This trap defends the home of a master illusionist.  It has no moving parts to wear out, it is almost no inconvenience for the wizard, his family, or his servants.  However, it can dramatically slow down invaders who do not know the trick.

The trap is a simple pit, and can have spikes in the bottom if the GM wants to make is a little more deadly.  There is a permanent illusion of a mosaic over the pit, and it appears to the unwary like the picture on the left.  (Note that this should completely fill the hallway, so one can't get around it.)  However, the actual  floor, if the illusion were removed, looks like the image on the right.

Crossing the trap at normal speed requires an acrobatics roll of DC 30, with the following modifiers:

Have been told and shown the correct places to step:  +15
Have successfully crossed it before: +1 for each time, up to +10
Take 2 rounds to cross, feeling your way:  +5 (can take a 10)
Take 5 rounds to cross, +5 (can take a 20)
Slow to half speed: +3
Running (double speed): -5

The residents of the house are rolling at +25, and can take a 10 normally, so it is not at all a hindrance to them.  However, someone who is, say, charging in with a weapon drawn will almost certainly fall in.  If you put this in a hallway just after a left-hand turn, then running diagonally across the mosaic will seem normal, and pursuers won't see that the residents are watching their step as they cross.
