This magic must be cast upon a normal object-a length of vine, a stick. a pole, a rope, or a similar object. The spell causes the object to rise slightly off the ground or floor it is resting on to trip most creatures crossing it, if they fail their saving throws vs. spell. Note that only as many creatures can be tripped as are actually stepping across the enchanted object. Thus a three-foot-long piece of rope could trip only one man-sized creature. Creatures moving at a very rapid pace (running) when tripped suffer 1 point of damage and are stunned for 1d4 + 1 rounds if the surface they fall upon is very hard (if it is turf or other soft material they are merely stunned for the rest of that round). Very large creatures, such a elephants, are not at all affected by a trip. The object continues to trip all creatures passing over it including the spellcaster, for a long as the spell duration lasts. A creature aware of the object and its potential add a +4 bonus to its saving throw roll when crossing the object. The enchanted object is 80% undetectable unless a means that detects magical traps is employed or the operation of the spell is observed. This spell does not function under water.
