Home > Bestiary > Vermin > Antlion Family >

A giant carnivorous insect that lives in the caves, digging deep pits that serve both of as nests and traps for its prey. Its carefully disguised snares are almost indistinguishable from ordinary sand, and the softness of the sands within means that once trapped, returning to the surface is all but impossible. Often the last sound victims hear is the clack-clacking of the cave antlion’s jaw as it gleefully approaches its soon-to-be-meal.

Sandblast (Su)

A cave antlion can stir up the sand around it to blast sand at its enemies within a 30-ft.-radius. Creatures within the area of effect must make a Fortitude save (DC 15) or be inflicted with Blind status for 1d4 rounds. Blue mages may learn this ability as a 2nd level spell (Knowledge: Arcana DC 19).

Sandpearl (Ex)

Sand Pearl or Desert Light acts as a cure to the illness known as the Desert Fever or any common disease. The sand pearl generally fetches for 1,000 gil each.

Sandpit (Su)

A cave antlion can cause a hole to engulf a single target within 30 ft. The target must make a Reflex save (DC 18) or be inflicted with Immobilize status for 1d4 rounds. Blue mages may learn this ability as a 2nd level spell (Knowledge: Arcana DC 19).

Sand Trap (Ex)

A cave antlion can create a 60-foot-diameter, 20-foot-deep pit in any sand or soft earth surface. Creating a sand trap takes 1 hour. A DC 15 Perception check allows a creature to realize such a depression in the sand is in fact a trap. Any creature that steps into the trap slides to the center if it fails a DC 14 Reflex save—such victims take no damage, but they do fall prone. A giant ant lion can make an attack of opportunity against any creature that falls to the bottom of its sand trap. These creatures can move across sand traps at their normal speed and are immune to the trap’s effects. Other creatures can navigate the trap’s walls with a DC 20 Climb check.

Venom Spray (Ex)

An cave antlion can breathe out a spray of venom in a 30-ft.-cone. Creatures within the area of effect take 4d6 points of non-elemental damage and be inflicted with Poison status for 1d6 rounds. They must make a Fortitude save (DC 19) for half and negating the status effect.
