Pit (Ex) A pitshaft is 100 ft deep. A pitshaft simply moves into its foes space as a move action, causing all creatures that occupy its space to fall into the pit (Ref DC 20 negates). Creatures that save successfully move to an adjacent square. Creatures falling in the pit take 10d6 falling damage. The save DC is Dex-based.

Vulnerability to Extradimensional Space (Ex) Any extradimensional space brought within a creeping pit causes it to invert for 1 hour. Inverted creeping pits suck all objects and creatures within 10 ft to the Astral plane (Ref DC 24 negates). After 1 hour, the creeping pit is destroyed. Additionally, a gate spell has the same effect on a creeping pit if it is opened from within the hole. The save DC is Dex-based.

Skills Creeping pits have a +8 bonus on Move Silently checks.

Strategy and Tactics A pitshaft prefers to hide completely within a wall or just inches under the surface of a floor until it detects nearby creatures with its tremorsense. When it does so, it emerges from hiding behind a large group, moving silently, until it successfully traps a creature in its pit. It then remains motionless (unless it is attacked) until no creatures are within its tremorsense. If attacked, its dashes at the enemies, trapping as many creatures as it can within its pit before returning to its hiding place.

Ecology Pitshafts are created when a bag of devouring is placed within a portable hole. This opens a rift to the Astral plane for 1 hour, after which a pitshaft is created. Pitshafts co-exist on the Material plane and the Astral plane. Objects and creatures that stay in the pit have a 25% chance per hour of transporting to the Astral plane. Objects and creatures thus transported provide nourishment for the pitshaft.

Environment Any underground

Typical Physical Characteristics A pitshaft is a 10 ft square by 100 ft deep pit composed of the same material as that of the surrounding area. The hole of a pitshaft is actually an extradimensional space that remains open; this cannot provide egress through the floor on which it travels.

Alignment Always neutral

Typical Treasure Half standard
