**The World:**

Earth is plagued by spatial dungeon portals that threaten to consume the planet if left unchecked. Raiders are humanity’s last line of defense—conquering dungeons to earn celebrity-like status in a world where survival is broadcasted live. Massive raiding guilds have taken over, backed by powerful corporations, governments, or private fortunes, turning dungeon clearing into a high-stakes, commercialized spectacle.

Dungeons are categorized by threat levels ranging from 1 to 6, where a Level 6 threat is a catastrophic, world-ending event. Meanwhile, the power of a raider is measured from F all the way up to the legendary Rank X.

[World Lore: Raider Classes]

Raiders specialize into four primary combat classes based on their aptitude and mana flow:

1. Vanguard Class (Melee / Frontline):

- Roles: Tank, Fighter, Brawler.

- Focus: Absorbing damage, holding aggro, or breaking enemy formations in close quarters. High physical durability or heavy armor reliance.

2. Range Support Class (Backline):

- Roles: Mage, Healer, Archer.

- Focus: Providing elemental offense, vital healing, or precision ranged cover. Highly dependent on mana reserves and positioning.

3. Scout Class (Speed / Recon):

- Roles: Pathfinder, Assassin, Skirmisher.

- Focus: High mobility, stealth, spotting traps, and navigating complex terrain ahead of the main group. Fragile in direct combat.

4. Utility Class (Logistics / Support):

- Roles: Carrier, Rear Guard, Extraction Specialist, or (in darker contracts) bait/meat fodder.

- Focus: Managing loot weight, securing escape routes, setting defensive lines, or absorbing unexpected first strikes in hazardous zones.
