Mobarmy Battles

A team-based PvE minigame plugin for Paper 1.21.x. Two teams farm mobs in separate worlds, configure attack waves, then battle each other's armies in a copied arena.

How It Works

Lobby — Players join Team A or Team B via the Team Selection GUI (right-click the Iron Sword).

Farming Phase — Each team is teleported to a unique survival world. Kill mobs to collect them for your army. A boss bar counts down the remaining time.

Configuration Phase — Players are frozen in place and assign their collected mobs across three attack waves using a GUI. Click Ready when done.

Battle Phase — Both teams are teleported to identical arena copies. Mobs spawn wave-by-wave against the opposing team. The last team standing wins.

Random block drops (every block drops a randomized item

Team backpack (shared chest item per team)
