Help Frenzy

Syntax cast 'frenzy' <target>

The frenzy spell fills the target with righteous fury, greatly
increasing his or her attack skill and damaging capacity.
Unfortunately, this divine wrath is coupled with a tendency to
ignore threats to personal safety, making the character easier to
hit.  Frenzy provides immunity to the calm spell (see 'help calm'),
and may only be used on those of the caster's alignment.
