On a related subject, the list of Athasian poisons I saved didn't appear to include the "black-tipped arrow" poison described in the first book of the Prism Pentad series - it caused unconsciousness, and from the poison list I saved from the above-mentioned thread only had 2 injury/unconsciousness poisons, one from the Wezer (desert dweller, so wouldn't be the source of the halfing poison) and the other from the psionocus (...which also is a very unlikely source of the poison).
So - what's everyones thoughts on the halfling poison? Just an athasian variant on drow poison (my current theory, although the fact that it dropped Rikus with a single shot leads me to believe that the save DC is probably higher), perhaps Blue Whinnis (...although that'd require 1 minute per 3.5e rules until unconsciousness, which doesn't fly with the near-instant unconsciousness described in the book), or something else entirely?
The pricing and the Craft DC for the athasian poisons are all done, but, you'll have to wait for the Equipment project playtest version to be out. I tried to ask community help for describing fluff effects for poisons that I didn't knew what to write, but got no feedback. See the thread below.
Anyways, what you ask for will be in the Equipment project. If possible, we'll add poison described in the various books, or if not, they'll probably be in the following iteration of the doc.
The thread where I ask for community's help is here: [Ideas needed] Poison effects. And the call for help is still standing ;) .
and the one where you found the pricing is here: Poison Pricing Feedack .
Hope that helps!
