Hazardous Ruins are ruins from the Age of Darkness dotted throughout the land, populated with hostile enemies that have taken residence in the dangerous environments. They offer rare Treasure Chests, loot, materials, and items for tough explorers to plunder, but are generally closed off to the public until given special clearance. The Civil Corps is responsible for investigating and allowing access to Hazardous Ruins.

Introduction Edit

Every ruin has multiple levels, and each level spans across multiple floors. Each level entered costs a set amount of time to enter, meaning that time inside the ruins freezes and more time is not consumed while within the level or when advancing to the next floor.

Most floors must be cleared of all enemies to advance, though some floors simply require navigating through obstacles to reach the next floor. Treasure chests and/or smashable Wooden Crates can be found on most floors.

The player has a set amount of attempts, or lives, to complete a level, though the player also has the option to quit at any time in the middle of a level to return to the overworld.

Sewage Plant Edit

The toxic Sewage Plant ruins are located past in the northeast inner city of Portia, gated off within the Collapsed Wasteland. To enter the Sewage Plant, the player needs to prove their strength by sparring with a Civil Corps member in Mission: Hazardous Ruins and surviving until the timer runs out.

This Hazardous Ruin features many toxic enemies, noxious gas jets, and green, acidic water that causes damage for every second of contact.

Loot commonly dropped by monsters includes Copper Wire, Old Parts, Tempering Liquid, Venom, Teeth, Copper Bar, and Gols.

Chests offer Blood Stones and rare technological materials such as Small Engines, Lubricant, Data Discs, Small Silicon Chips, Springs, Valves, and Simple Circuits.

Killing the Boss on each level for the first time will reward you with a one-time loot item instead of the middle item shown for clearing the Level. For the 1st Level's Boss, you get one Casual Clothes jacket instead of a Small Engine. For the 2nd Level's Boss, you get the Enhanced Iron Sword Recipe instead of 2 Blood Stones. For the 3rd Level's Boss, you get a Ruin Driver's Hat instead of 1 Small Silicon Chip. For the 4th Level's Boss, you get a Lion's Claw weapon instead of 2 Data Discs. Of those one-time drops, Lion's Claws is the only unique item that cannot be obtained elsewhere.
