Timing the Ring

The ring of dead tiles begins advancing at tick six hundred. Every decision in the second half of the match is shaped by that timer.

Dominion's ring mechanic is what keeps matches from stalling. Starting at tick six hundred — five minutes in — a ring of dead tiles advances inward from the map edge on a fixed interval. Any unit or building in a dead tile takes damage on each advance. By the ten-to-fourteen-minute mark the playable area is small enough that contact is forced.

The warning window

The ring warning fires before the first advance. Use this window to pull your army off the outermost rim of your territory and consolidate inside the future playable area. Outposts on the rim are fine for economy — they'll still produce until they get eaten — but don't have your main stack stranded out there when the first advance hits.

How the damage works

The engine applies ringDamagePerAdvance to everything in a dead tile on each advance. Advances happen every ringInitialIntervalticks — twenty-five seconds at the default interval. That's enough time for a garrisoned stack of Warriors to survive one or two advances, but not enough to weather a late-game full ring without losses. Plan to be inside the next ring before the advance, not after.

Positioning and pressure

Once the ring is active, the map tells you where the fight will be: the center. Anchor your front line on a choke that the ring will still contain in two minutes, not on tiles that are about to die. If you're ahead, this is your commit window — the opponent can't retreat anymore because there's nowhere to go. If you're behind, use the ring to force a favorable engagement: lure their army into your fortified position and let the ring eat their outer tiles while you trade on equal ground.

When to commit

If your army has mass parity (or better) and you know where their Capital is, commit. Dominion rewards the side that chooses the moment — stalling a losing economy while the ring closes just means you'll be fighting the final battle on smaller, worse ground. Capital captures take ten ticks; plan the push so you arrive with enough Warriors to survive the siege timer under any likely defensive response.
