Special Attacks

Venomous Setae (Ex)

The caterpillar’s hair-like spines deliver a severe toxin on contact.

A creature that touches, handles, or strikes the caterpillar must succeed on a DC 13 Fortitude save or suffer:

• 2d4 nonlethal damage
• 1d4 nonlethal damage per round for 1d4 rounds
• –2 penalty on attack rolls, skill checks, and ability checks due to intense pain

If the save is failed by 5 or more, the creature also suffers:

• 1 point of Strength damage
• Shaken condition for 1 minute

Special Qualities

Fragile Body (Ex)

• HP 1; any successful attack destroys the caterpillar
• Easily dispatched with a weapon, object, or spell
• However, destruction may still trigger venom if contact occurs

Clinging Spines (Ex)

• Venomous spines remain embedded after contact
• Removing them requires a DC 12 Heal check (full-round action) or adhesive
• Until removed, the victim continues to suffer ongoing nonlethal damage

Radiating Pain (Ex)

• –2 penalty on Concentration checks
• 20% spell failure chance while affected by the venom

Encounter Note

These creatures are not aggressive. They are accidental hazards rather than enemies.

• A creature brushing against foliage may trigger a DC 12 Reflex save to avoid contact
• Attacking the caterpillar is trivial - but careless attacks may still cause exposure

Lore

In the humid green wilds where growth is unchecked and life thrives in tangled abundance, the puss caterpillar is often mistaken for something benign - perhaps even comforting. It resembles a soft tuft of fur or a clump of moss caught on a branch, an illusion that has caused countless travelers, hunters, and children to reach out without hesitation. Those who do rarely make the mistake twice.

Among rural communities and frontier settlements, these creatures are whispered about in hushed tones. Not as predators, but as accidents waiting to happen. Elders warn that beauty in the wild is not always a sign of safety, and the puss caterpillar serves as a grim reminder of that truth. Its pain is remembered long after the swelling fades - a lingering lesson that even the smallest things can carry consequences far out of proportion to their size.

In some regions, particularly those touched by older and stranger magics, there are stories that the puss caterpillar is not merely an insect, but a symbol. A quiet embodiment of hidden suffering - something that looks soft, harmless, even inviting, but delivers pain the moment it is embraced. Certain folk claim these creatures are more common near places where sorrow has lingered or where the veil between life and death feels thin.

A few more superstitious traditions go so far as to associate them with minor spirits of discomfort - harmless in intent, yet insistent in their presence. They are said to “teach respect” through pain alone, never hunting, never chasing, only waiting to be touched. Whether this is merely coincidence or something more deliberate is a question best left unanswered. Those who have felt the caterpillar’s sting tend to agree on one point: it is not an encounter they forget.
