Adventurer

Adventurer (冒険者 boukensha) is a job that exists in the New World. The adventurers receive and solve requests accepted by the Adventurer's Guild. The main roles of adventurers are to hunt down monsters, provide protection for important figures, and collect rare materials, etc. Usually, adventurers would not concern themselves with other state of affairs, yet there are exceptions in special cases.

Introduction
The history of adventurers started 200 years ago. After the fight between Evil Deities and Thirteen Heroes was finished, human nations suffered from social chaos and devastation. At that moment of crisis, the Adventurer Guilds were established. This gave them a new purpose for hunting down monsters and helping other people around the New World. Nowadays, there are currently so far about 3,000 adventurers working in the Re-Estize Kingdom. While so, there are also about 600 of the adventurers that are ranked Platinum and above.

Nevertheless, adventurers are anti-monster mercenaries. As the name implied, they also ventured into ruins and unexplored regions of the New World. Still, most of their work revolves around exterminating monsters. To be an adventurer, one must register at an Adventurer's Guild.

Rank and Difficulty
Adventurers are primarily classified by the rank given to them officially by Adventurer's Guild. The naming of one's rank follows by the varying metals used in the adventurer's licensed plate legally (used as identification). Moreover, a dog tag-like plate is given to all who register at an adventurer guild. Additionally, the material for one's plate is made out of depend on one's rank as an adventurer. All new adventurers recently registered into the Adventurer's Guild are given the lowest rank which is copper plate. As an adventurer's rank increases however, so do the color of their plate changes.
 * Copper - Iron - Silver - Gold - Platinum - Mythril - Orichalcum - Adamantite

The rank of an adventurer increases by passing a test of the Adventurer's Guild. Basically, the rank increases step by step, but if an adventurer achieves a major feat, it is possible to pull up his or her rank several steps at a time. Becoming a high-ranking adventurer assures better income, reward and social position and the highest ranked, the Adamantite adventurers, are treated as heroes, regardless of their nationality.

There are also difficulty levels given to monsters or quests. The higher the level an adventurer and their group becomes, the more difficult the quest are available to them. However, there is an unspoken rule among adventurers that one should never judge an opponent by their merely difficulty. This system was created, so that people don't lose their lives recklessly attempting to do dangerous missions beyond their ability.
 * F Class: 1~10 - People who are skillful at handling weapons can fight against monsters with this difficulty (ex: Normal goblins).
 * E Class: 11~20 - Monsters that can't be beaten by normal person, only by trained person. (ex: Ogres)
 * D Class: 21~30 - Needs veteran soldiers or adventures to deal with.
 * C Class: 31~40 -
 * B Class: 41~50 -
 * A Class: 51~60 - A rank that an ultra-elite warrior can manage.
 * A+ Class: 61~70 - Adventurers that use 4th tier spells are here.
 * A++ Class: 71 ~ - A rumored difficulty level that is suitable for an Adamantite adventurer which is around 90.
 * Everything that is difficulty 100 and above is considered to be above humanly possible.
 * The La-Angler Lava Lord is around 140.
 * Entoma and the other Pleiades are around 150.
 * Demiurge and Ainz (as Momon) are seen as around 200, but as their levels were too high, Evileye could not accurately judge them. Platinum Dragon Lord seems to be around this level as well.

Parties
Monsters have various special abilities depending on their type. In order to face as many kinds of monsters as possible, adventurers normally form parties of people with different skills. Low-ranking adventurers cannot work higher-level jobs, so parties are generally formed by adventurers of similar ranks.

For financial and other reasons, low-ranking adventurers tend to cluster together at certain inns. On the other hand, high-ranking adventurers cluster at others, so that makes it easy for adventurers to find compatible party members in the places where they're staying.

Social Standing
High-ranking adventurers earn incomes that match their ranks, but no matter how much an adventurer makes, they have a hard time earning people's respect. Of course, there are instances when someone receives gratitude for a job they've done, yet that seems to be more directed at the individual who performed the service rather than them as an adventurer. If regularly employed soldiers are like full-time employees, then adventurers are like temp workers.

Since adventurer power is a existential threat to rulers, adventurers are hardly even praised by their own nations. In countries where the army has the capacity to take care of monsters themselves, adventurer status is even lower. There are no adventurers in the Slane Theocracy, and the standing of adventurers in the Baharuth Empire has been falling ever since the current emperor, Jircniv came to power.

Trivia
