The paid arena lets the completed squad fight in interactive memory environments while preventing direct totem attacks from killing their summoners.
Carl and Donut enter after the announced price increase. Medium difficulty now costs 2,500 gold and matches the strength of their deck; Donut wants challenge difficulty for the unlock reward, but Carl selects medium for the first test.
A warning says consumable cards used inside are truly lost. The deck locks ten seconds before combat, preventing last-second edits.
Donut selects an Earth-standard 1980s shopping mall rather than a plain arena. The simulation contains physical crowds, shops, smoke, Christmas decorations, coins, and interactive people who panic, obstruct movement, and can kick Samantha.
Totem attacks cannot directly kill Carl, Donut, Mongo, or Samantha, but environmental damage remains possible. Shi Maria's fifth eye still affects Carl mentally, revealing that protection is incomplete.
A simulation chamber transformed into a crowded 1980s Christmas mall as combat timers and cards appear.
The arena exposes squad behavior safely enough to prevent direct friendly-fire deaths but not all secondary effects.
