Golden Dart Frog Toxin

This poison is extracted from the skin of the golden dart frog, the deadliest of the many arrow frog species. As a follow-up agent, it has no delay, and eight 30-second cycles. For each cycle, make a HT-4 roll. Failure means 2d toxic damage and a heart attack (p. B429); success means only 1d toxic damage for this cycle. At 1/3 HP, the user suffers -2 DX from muscle spasms, regardless of success or failure. As a digestive agent, it has a one-minute delay, but is otherwise identical. As a contact agent, it deals 1d-2 (min 1) toxic damage and causes a horrible rash. If splashed in the eyes, treat it as a follow-up agent with a 1d second delay.

Note - It is only found in very small areas of South Carrouban, and doesn't see use outside of this - transporting live frogs across long distances would almost certainly kill them, removing them from their diet causes toxin loss, the toxin very rapidly degrades outside the living creature, and heat and humidity further degrade usability.
