Duels

Duels are authorized Player vs. Player fights that take place even in safe areas and will not change a player icon from green to orange or red by killing the opponent.

At the beginning of the duel player will have 60 second to prepare for the duel after the 60 second the duel will start.

Procedure
To make a duel a player must send a request to another, the second player must accept and may decide then which type of duel it will be.

After a duel is concluded, a window that indicates the winner will appear between the participants if they are within 10 meters of each other. If the participants are farther apart at the end of a duel then two windows will appear near both the winner and loser.

Types of Duel
The types of duel are:
 * Normal Mode: Rarely used in SAO, since it will only stop when a player&amp;apos;s HP reaches 0, and that will mean permanent death for the loser. This is the one used for Sleep PK.
 * First Strike Mode: This is the most common, the winner is decided by whoever lands the first clean hit or whittle the opponent&amp;apos;s HP to half.
 * Time-Limit Mode: The winner is determined by whoever has the most HP within the designated time-limit. (unconfirmed)
