Area of effect: One or more stairs (this will be up to you).
Arm time (time to arm this trap): 6 turns (30 seconds).
Audible effects: There will be a shifting sound like a smooth grating of floor-boards. The more stairs that collapse, the louder it will be. There will be a sound, like a board being dropped on a flat surface as the stairs set in place. Again, the more stairs that set into place, the louder it will be.
Avoidance-roll:

When this trap is triggered, all within the "Area of Effect" must make a successful "Coordination" check (your current coordination will be the % chance to succeed).

Successful:

Victim will remain in standing position, sliding downward. Each turn the victim slides, a successful avoidance-roll vs. "Coordination" must be rolled, or he or she will fall. While falling in this manner, the victim will be able to attempt to grab onto something one time per turn (no extra actions can be taken per turn if the victim has the Divine Favor, "Spirit of Battle", or, "Spirit of War".

Unsuccessful:

Victim will fall, helplessly sliding and tumbling downward until reaching the bottom of the stairs.
