Normally, an arrow or bolt doesn't do a lot more or less damage when pulled
out, or left in, the wound it has made. However, if the head of it was treated
with a magical substance, such as a potion, leaving it in the wound could be
disastrous. Not only would the potion continue to inflict damage, but other
effects from the magical fluid entering the victim's bloodstream could also
ravage this body.
Syntax: use make arrow of torture at <potion> and <arrow/bolt>
Using high-quality potions is essential for this skill.
