First, the poisons are ICly liquid. Is there a prog I can put on them so that when they're emptied in/on to a food or beverage, their effects are transfered to that item, maybe with a flag that appears on a successful wisdom check indicating that there's something off about the item, and a 'poisoned' flag for detect poison?
Second, is there a way to make the spell effects of the poison such that they're affected by anti-poison (like remove poison, or protection from poison) rather than anti-magic measures (like dispel magic or magic resistance)? I was hoping to make the poisons ICly mundane, and simply exotic, as they're from an area PCs have a pretty good chance of dying in. I suspect doing this, if possible, might be more complicated than it's worth, but I figure there's no harm in asking
And, on a similar note, is there any way to change the affect list from the actual spell effects to some kind of poison effect (presumably differentiated from "normal" poison)?
Finally, is there any way to make it so the poisons can be spread on a PC's weapon just like poisoning powder, but with a more powerful corroding effect due to the higher toxicity of the poisons?
