This script command allows you to easily poison your weapons in one click using a macro. This differs from simpler macros in that you don't have to specify the location of your poisons in your bags for the script to work. The script searches your bags for the desired poison and uses it on the desired weapon. This is handy for people who carry more than one stack of the same type of poison. It also takes into account the rank of poisons and will use a more powerful ranked poison over a lower ranked one.
