Rules for poisons and nastier things

[Committed Hero]

What d20 products have rules for poisons and CBR weapons?

The last time I asked this question here, I got no responses. Nada. Zip.

While trawling for d20 Modern stuff I noticed this --

Toxicant

Then the last time you asked, I didn't see it.

POISONCRAFT, POISONCRAFT, POISONCRAFT!

http://www.rpgnow.com/product_info.php?products_id=2718&

Fantastic book, with dozens of new poisons, cooler names for existing poisons, a craft(poison) in-depth treatment, prestige classes, spells, you name it!

And you can't beat the price!

It's an Ennie Award-winner, for goodness' sake!

I'm taking a look now. It's not D20 Modern, unfortunately, but if it comes up with a way of balancing rolling a natural 20 on your skill check, I'll buy it.

Pale Designs: A Poisoner's Handbook is designed for fantasy, but it could easily be utilized for Modern with just a little bit of work, especially the variant poison rules.

True, it's not for modern; however, its rules are close enough as to be interchangeable. Not sure what you mean about "balancing rolling a natural 20"?

I designed a system to allow you to build your own poisons from scratch.

Adding more affects than a loss of hp, or an ability score. Including Mass damage reduction, speed reduction, healing reduction and some more.

Includes a varying treat injury DC as the stronger the poison the harder it would be to treat.

It is not d20modern but is easily adapted or used as is for your game.

I'll post the file here if you are interested.

A problem I have with Crafting rules for poison. In D20 Modern, you can craft nerve gas if you can make a DC 40 or so check. If you have a Craft score of +25, you can only do that on a roll of 15+. But if you roll a natural 20, there you're making nerve gas at 10th level or even earlier.

I'd rather use a system like Iron Heroes, where the strength of the poison is determined by things like feats and levels.

As for interchangeable - I wonder. How do they determine save DCs? They're lower in some d20 systems than in others.

That is one of the problems with the repair and craft system for d20m, its a one off check. Thus any one can make the hardest thing 1in20 of the time.
