In accordance with the standard ranking system found in many fantasy novels, this system follows an F-A rank progression, with A being the highest. Beyond A-rank, there are additional, more powerful tiers, including S, SS, and SSS ranks:
S-Rank: Items of significant power, capable of unleashing immense energy, often with specific conditions or time limitations.
SS-Rank: Slightly more powerful than S-rank items, these come with fewer restrictions and offer greater strength.
SSS-Rank: Items at this rank typically possess no restrictions and have extremely potent effects. Example: Soldier's Uniform.
Above the SSS tier, two additional ranks exist:
Disaster Rank: Items in this category are akin to acts of God, providing immediate and overwhelming power. Example: Hestia's Guns.
Supreme Rank: Items of boundless power, their effects are immediate and unmatched, representing the ultimate divine force. No other item can surpass them unless due to a design oversight. Example: Kingsley's Lord Clothing.
Note: Owning a higher-ranked item does not guarantee victory in battle; the outcome is still heavily dependent on the skill and strategy of the user.
For example, while Hestia's Guns are classified as Disaster Rank, they are not all-penetrating. A strong defense, such as that of an S-rank creature, can still block the bullets. However, enduring a sustained barrage from such a weapon is another matter entirely.
