Combining Poisons

[James McMurray]

IS it possible to apply multiple poisons to a single weapon? If so, what are the rules on it. Do the reduce each others' efficiency, interact in any way, etc.?

Thanks!

I do not think that there are any core rules dealing with this. However, I don't think that stacking poisons is particularly overpowering. The saves are pretty low for a mid to high level character. And the price of poisons is too high for low level character. The DC's do not stack, instead, the opponent will make a separate save against each poison. However, as a DM, I would probably tell the player that poisons could interact. The interaction would then be determined by a secret roll.

I have told the NPC that poisons might interact, and that he won't be allowed to watch my secret roll. Now then, any ideas for interaction effects?

I would say that interaction can take one of four forms. The poisons functioning independently as described above. The poison can cancel each other out. The poisons can interact to boost the DC of one poison, determine again by roll, and second poison would have no effect. I would say that each case has a 25% chance. However, if you think that this would be unbalancing, you can change the percentages as you see fit.
