2. Black Heart

Item Class – Unknown

Among the most mysterious and symbolically rich artifacts, the Black Heart carries profound meaning beyond its raw power. This heart granted its wielder a staggering 100,000 mana points, rendering Sung Jin-Woo’s previous mana capacity of just 9,000 insignificant in comparison.

Beyond its practical advantages, the Black Heart signified a dramatic transformation for Sung Jin-Woo. No longer just a mere human, hunter, or player, he embraced a darker destiny.

As the chosen host—and eventually the successor—to the King of the Dead, this new heart bestowed immense power while simultaneously marking a deep, irreversible change in his very crux.

3. Kamish’s Rune Stone

Item Class – Unknown

Among the various artifacts in the series, runestones are highly prized due to their ability to grant Hunters unique powers. Even the most basic runestone commands a high price and remains heavily guarded by merchants.

Kamish’s rune stone, however, exists in a league entirely its own—much like the dragon from which it originated. Kamish, an enormous dragon, served as the final boss of the first-ever S-Rank Dungeon, unleashing destruction across America, leveling entire cities, and eliminating countless Hunters.

The remnants of this catastrophic event, including the rune stone, are under tight security by the Federal Bureau of Hunters, which now stands atop the site where Kamish was defeated.

4. Orb of Avarice

Item Class – A Rank

Artifacts that enhance magic power are rare, and even the most effective ones typically boost a user’s magic output by no more than 50%. Because of this, Mage Class Hunters constantly seek out such valuable enhancements. However, the Orb of Avarice far surpasses any other magic-amplifying item.

By doubling the user’s magic damage, the orb transforms even basic spells into highly destructive forces. This artifact provides an immense advantage to those who wield magic-based abilities.

Though Sung Jin-Woo frequently employs magic, his combat approach doesn’t revolve around destructive spells, leading him to entrust the orb to Tusk, a powerful Mage shadow under his command.

5. Kamish’s Wrath

Item Class – Unknown

Regarded as one of the strongest Hunters alive, Thomas Andre holds the top spot among all National-level Hunters.

His participation in the battle against Kamish granted him the opportunity to claim the dragon’s sharpest fang, which he initially kept as a personal keepsake. Later, he commissioned the creation of a weapon from the fang, though its size allowed only for a pair of daggers to be forged.

These daggers stand among the most powerful weapons ever crafted, possessing the ability to slice through nearly anything with ease. Since Thomas Andre had no particular use for them, the daggers remained untouched, awaiting a worthy wielder capable of handling their immense power.

6. Holy Water of Life

Item Class – S Rank

Though introduced early in the series, this item was not immediately accessible to Sung Jin-Woo. Before crafting it, he first needed to complete the entire Demon Castle, a task that required extensive effort and character progression.

The Holy Water of Life functions as an elixir capable of curing any illness, including the dreaded Eternal Slumber. Unlike ordinary potions, it does not restore health points but instead specializes in eliminating diseases and afflictions.

No comparable item exists, and it remains uncertain whether its ingredients can be obtained outside of the Demon Castle’s completion.

7. Cup of Reincarnation

Created by the Absolute Being

This relic possesses abilities that transcend all other known artifacts, granting it an unmatched level of power. Created by the Absolute Being, this magical cup holds the extraordinary capability to rewind time by an entire decade, effectively undoing all events that took place within that period.

However, only Rulers and Monarchs retain memories of the previous timeline. While the precise limitations of the Cup of Reincarnation remain ambiguous, it is known to have a restricted number of uses. As the series comes to a close, the cup’s final activation depletes its power entirely.

Though the way it was incorporated into the story’s ending sparked mixed reactions from fans, this plot device effectively tied up loose ends and brought closure to the series.
