Meeting with a Rust Monster

Intro

 The Dwarf blacksmith Skarfar was digging a new well on his estate when a sinkhole opened up in his digging area. The sinkhole revealed an underground cavern with possible side chambers. Being an ex-adventurer Skarfar grabbed his sword shield and armor and went down into the sinkhole to explore. He discovered it was occupied by at least one rust monster. He fled the scene safely and the rust monster did not immediately pursue him. But, his trouble only started. Two of the rust monsters burrowed into his basement. He battled the rust monsters there and died heroically trying to save his family. The PCs encounter the family when they approach them desperately seeking help to eliminate the new denizens of their basement.

Warrens

1. Entrance to the Rust Monster Warren

The entrance is treacherous terrain because some of Skarfar’s digging and well equipment fell into the sinkhole and are occupying the entrance space. Further complicating the problem is a wall of rock and debris that must be cleared away for the PCs to traverse further into the warren. The Rust Monsters can easily climb around the rock wall. One hour minimum to dig around rock wall. The family wants to PCs to eliminate the creatures in the basement and check the warrens for more creatures. The only light into the sinkhole is from the sky above. PCs must bring their own light into the warren.

2. Puzzle Room or Role-playing Challenge
The Cavern is pitch black and the floor is flooded in water 5’ high. A pool of water has settled here. PCs must cross it and dig their way into the next area. Water is very cold. Chance of hypothermia. It will take the PCs and hour to dig around the rock debris. Again, rust monsters can climb over it easily. They can also fight in the water easily. Chance of encountering a rust monster 25% per 15 minutes. 1 in 6 chance that water will suddenly flow into the chamber and fill the chamber above the PCs heads. Characters smaller than 5’ will have a certain immediate problem if they enter the chamber.

3. Trick or Setback
Once the PCs enter this area the entrance from area 2 collapses and water stars to fill up the chamber. To top it off the way to area 3 is also blocked off by a rock pile and the PCs will need to dig through it to get to area 4. It will take an hour of digging to open up the way to area 4. To back out of area three back to area 2 will take 24 hours.

4. Battle with a Rust Monster Lord

Unless the PCs already encounter three rust monsters from any random encounters there will be three of them and a rust monster lord in the chamber.

5. The Reward

In a corner of the chamber is a sack with 5 sweet water potions and 3d6 gems worth up to 1800 gp. A small creek flows out of this chamber and the PCs can follow it out if they crawl. It comes out 500' east of the Skarfar Esatate. When the PCs return to the Estate, the widow offers the PCs the Estate for 250,000 gp or 75% of the PCs wealth -- whichever is higher. She plans to sell the estate and move back to her clan with her children. She wants to leave in a hurry. The rust monsters destroyed every metal object in the basement.
