B2. Large Monster Holding. There's a Rusty Grate Pit (Hazard 6) with a Stealth DC 0.
Is that "Stealh DC 0" a typo?
I'm looking over the Building Hazards rules, and all of its stats seem to align with a Hazard 6 Low challenge, about the middle point of the range, so it would seem that a DC 20 would have been what would be expected.
I'm not saying I want a player to fall into the pit...but I really want a player to fall into the pit. :)
