DEADLY PKILL
-------------------------------------------------------------------------------
A 'Deadly' character is one who has chosen to follow the path of the player
killer (pkill). This choice is usually made when first entering the Realms,
though you may also become deadly by requesting a level 57+ Immortal to set 
you as pkill. A deadly character may never return to the peaceful way of life.

Unless in an arena, deadly players are ONLY permitted to attack other
deadly players.

A period of grace is granted to deadly characters between their entry into
the Realms and the time when they must be prepared to defend themselves.
A pkiller does not appear on the 'who deadly' list until reaching level 5
and 18 years of age. Until this time, they may not engage in pkill activities.

Multiplay of a deadly character is forbidden, unless the character does not
appear on the 'who deadly' list due to not reaching level 5 and 18 years old.

Equipment worn by deadly players in player versus player (pvp) combat will
not scrap, but may still be damaged and require repair.

When a deadly dies in pvp combat, they become subject to a 5 minute timer
that renders them unable to attack or be attacked. This timer clears if
the character logs off. Corpses of those killed in pvp may be looted of up
to 1 item by the player who struck the killer blow.  (Only some areas qualify
as eligible for looting other players' corpses.)

Deadly characters level at a faster rate, quaff faster and inflict
greater pvp damage. However, they are also subject to an adrenaline rush 
during combat that affects their ability to recall.  They are also subject
to restrictions on supplicate while adrenalized and if trying to retrieve
a corpse.
