My guild and I have taken note and being under the influence of poison DOES lower your defense. Very much like having low stamina. Does anyone know by how much it lowers it? If nay sayers would like to try it do this : Get a group of creature that are able to hit your target 1 out of 5 hits. We used cows. Have your target surrounded. We used this tactic to train parry. Then watch the health meter. Drink or cast poison on the test target watch the damage roll in. This is great for training, but bad in a fight. It also SEEMS to come off the cap. We even tried it on someone that had well over max DCI and looked as though it was cut from the top of the cap. I argued this point once before and was booed off staged without being heard. I have since does more research but hit a wall with the formula.
