SPECIAL ABILITIES

Double Bite (Ex)

An amphisbaena worm can make a full attack without the usual –4 penalty if its bites are targeted 15 feet or more apart, whether two separate creatures or one target more than 15 feet wide.

Radioactive Bite (Ex)

A creature bitten by a mutant worm is exposed to medium radiation (see Radiation), acting as a poison on the Constitution track (DC 17 Fortitude negates). A creature swallowed by the worm is exposed to high radiation each round at the beginning of its turn, increasing the save DC to 22. A creature failing a save against this radiation exposure acquires radiation sickness, as described in the same section. This is a poison effect. The save DCs are fixed and are not based on the worm’s ability scores.

Split (Ex)

When an amphisbaena worm suffers 28 or more slashing damage from a single source, it splits into two worms. These worms each have half the remaining hit points of the original and only one mouth, losing the double bite and split ability.

Radioactive Bite (Ex)

A creature bitten by a mutant worm is exposed to medium radiation, dealing 1d4 points of Constitution drain (DC 17 Fortitude negates). A creature swallowed by the worm is exposed to high radiation each round at the beginning of its turn, dealing 2d4 points of Constitution drain (DC 22 Fortitude negates). A creature failing a save against this radiation exposure acquires radiation sickness, taking Strength damage as a secondary effect once per day thereafter. This secondary effect ends only after a character succeeds at two consecutive Fortitude saving throws to resist secondary radiation damage. If a character has Strength damage equal to his current Strength score, further damage dealt a secondary effect is instead Constitution damage. This is a poison effect. The save DCs are fixed and are not based on the worm’s ability scores.

Purple worms are giant scavengers that inhabit the deepest regions of the world, consuming any organic material that they encounter. They are notorious for swallowing their prey whole. It is not uncommon to hear of a group of adventurers vanishing down the ravenous maw of a purple worm, screaming as they disappear one by one.

Although they seek to consume living creatures, purple worms also consume vast amounts of dirt and minerals as they burrow underground.

The insides of a purple worm may contain a considerable number of gemstones and other items able to withstand the corrosive acid inside its gullet. In areas filled with radioactive isotopes, tainted effluents, and similar toxic waste, some purple worms are able to not only survive their exposure but to thrive within it, albeit horribly mutated by the effects of radiation. Their habits are otherwise identical to their ordinary kin, but they are if anything even more greatly feared.
