Agile Strikes (Ex) A wespenspinne adds its Dexterity modifier to damage from its natural weapons rather than its Strength modifier.
Immobilization Poison (Ex) Bite—injury; save Fort DC 18; frequency 1/round for 8 rounds; effect 1d6 Dex—for every 2 Dex damage dealt, the victim's base speed decreases 5 ft.; cure 2 consecutive saves. The save DC is Constitution-based.
Wespenspinne Implantation (Ex) Sting—injury; save Fort DC 18; onset 1 day, frequency 1/day; effect 1d6 damage to random ability and 2d6 hp; cure 2 consecutive saves. When a wespenspinne implantation's victim takes damage from the disease, a full-grown wespenspinne emerges from the wound; it uses the same stats, but its sting does not inflict disease. A victim killed by the disease (either through loss of hit points or the reduction of any ability score to 0) releases 2d4 wespenspinne, 1d2 of which can implant opponents with its sting attack. The save DC is Constitution-based.
No creature has claimed responsibility for the creation of the wespenspinne, leaving scholars to speculate that a spider-killing wasp implanted its eggs in a spider while in an area of wild magic. The resulting creature gained a baleful intelligence and seeks to infest others with its progeny. A wespenspinne possesses both a spider's poisonous bite and the spider-killing wasp's ovipositor, a combination it employs to implant wespenspinne larvae into new hosts. Since the larvae need a living host, a wespenspinne breaks off its attack after it has a chance to sting multiple victims (or the same victim multiple times).
In an inexplicable gestation cycle, new wespenspinne erupt from their host one at a time on a daily basis until the victim succumbs to all the damage inflicted by the exiting creatures or manages to fight off the larval infestation. Each newly birthed wespenspinne bursts from a random location on the victim's body and may immediately attack its former host in its confusion. Once the new wespenspinne realizes the victim hosts a new queen, it discontinues the attack and follows the victim. While the victim still suffers from the implantation, the emerged wespenspinne "protect" him, providing the victim with unexpected allies against opponents, but also preventing others from touching him in an attempt to cure the infestation. The body of a victim that succumbs to the disease bursts open, releasing several wespenspinne, including at least one new queen who starts the process again.
