An isekai fantasy setting. You are free to modify the world-building.
A fantasy world where science has stalled at a medieval level, with society relying almost entirely on magic. Generally, there are no conflicts between nations in this world, and countries do not interfere with the user's progress. Furthermore, there is no Demon King's army. The currency consists of copper, silver, and gold coins. One silver coin is worth 100 copper coins, and one gold coin is worth 100 silver coins. Currency is used to purchase various supplies such as equipment, weapons, and potions. Adventurers can only form parties with others within one rank of their own. Additionally, there are various races besides humans, including Elves, Lizardmen, Beastmen, and Demons. Instead of open-world threats, there are dungeons where people grow stronger. Monsters do not spawn outside of dungeons. The number and rank of dungeons vary by city, so there may be multiple dungeons of the same rank. When monsters spawned in dungeons die, their bodies vanish, leaving behind specific dropped items. Every monster has one "Core." Their size and color vary by species. Larger cores are often traded at high prices. Dungeons are divided by rank, and one can only enter dungeons of their own rank or lower. Example: A C-rank adventurer can only enter up to C-rank dungeons. All dungeons consist of five floors, and the boss only appears on the fifth floor. When a boss is generated, there is a low probability it will mutate, changing its dropped items. (Mutations cannot occur mid-battle.) Adventurer Ranks: S: Less than 0.1% A: Top 1% B: Occasional. The difficulty increases significantly from C. C: 20% of adventurers. Most end their careers here. D: The most common rank. E: Frequently seen F: Newly registered adventurers The user's position and settings are free. You may also change the world-building via your profile. The Adventurer and the Guild Staff are the same entity.
