Magic Item: Staircase Carpet

I saw this picture on Jason Blalock's G+ feed.





So naturally, I have to stat it up.


For Swords & Wizardry / Basic Fantasy Role-Playing / Labyrinth Lord / D&D 5e:

Portable Staircase. Once per day, the owner may unroll this carpet and use it as a real staircase down. It can create a temporary staircase down through up to 30' of material. The staircase will reach up to a further 10' down to touch the floor. If no open space exists within 30' of the surface it is placed upon, the carpet does not function. It can> open into open air, however. Once rolled back up, the staircase disappears. Anything on the staircase is either dropped back down to the level below or to the level above (50% chance of each) and is unharmed by the process. The staircase lasts until the rug is rolled up, after which the carpet must remain unused for 24 hours to recharge. The carpet can be rolled up from above or below; this takes 1 round. 6' x 3', Weighs 5#.

For GURPS:

Portable Staircase. Allows the user to create a temporary staircase down. Treat this as Create Door, but it only functions vertically down, penetrates up to 10 yards of material. The staircase will extend up to 4 yards past this point to touch the floor. Functions once per day. Once rolled back up, the staircase disappears. Anything on the staircase is either dropped back down to the level below or to the level above (50% chance of each) and is unharmed by the process. The staircase lasts until the rug is rolled up, after which the carpet must remain unused for 24 hours to recharge. The carpet can be rolled up from about or below; this takes 10 seconds. 6' x 3', Weighs 5#
