Syntax: cast disguise (<target>)
With this spell, you can change your outward appearance, disguising yourself
to avoid monsters that you have fled. If the monster is not affected by
true sight, it will not be able to track you down to seek its revenge. Once
disguised, those not affected by true sight will see a disguised version of
you in the room.
Invisibility and disguise work similarly in that both protect you from being
tracked down by vengeful monsters. However, once a battle has begun, the
invisibility affect dissolves, whereas disguise does not. Monsters can
still see disguised players; they cannot, however, track them down without
true sight.
