Arena

The Arena is a fixed roster of 30 NPC fighters, fought in strict order — beat one, the next unlocks. It's a low-stakes, repeatable grind: losing costs you nothing but the Energy you spent, so it's a safe way to build cash, EXP, and Reputation without any of the risk of real PvP Combat.

The Roster

Two tiers, 15 NPCs each, always fought in order:

The Arena — 15 regular fighters, Level 5 through Level 225.
Arena Elite — 15 tougher fighters, Level 240 through Level 440 (Eclipse, the final NPC).

You can't skip ahead or pick a target — beating an NPC unlocks the next one on the list, and Elite unlocks the moment you beat the 15th and final regular Arena fighter. Note this isn't a simple "win 15 fights" counter — since an already-unlocked NPC stays fightable for repeat rewards, you could easily rack up well past 15 wins while still stuck early in the order if you keep re-farming someone you've already cleared. What actually unlocks Elite is beating your way through all 15 in sequence, not the raw win total.

Fighting

Costs 5 Energy per fight, drawn from the same Energy pool as the Gym and Street — there's no separate Arena resource and no daily fight cap. You do need to be conscious to fight (health above 0) — get knocked out and you'll need the Hospital first.

Combat itself runs on the exact same engine as PvP — same stat formulas, same turn-by-turn resolution, your active Pet still fights in every 5th turn. NPCs don't carry a pet of their own and never equip a Weapon, Armor, or Relic — their stats come straight from their own fixed level.

An NPC you don't finish off stays wounded — their health carries over between attempts, so a fight you don't win outright is still progress toward finishing them next time.

Rewards

Cash and EXP — each NPC has its own fixed base reward. No Intel bonus applies here (that's a Street-only mechanic) — Arena's EXP is flat per NPC, not calculated the way PvP EXP is.
Reputation — a smaller, steadier gain than PvP: max(1, round(1.3 × NPC level^0.55)), in the direction of your own alignment. Losing or drawing never costs Reputation — Arena has no downside for a bad fight.
MCC Champion — +10% to both EXP and Reputation from Arena wins while you hold the title.
District control — if your alignment controls the Heights district, Arena EXP gets a small bonus on top.
Penthouse Lucky Pendant — an equipped, active Pendant adds +15% EXP to Arena wins.

On top of the normal per-fight reward, winning sometimes triggers a bonus roll — guaranteed on your first win against an NPC and every 25th win after that, plus a small random chance on any other win. It can hand out a cash/EXP multiplier on that fight, bonus Energy, Explore Turns, Scraps, Points, a permanent boost to your max Health, or — rarely — Donator days if you don't already have any active.

There's no item drop table — Arena never hands out Weapons, Armor, or Relics, only currency and resources.

Losing

Nothing but the Energy you already spent. No cash loss, no Reputation loss — the fight simply doesn't count as a win, and the NPC keeps whatever damage you did manage to land for next time.

Tips

Since losing costs nothing beyond the Energy, there's no reason to avoid pushing into tougher NPCs once you're geared up — worst case you just try again.
The special bonus roll is guaranteed on your very first win against each NPC, so working through fresh unlocks is worth doing even if the fight itself is close.
Arena Reputation gains are small compared to PvP, but they never put your own Reputation at risk the way attacking another player of your own alignment does.
Keep an active Pet in your carrier — it fights alongside you in Arena the same as it does in PvP.
