NPColiseumPlugin

NPColiseumPlugin

A wave-based mob arena / colosseum event, fully built in-game — no config files to hand-edit.

Drop your players into a wave-based arena: custom mobs with their own stats, loot and quirks, pre-built kits, a friendly-fire-aware lives system, a live sidebar scoreboard and a persistent leaderboard. Every bit of it — mobs, kits, arenas, waves — is authored entirely through in-game GUI editors, with real inventory slots for placing items straight where they go.

Requires: NorrionProjectCorePlugin Optional: WorldGuard — ties an arena to a region and lets you edit every one of its flags in-game.

Custom mob editor

• Full stat sheet per mob (health, damage, speed, armor, knockback, and more)
• Equipment with per-piece drop chances, extra guaranteed/chance-based drops, and a toggle for whether vanilla loot still rolls.
• Potion effects, a configurable kill-point value, and an optional XP drop override.
• Entity-specific options where they exist: Creeper charge/radius/fuse, Ghast fireball explosion power, Wither invulnerability ticks, Slime/Phantom size, and cosmetic variants (Sheep/Wolf/Cat/Shulker color, Parrot/Fox/Rabbit/Panda/Llama variant).
• Mounts — have one custom mob ride another, nested as deep as you want.
• /npcoliseum admin spawnmob <id> to drop a fully-built mob at your feet for a quick test, no arena required.

Kit editor

• Build a kit's entire loadout — main inventory, armor, off-hand
• A one-click "copy my current inventory" shortcut for setting a kit up from scratch.
• Potion effects that apply the instant the match actually starts.
• A custom armor trim pattern per kit, paired automatically with each team's own color.
• A custom icon per kit.

Arena editor

• Identity: team count/size limits, lives (shared per team or per player), friendly fire mode, an availability schedule (always open / closed / open on a timer), spectator toggle.
• A lobby spawn, an optional WorldGuard region with a full in-game flag editor, and as many named spawn points as you want (global, or reserved per team).
• Wave builder: each wave fires one or more actions (spawn N copies of a mob at a location, broadcast a message) and either waits a fixed delay or waits until every mob it spawned is dead before moving on — optionally with a boss bar totaling the combined HP of everything it spawned, live-updating as it gets cleared.
• Pick which of your kits are available for this arena, with a one-click preview of a kit's full contents before enabling it.

Playing a match

• /npcoliseum join <arena> drops you in the lobby; pick a team (or stay a spectator) and your kit right there.
• A countdown with on-screen titles and sound, players frozen in place until go.
• Points for every kill, a live sidebar scoreboard (current wave, points, top 5, team totals), and /npcoliseum leaderboard for an all-time/weekly/daily ranking across every arena or just one, plus a personal stats screen.
• Crash-safe: a player who disconnects mid-match gets their real inventory back exactly as it was, even across a server restart.

Admin tools

• /npcoliseum admin givekit <id> — hand yourself a kit instantly to inspect it.
• /npcoliseum admin start <delay> / stop — force a match to start even if the arena isn't fully staffed, or force-stop one instantly (never counted on the leaderboard).

1. Drop NPColiseumPlugin-<version>.jar in plugins/ alongside NorrionProjectCorePlugin.
2. (Optional) Install WorldGuard first if you want arenas tied to a protected region.
3. /npcoliseum admin mob to build your first custom mob, /npcoliseum admin kits for a kit, then /npcoliseum admin arena to put it all together — no config file to touch for any of it.

Do I need WorldGuard? No — it's a soft dependency. Without it, an arena just has no region/flags screen; everything else (mobs, kits, waves, the match itself) works fine.

Can I edit an arena while a match is running in it? Yes, the editor is always available — changes apply the next time that arena's waves run.

What happens if a match gets force-stopped? Every player is teleported back and restored exactly like a normal match end, but it's never recorded on the leaderboard.

If there's a mob option, a wave behavior, or a kit mechanic you need and don't see here, come tell us on Discord.
