Ranking and Grading

In the Tower weapons, Inventory-Items, Wand, Pockets, Lighthouses, Mobiles and even the different skills mastered by Rankers and Regulars (Eg; Intelligence, Weapon Mastery) are all given ranks according to their level.

Both Rank and Grade are used in this relation and bear the same meaning.

We do not yet know by who or how these ranks are decided. But it is safe to assume that a ranker's or a regular's ranking will change as he/she gains strength and obtains more skills.

This Rank and Grade is not to be confused with the (overall) Rank that only Rankers have and which is given by the Ranking Administration Office.

The Levels of Ranks
The ranking system goes from SS+ as the highest and down to 10F as the lowest. The scaling goes as following (it applies for classification of items/weapons/etc too):



It is assumed that any Ranker's final Grade being above A makes them a High Ranker.

Known Examples of Ranked Skills of High Rankers, Rankers and Regulars:
Known examples:

High Rankers:

 * Yu Han Sung overall 8A

Known Examples of Ranked Weapons and Items:
It is unknown how weapons and other items are ranked but it likely linked in part to the quality of raw materials that were used in their creation. For example, the Lighthouses used by Regular class Light Bearers in Part 1 consisted of low purity Suspendium that required shinsoo manipulation to float and move. This is in contrast to one of Hatsu's swords which was capable of floating without any use of shinsoo to power it. In the case of wands, it is known that the contract of a wand is one of the main factors in determining its rank.

A-Ranked weapons and items are extremely rare, to the extent that even rankers seldom own them. So rare are the A-ranked and above weapons and items that only High-Rankers could be expected to own more then one. To illustrate just how rare and precious A-Rank Weapons/Items are, one may notice that none of the following rankers; Lero-Ro, Lo Po Bia Ren, or Quant have been seen using one.
 * White Oar: the only S+ Rank weapon in the Tower (a Sword)
 * Golden November: a S-Rank weapon (weapon type unknown).
 * Black March: a A-Rank Needle ( w hen ignited ).
 * Green April: a 7B-Rank Hook (most likely A-Rank when ignited)
 * Narumada: a 7D-Rank Sword.
 * Carrier: Of the 10 Carriers which were created, 3 are A-Rank and 7 are B-rank. Adori Zahard owns 1.
 * Vagnil: A spear which can be used as a bow (probably D-rank or C-rank), turns into a B-rank when ignited.
 * Opera: Rank currently unknown but likely S-Rank, considering it's one of the the highest grades of Lighthouses in the Tower.

Notes and Trivia

 * Notice that it seems as if the normal numeric system is not used for S or higher rank weapons. Maybe because there are so few S or higher rank weapons.


 * Since all regulars receive an E-Grade pocket when entering the tower, it seems safe to assume that E is the lowest kind of pockets.
