DESCRIPTION
This spell functions as fathom pit, except that it places a bottomless pool of acid at the bottom of the pit. The pit has a maximum depth of 100 feet. Creatures who fall into the pit take falling damage as normal (the acid counts as a yielding surface), plus 2d6 points of acid damage per round spent in contact with the acid. In addition, exposed items carried by a creature in the pit also take this damage. The walls of the pit are quite slippery and have a Climb DC of 30.
