ArenaPlugin
About
A configurable arena system for Minecraft *.21+. Players use a selection wand to define arenas with Pos1/Pos2, then configure each arena via an inventory GUI: choose a trail block that generates behind players as they walk, manage potion effects applied while inside, and toggle exit-blocking to prevent players from leaving. On death, all trail blocks restore after 10 seconds. All data persists in ******.yml.
