Ooh, you really aren't supposed to be in The Rusted Vault!
Immediate room contents are listed. Contents in parentheses require further investigation to discover.
Roll 1d6 when the group enter a new area, hesitate, or make a lot of noise. On a 1, they have a random encounter. On a 2, they get a sign that one is nearby.
Random Encounters
1 - The Rusty Man: STR 10, DEX 10, WIL 15, 14hp. A faceless figure, glowing bright orange, with long claw-like fingers. Rusts one item (of any material) unless the wielder passes a DEX Save. Attacks using non-living material do not harm him, and any material used against him crumbles to rust. Can pass through the solid surfaces of the vault like a fish through water.
2 - Mechanical Mouse: A clockwork mouse that wheels its way through the corridors without a care in the world.
3 - Desiccated Ape: STR 6, DEX 6, WIL 4, 3hp. A feeble, dried out husk of an ape that can barely crawl and whimper. Anyone getting close enough will be subject to his bite (1d6). When this causes Critical Damage, the victim withers to a desiccated husk themselves.
4 - Skeletal Frame: An immobile metal frame, loosely humanoid in shape. It does not move, but sways and creeks. Will move away incredibly fast when no one is looking.
5 - Heat Signature: The unmistakable feeling of someone right next to you. Definite warmth against the cold air. Maybe some quiet breathing, but it's gone before you get too long to think about it.
6 - Magic Bullets: A pile of lead shot from a musket. The pile rolls and moves together with some intelligence. Has no motivation other than to get under people's feet at unfortunate moments, forcing a DEX Save to stay upright.
Entrances/Exits
The Long Stair: The only way in. No idea how you managed to find it, but it leads straight to an open door into room 1.
Structure: Unless noted, rooms are metal-lined and doors are the heavy iron type. There are no lights, temperature is cool, and there is a lingering smell of rust and damp.
