Syntax:
envenom [object] with [liquid container]
This command causes the player to attempt to apply a liquid over an item. It may be obvious that poisons can be applied to weapons, but a poison can be also be applied to a food to make the food poisonous. If the quantity of the liquid is much larger than the size of the item, the item is dipped in the liquid. Otherwise the liquid is applied over the item. The same command will allow liquids to be applied over most items.
Example:
envenom blade with black vial
