Characters may duel in the arena regardless of being deadly or not, with
no penalty. You cannot die in the arena and upon reaching 1 hitpoint you
are transported out and defeated. Rules for the arena are agreed upon
by the combatants and must be followed by both parties.
Note that deadlies may attack peacefuls inside the arena, and that
equipment will not scrap while in the arena.
Also, the arena is governed by the rules of decency. It is for sport,
not for spite, so no equipment may be stolen from players in the arena.
Disarmed weapons are to be returned to their owner.
