Challenge duels

A duel is a match against a player you choose. You send the challenge and set three things:

• the stake;
• the length of the series: first to 1 up to first to 9 wins;
• the start time.

When the rival accepts, the stake is frozen on both balances until the series is over. Matches are played one after another until someone reaches the agreed number of wins.

Duels count toward the league ranking just like PvP.
