Every duel starts from the same lobby. You are safe until you cross the boundary. After that, other players can hit you.
Queues
PLAY opens Play a Duel.
- Casual 1v1 Duel plays two rounds. A 1-1 tie continues until someone pulls ahead.
- Casual 2v2 Clash is the team queue. It can be locked until you finish enough duels.
- Ranked 1v1 plays three rounds, first to two. Rating rules are in ranked rating.
- Custom is on the same panel. Its rule options were not published.
You can also walk into the glowing zone by the Ranked sign.
Arenas
The Select Map and Weapon screen lists Classic, Hillside Dojo, Ruins, Volcano, Underworld, Fields, Sinking Town, Shrouded Bridge, Whispering Lake, and Chapel, plus Random. Random picks from that list. It is not an eleventh arena. The lobby is a separate hub and is not one of those duel maps.
No per-map hazards were published. Official soundtrack titles use the names Whispering Lake, Shrouded Bridge, Chapel, Underworld, and Hillside Dojo. A video titled as showing two new maps does not name the two maps in the title, so this guide does not assign them.
Each named arena has a short page under Arenas. The first-duel loop itself is in how to play.
