Here is what i found on the storebought poisens rogues can use at lvl 11. Place them in your activate slot in your inventory. Then drag the icon for them to your quickbar. Clicking on the button on your quickbar activates a 12hr buff of the poisen type you equipped. The two storebought poisens I had the skill to try would not stack.

Abrasive Goo - less than 10cp. Resisted by the smallest grey mobs in freeport.

Acidic Goo - Just over 30cp. Proc's a 20hp DD. Worked on blue and green mobs (at lvl 11) that were handy to test on in freeport. Occasionally double proc'd for 20hp and 13hp from one attack (happened twice on a blue and once on a green).

I'll post more on the crafted poisens when I get a chance to test them out.

No, you apply it to your weapons. It shows up as a buff. Each attack it has a chance of doing 20dd (for acidic goo) with a chance of doing an additional 13dd.
