The make of your weapon adds to accuracy as well as damage. For a full list of these bonuses, please see Item Make Bonuses. For example:
With the right concoction of herbs and ingredients, you can make a nasty poison and apply it to your weapon. Weapon poison lasts for 1 hit on a weapon, and depending on its virility, can do serious damage to a non-immune target.
Poison can only be applied to physical weapons, and has no duration for effectiveness. You can put poison on a blade and sheathe it for a week and still have your poison. Poison only gets removed by wiping it off, or contact with a target. A target must make a fortitude check to try to resist the poison.
Attacking a single target with multiple poisons does not stack. Instead, the strongest poison replaces the previous poison. So if you hit a target poisoned with WP+ and your weapon has WP++ on it, your poison takes effect, removing the WP+.
