I have a few questions:

1. The alchemy perk "Concentrated Poisons" suggests that this time poisons will not be used up after the first attack. Does anyone know how many attacks a poison lasts for?

2. Any examples of in game purchasable poisons known yet?

3. Any examples of in game poison effects known yet?

4. I remember hearing that you could poison a weapon from the blood of a spider, true? Anyone know what the poison does?

5. Anything else interesting about poisons you want to share (other than plot related stuff plz)

I can only comment on the spider poison, I have seen that it is an attainable item from the corpse of giant spiders, I however have no idea on the effect.

I know that with a perk you can put poison into a person's pocket to harm or kill them.
