This creature looks like a puffy and bloated human-sized whitish-yellow maggot with purplish veins pulsating under its fleshy form. A vaguely humanoid head sits atop its body and its facial features are twisted and distraught as if the creature was in a constant state of pain. A pair of large, downward-curving horns juts from its head, just above its sunken eyes. Its mouth is lined with filthy and sharpened fangs.
Speed 20 ft.
Abyssal larvae use digestive juices to break down their foods. This acid often remains in their mouths and is transferred to a victim bitten by a larva. Any melee bite attack deals acid damage.
Once per day, an abyssal larva can regurgitate and fire a stream of maggots at a single opponent within 10 feet. This requires the abyssal larva to succeed on a ranged touch attack. If the attack succeeds, the opponent is sickened for 1d2 rounds. A successful DC 10 Reflex save reduces the sickened condition to 1 round. The save DC is Strength-based.
The mind of an abyssal larva is a warped and tangled mass of chaos. As a result, abyssal larvae are immune to all mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects). A creature attempting to contact an abyssal larva with a mind-affecting spell or effect (including psionics) must succeed on a DC 14 Will save or be affected as by a confusion spell for 1 minute. The save DC is Constitution-based and includes a +4 racial bonus.
