What are friend Fights in Vanguard Zero? This section under the Fight tab lets you challenge another player by sharing Room IDs so you can challenge them. Friend Fight enables to you join rooms, or you can create rooms for yourself in order for someone to take on a challenge.
When using the Friend Fight feature, you’ll get to have access to two choices if you want to challenge a friend. You can use “Search Room” or “Create Room”.
Search Room lets you input a Room ID. You can ask this from your friend if they have created their own room and you'll challenge them under the rules they have created.
When creating your own Room, you’ll then be asked if you want to have a match with a time limit or if you want to have an indefinite match time with no limit.
When you create your own room, you’ll get your Room ID at the top that you can copy and give to your friend. From here, you can prepare for your fight by choosing your deck. Once you have invited your friend and your preparation is complete, you can then challenge each other.
