Abilities

Dicing Scythes

Trigger A creature steps in the 15-foot-by-25-foot area where the branching hallways connect


Effect The trap uses Scythe Shuffle; each blade makes a scythe Strike against each creature in its region, then it uses Scythe Shuffle again. The trap then rolls for initiative.

Scythe Shuffle

The blades travel erratically throughout the hallway's branches, out of sight under the floors or behind the walls. For each blade, roll 1d4 to determine the region in which it next makes scythe Strikes. A creature can to learn clues about blades in the region they're currently occupying. On a success, the creature knows how many blades are currently in its region.

1. Main intersection (the 15-foot-by-25-foot area where the hallways connect, as marked on area E20 )

2. Nor

Disable DC 26 thievery (expert) to disable each blade, or utter the magical passphrase (which only Chafkhem knows) to deactivate the trap for 10 minutes

Six long blades, hidden in grooves in the walls and floor, zigzag through different parts of this hallway when any pressure plate in the hallway intersection is depressed; there are so many plates it's impossible to avoid them when moving through the room. The blades retreat into the floor and move through the hidden grooves before swinging out from the wall again in a different location.
