Combat Professional: The full name of the combat profession is divided into a total of ten mainstream categories based on the basic combat class of the initial awakening, namely 'Warrior', 'Mage', 'Knight', 'Archer', 'Stalker', 'Priest', 'Druid', 'Possession', 'Defender' and 'Summoner'. In addition to these 10 mainstream categories, there are also nearly 100 partial categories or categories with a small spread.

Sub-Job: A class that specializes in Life Skills or Combat Support Skills, and there are eight main categories: 'Blacksmith', 'Apothecary', 'Enchanter', 'Mechanical Engineer', 'Trap Master', 'Esoteric Scholar', and 'Logistic'. In addition to these seven mainstream categories, there are about 20 kinds of partial and niche categories.

(Being a combatant does not mean that you cannot become a deputy, and the same is true for those who become deputies, the difference is only in the division between the main and the balance.) ）

(Among them, both the combatant and the deputy have a level, the combat officer is the adventure level, and the deputy is the mastery level, and the rank division is the same: the first order (LV.5-LV.10)→ the second order (LV.10-LV.15)→ the third order (LV.15-LV.20)→ the fourth order (LV.20-LV.25), → the fifth order (LV.25-LV.30), → legendary (LV.30-?) ））

(Each tier needs to complete the first tier to progress to the first tier of the next tier, which is the same level but represents a different level.) Among them, the third level is the elite level, the fourth level is the mentor level, and the fifth level is the grandmaster level, and reaching LV.30 but not stepping into the legendary level is called the quasi-legendary level)

General term for basic combat positions: For example, 'warriors' refer to those who use their basic combat positions as 'warriors' for subsequent transfers. For example, if the current combat class is 'Lorain Berserker', if others do not know the specific combat job name, it will generally be referred to as the "Warrior" combat class.

'Road' general name: as long as the basic combat positions are the same, even if the sequence of subsequent inauguration is different, but as long as the ability is similar and the combat methods are similar, they will be collectively referred to as a certain 'road', and each basic combat job will extend into two or three mainstream 'roads' at least seven or eight, for example, the follow-up mainstream roads of the 'warrior' are 'swordsman', 'berserker', 'technical fighter', 'demon warrior', 'heavy warrior', 'combat master' and ' There are eight types of weapon masters, and a hundred other 'paths' that are called non-mainstream or extremely niche.

Generic name for the inauguration sequence: For example, a fighter who has been inaugurated in the 'Nightmare' sequence and subsequently transferred to a career can be referred to as 'Nightmare' no matter what level they reach and what the name of the profession at that stage is.

Segmentation of combat positions: Under the same large category, because the sequence of employment after LV.5 is different, the subsequent job transfers are naturally different, and many distinctively homologous combat positions will be developed and extended, so the names of all combat positions in different races and under different circumstances are not uniform most of the time.

(Take a chestnut.) Chen Yuan can be called the 'defender' directly, or he can be called the warrior of the 'defender' department, or he can be called the 'shield armor' in the four mainstream 'paths' of the defender, and of course, he can also be directly called by the sequence name of 'absolute defense'. ）

(However, in most cases, if you don't take the initiative to reveal your sequence name or the chosen 'road', others will generally use the general name of the basic combat class or the guessed name of the 'road' based on the characteristics revealed on your body, for example, when the enemy target sees the large tower shield in Chen Yuan's hand, they naturally think that Chen Yuan is a 'defender' based on their first impression, and guess that the selected 'road' is from the fact that he first opened the shield array for protection.) Of course, these subjective or guessed 'titles' are sometimes wrong, and this is also common. ）

Natural elements: wind, fire, water, earth, and thunder.

Eternal Element: The three systems of light, darkness, and chaos.

Energy: Arcane and Psychic powers.

Special: i.e. soul, poison, cause and effect, truth, etc.

(In addition to energy and particularity, each of the natural elements and the eternal elements has a different number of extended secondary series, for example, the extension of the 'water' system has the 'ice' system and the 'fog' system.) ）

The quality of equipment: from low to high, there are seven divisions: gray inferior, white common, green excellent, blue perfect, purple rare, red legacy/legendary, and orange epic, of which epic is also called 'artifact'. In addition to these seven divisions, there are three special grades: Silver Special, Black Curse, and Color Growth, all of which are equivalent to Purple Rare at the lowest level, and the highest upper limit is greater than Orange Epic.

(Red Legacy: Soul binding is required, and it cannot be used by others unless it dies after use, it must be a set.) /With the exception of the Red Legacy, only a small number of Red Legendary and Orange Epic equipment require Soul Binding. ）

(Silver Special: i.e. special equipment/Black Curse: Generally ominous equipment with a curse or constant negative effects/Color growth: i.e. growth equipment/These three types of equipment must be soulbound to equip and use)
