Usage:
cast hold undead <target>

The spell 'hold undead' attempts to immobilize undead targets and halt
combat.  Without a specified target, the spell attempts to affect all undead
in the immediate area, although it is more likely to succeed when focused on
a single undead.  The hold is immediately broken if the undead is attacked.
The undead can also sometimes break the hold if the cleric leaves the room or
is otherwise distracted.

Hold undead can be used to bypass aggressive undead, hold multiple undead
in place for area attacks such as certain mage and druid spells, or
immobilizing a single target for a backstab, especially if the undead moves
quickly or flees when injured.
