Item and Weapon Rankings

Normal - Normal Weapons and Items. 

Rare - Imbued with mana, so they will have one special characteristics.

Unique - An weapon/item that hold a unique characteristics that is only present within the weapon itself. The characteristic is impossible to duplicate. So this is a special type of weapons, but with only decent power. 

Legend - An weapon/item that was imbued by both the will and power of its creator and wielder in the past. A weapon that has been passed down by historical figures. Grants a temporary buff to its wielder.

Epic - weapon/item in this stage and above can only be created using mana imbued mineral like mithril. It has a certain extent of resistance and durability against physical and magic damage. Epic tier weapons and above are contractual based, so it can only be used to its full extent when a contact between the wielder and the weapon is established. The buff provided by the weapon will remain intact as long as the wielder doesn't die, or the contract isn't severed.

Mythical - A weapon/item created by the blood of mythical creatures. This weapons will hold certain characteristics that compliments its past holder or creator.

Chaos - A weapon/item of mass destruction, and is currently the most powerful weapon that the 3 faction has seen. Can potentially destroy large regions and cities when used at full force.

Demigod - A weapon/item made from the finest mana imbued minerals and parts of legendary creatures. Weapons/items at this stage and above can chose their own wielder, and kill/curse anyone who wields them without their consent. Offensive weapons/items of this rank can give a normal human to rival against Ultimate Class devils.

God - A weapon/item that was made specifically to kill or defy the gods, and requires a certain extent of strength before wielding it, or else it would corrupt the mind and body of its wielder.

Eternal - A weapon/Item that defies some, or all laws of reality, and can alter/bend it as it will. The strongest weapon that the Forsaken Faction can make

Celestial - Weapons/Items that can only be wielded by the primordial beings. This are special weapons that was specifically catered in accordance to their respective domains.

Unit Rankings

This ranks will only count those who stepped into the supernatural world:

Low

Mid

High

Ultimate

Satan/Seraphim

Lord

Transcendent

Demi God

God

Divinity

Cosmic

Celestial

Each rank is seperated by 4 layers which are beginner (low), experienced (middle), mastery (high), and peak.

This will be the general rankings, and I will compare this to how the alliance and the invaders rank their units. If you're wondering what rank Lucias is then he is at peak of Divinity Rank.

Skill Ranks

For battle skills (physical)

Basic

Normal

Advance

Master

Peak

For battle skills (magic)

Elementary

Basic

Normal

Advance

Legendary

Transcendent

Magic skills can start from elementary and advance to Transcendent. Some skills will start off strong and will not upgrade no matter what. Skills like Time, Spatial, and Contract magic are all at the transcendent rank at the start.

Magic is also divided into categories

Attribute Magic

Demonic Magic

Divine Magic

Reality Magic

Primordial Magic

Origin Magic

Each have their own strengths and weaknesses but the strongest one are Origin Magic, there are only 3 magics in that category, and those are...

Destruction

Creation

Existence

Some attribute magics can ascend to Primordial Magic if certain conditions are met.

Some skills aren't upgradable and some have their own special upgrades. This skills are called Accessory Skills, since most of them are always passive, and give a substantial buff to its wielder. For example:

Diamond Skin

High-speed thought processing

Parallel thought processing

Sense

Reflex

Are all accessory magic and the most common ranks in accessory skills are:

Normal

Enhanced

Supreme

Additional Ranks

Each individual in the DxD dimension is also seperated by number ranks, which are based on their individual strength. This will only count the beings in the DxD dimension, not the beings that Lucias brought back with him. Of course, the helltaker characters belong to this ranks, since I made them part of the DxD series.

For example:

#1 Lucias Frey

#2 Xoasis

#3 Trihexa

#4 Great Red

#5 Ophis

#6 Lucifer (Helltaker)

#7 Beelzebub (Helltaker)

#8 Justice (Helltaker)

#9 Judgement (Helltaker)

#10 Azazel (Helltaker)

This are the top 10 most powerful beings currently in the DxD dimension. But if Rimuru, and the other True Gods joined, then the rankings will significantly change.

There are more things to discuss, maybe I'll absorb 2-3 more chapters to explain everything.
