Zones & PvP

A zone is a polygon laid over the grid that overrides what happens inside it: how tough the mobs are, which faction owns it, and whether players can attack each other. Zones are how you sculpt difficulty and pick the fights worth having.

PvP engage: 25% / decision
Kill reward: +8 fun
Level gate: +3

How zones work

Shape — a polygon of three or more corners; a cell belongs if its centre falls inside.
Level range — sets the min/max level mobs spawn at, intersected with the spawner's own range.
Faction — optionally owned by a side, or left neutral.
PvP — a per-zone toggle, only live when the PvP feature is unlocked.

Player-versus-player

Inside an active PvP zone, the combat brain gains two new branches — retaliation and aggression:

PvP rule	Value
Engage chance	25% per decision to attack a nearby enemy
Kill reward	+8 fun
Death penalty	−5 fun
Level gate	won't attack anyone more than 3 levels above
Both-ends rule	the target must also be on PvP-active ground

Retaliation vs aggression

There are two ways a fight starts. If an adventurer is hit by an enemy faction, it retaliates once the target is validated as alive, hostile, and in the same zone. Otherwise it may go looking — scanning for nearby enemies and rolling the 25% engage chance. The level gate keeps low-levels from throwing themselves at untouchable targets.

PvP is opt-in by design: both attacker and victim must be standing on PvP-enabled ground, mirroring the classic contested-zone model.

Why factions stick

A balanced rivalry is some of the stickiest content an MMO has; a lopsided one bleeds half your server. Faction balance is a dial you watch and sometimes have to correct — by placing content and zones to pull population where it's needed.
