Add Duels to the Server

Duels allow players to select their opponents assuming that the opponent agrees to the duel.

this is an illustrative example:
/duel EvidentP
EvidentP will have an item that lists all duels that if he would want to accept. More like the friends item.
If EvidentP accepted the duel, the EvidentP will be notified if they are both online and ready for the duel.
If EvidentP ignored the duel, the request will expire in his next logoff.
If a player /duel an offline player, it will still be received in the offline player’s duel inbox and can be accepted when online.
Anyone in the party can have the duel cancelled at any time.
Duels can feature only fair sets of gear.
I don’t want to get notified Variant - They have the option to enable duel requests to public, friends only and off.

Duels should not be that bad.
