Rankings:

The World System of Terra Sol divides monsters, classes, and items, into special rankings depending on the strength, value, or rarity, of the item in question. 

Racial rankings:

A racial rank tells about their position on the evolution chart of the race in question. All races are classified by these ranks. From the lowest of G to the highest of A, or even the special rank S. These rankings also tell about how high the Race Level can be.

When an individual reaches the highest level for that race, they can evolve into a new race that is one rank higher. Skipping ranks are not possible. 

• Rank G:
  • The lowest possible rank.
  • Races of this rank include normal small animals such as rats and housecats, plus a few monsters such as the Grey Demon.
  • Racial Level Limit: Lv.10

  • Races of this rank can be a potential threat to individual humanoids.

Status rankings:

The natural, average Strength values¹Meaning status values for the STR, VIT, MAG, RES, SPD, and DEX stats of creatures recorded in bestiaries are shown with ranks to show approximately how high those Status values are.

The INT stat is calculated a bit differently. 

As it is different between each individual, the LUC stat is not assigned to bestiaries. 

In bestiaries, there are also used rankings to show how much damage such a creature can do, as well as rankings for the rarity of these races.

There is also given an additional + or -, depending if the individual is a little stronger or weaker than the value that rank represents.

Note that the forces used for the Danger Ranks are based on regular, rank E humanoids.

The rankings are as follows:

• Rank G: 
  • Strength Values: around 10 points.
  • INT Values: from 0 to 10 points.
  • Rarity Rank: Easily found creatures. The kind that can be found everywhere.
  • Danger Rank: An adult human can take care of these.
• Rank F: 
  • Strength Values: around 40-to-60 points.
  • INT Values: from 15 to 30 points.
  • Rarity Rank: A little rarer than rank G creatures, but one can expect one of these in environment-friendly habitats.
  • Danger Rank: An adventurer with some experience can take care of these, as long as they are careful.
• Rank E: 
  • Strength values: around 80-to-120 points.

Item Ranks:

Just like with living creatures, the performance of an item can be divided into several categories and rankings.

There are three different categories, each explaining the value of the item:

• Rarity: The rarity of that item. This category shows how difficult it is to obtain this item.
• Quality: The quality of the item, meaning how well its effects are. Two items of the same kind, but of different quality, will have different effects.
• Durability: The durability of the item. The item is considered broken when the durability reaches 0.

An item's durability is described with precise numbers, while the quality is shown with the same system as racial ranks. For example, an Iron Sword with a quality of G is as good as thrash, while the same type of Iron Sword, but with a rank of A, can be used to fell trees in a single swipe. 

Item rarities are explained as noted below:

• Normal (No):
  • Items that can be found everywhere.
• Rare (Ra):
  • Items that require some searching to obtain.
• Epic (Ep):
  • An incredible item that requires a long search to find.
• Legendary (Le):
  • A first-class item that is made with only the finest of materials.
• Godly (Go):
  • Sacred treasures made by the gods or someone with equal prowess in crafting.
  • They have a fixed owner, therefore they cannot be used by others and they return to their owner if stolen.
  • They cannot be destroyed, either by being literally unbreakable or because of the ability to instantly repeating themselves after being destroyed.
  • While possessing extraordinary powers, their rarity is exceeding said power,
• Extra (Ex): 
  • Items that can be anything from joke items to superb stuff of the utmost quality.
  • They are the result of master crafters, or the Ultimate Gods themselves, going a little too far, or simply screwing around.
  • Like with Godly items, they cannot be stolen, nor destroyed. The reason why varies between the different items.
  • Some Extra items may be rewards for special Quests.

Alvatria's comment: I simply loved to make that tentacle-summoning grimoire before.
