Wands are the simplest form of enchanted items, items that store magic inside
them for later use. While these are relatively simple compared to artifacts
crafted by gods or the like, they are not simple at all. Nasty consequences
can befall those who attempt to use items such as wands with no knowledge of
the type of magic that allows wands to hold and discharge spells.  While some
say that using wands is as simple as pointing a finger, those who are not
familiar with wands and attempt to use them can bring about disastrous
results. Carrying one wand is always safe, when carrying more wands the skill
zapping will help pointing out when you are pushing your luck too much.
Everyone knows the first question any apprentice asks when being taught this
skill is: 'Which end do I point again?'
