What is Player vs Player?
Player vs Player (or PvP) is a combat feature where players compete against each other instead of against creatures. Similar to dueling, Player vs Player dueling is a much more in depth method of matching your skills against other players.
Where can I play PvP?
The Player vs Player Arena is located in Unicorn way, inside the current dueling arena.
Just look for Diego, he's standing next to the entrance. Inside you will find two pedestals with Scrolls on top.
The Scroll on the right is for Practice Dueling and all players can participate in this.
The Scroll on the left is for Ranked Dueling. These are duels that can earn you Arena Tickets and are only available to Members or with Crowns on a Pay-as-You-Go plan.
