Only Wizards learn power words.

<code>
Power words are the most potent of all spells, transforming long periods of
tedious memorization into a single, sublime burst of arcane majesty.  They can
only be learned by the most dedicated spellcasters, but they have truly
devastating effects. No saves are allowed against power words of any kind, nor
is there a way to resist them.

PREPARING

A power word must be memorized before you will be able to use it.  This is done
by casting the spell as normal.  This can be a long and tedious process in many
cases.  When it reaches 100%, you will have memorized it.

All power words you have memorized will show up in your statistics window.  You
can't have more than one of any given power word memorized simultaneously. i.e.
You may have a 'KILL' and a 'BLIND' memorized, but not two of 'BLIND'.

USING

Power words may only be used in combat, and some have additional restrictions
outlined under their individual descriptions.  You use a memorized power word
by typing, not saying, it.  e.x.:

> limited invulnerability
NOT
> 'limited invulnerability'

Using aliases is recommended for the longer ones.  Once you use the word in
combat, your memory will be cleared of that word, and you will need to memorize
it again.
