Tiles Survive Copper Clash Guide: Season III Lairs, Mines and Merit

For Tiles Survive chiefs entering Season III who want to understand Copper Clash and the Might of the Ocean tech tree before their rivals do, and play the faction system right from Day 1.

Season III, Noctis Descent, rewrites the competitive rules in Tiles Survive. Copper Clash puts your whole faction on the leaderboard. The new Might of the Ocean tech tree adds permanent Power that outlasts the event.

Most alliances go in unprepared. They miss one of the three Copper sources, leave XXL mines undefended, or rush the tech tree before their Clash position is stable. This guide covers all of it.

What Copper Clash is

Copper Clash is the flagship competitive event of Season III: a sustained, faction-wide war over one resource, Copper. It starts in Week 2 of the season and puts the top 8 alliances against each other in map-wide tile battles. Unlike earlier season modes, rankings are tracked at the faction level, not just the alliance level. Your own plays feed into your whole faction's standing.

Each map hosts six opponents, three from each side. Locations start at 200 points, and some high-value nodes start at 300. Action points are limited, so every attack decision counts. After Day 5, you can strike directly from your faction's core territory even without a tile connection.

Coordination is not optional. Alliances that talk, with defenders assigned to mines while attack squads push lairs, beat alliances that scatter. If your faction has no plan before Day 1, you are already behind.

Choosing your faction: Keeper or Breaker

Season III splits each server into two opposing factions, and your path choice shapes how you play through Copper Clash.

• Keeper of Light (60 to 70% of the alliance): research, resource generation and base development. Tech investments build up over the full season.
• Breaker of Shadows (30 to 40%): the PvP vanguard. Troop training, rally leading and map control.

Leadership should lock in the balance before any member picks a path. One wrong choice can leave the alliance lopsided in exactly the wrong direction at exactly the wrong moment.

Lairs, mines and Merit

Inside the Clash event there are two kinds of capturable tile plus your personal Merit track. Knowing how each works, and which to prioritize when, is where good alliances pull away from the rest.

Lairs: attack for points

Lairs give points for every successful attack. Hit them hard, capture fast, move on. They suit aggressive alliances that want quick leaderboard jumps. Alliance-wide damage to lairs also levels up event buffs for every member, so organized lair pushes are worth more than the raw points.

Mines: hold for ticks

Mines reward you for holding territory. After capture, you get ticking Copper points every minute, +1 or +2 depending on size. There are four tiers:

• Small (S): +1 per minute. Contest when unclaimed.
• Medium (M): +1 to 2 per minute. A good hold target.
• Large (L): +2 per minute. Prioritize defense.
• XX-Large (XXL): +2 per minute per node. The highest value. Defend at all costs.

New this season: each mine now shows both alliance and faction holders in a dropdown. Several alliances in the same faction can defend one node together, which is exactly how top factions hold XXL mines against pressure from several attackers.

After you capture a mine, move straight on to defending the next node next to it. Every undefended minute on an XXL mine is Copper you cannot get back.

Merit: your personal score

Merit tracks your own contribution. You get it by killing enemy troops and landing successful attacks. Rankings reset daily, so steady play across the event matters far more than one huge push on a single day. Reward thresholds unlock automatically when you reach them.

One hard rule: do not leave your alliance during the event. Your progress resets the moment you do, and there is no way to restore it.

Advanced strategy for competitive factions

• Use territory links early. Extend your attack range before the map locks. After Day 5 you can launch from faction core territory without tile connections, so plan your expansion before then.
• Guard your action points. Upgrade troops and heroes before the event starts so every action point turns into a near-certain win. Points wasted on losing attacks are gone and pull your rank down.
• Split roles across alliances. One alliance defends the XXL mine. Another pushes lairs. A third handles city control for passive income. Factions that do not coordinate leave points scattered across the map.
• Watch faction rankings live. The new faction leaderboard shows each state's Copper total. Find the states that are falling behind and talk to them. Sharing city control is the fastest no-cost catch-up there is.

Might of the Ocean: the new tech tree

Might of the Ocean arrived in the same update as Season III and is a permanent addition to Settlement Techs. Copper Clash resets between seasons. This tech tree does not. It gives lasting Power bonuses for Mariner-class heroes that carry into every future event. Every level you unlock stays into Season IV and beyond.

When to invest

The biggest mistake with a new tech tree is rushing in before the meta settles. Two weeks of patience lets the community find the nodes that give outsized value, and the ones that drain resources for little return.

Ignoring it completely in the first weeks is also a mistake. Permanent Power bonuses stack up, and late starters hand early investors a gap that grows every season.

The right approach: secure your Copper Clash basics first (troop readiness, hero formation, Power Plant level), then start steady Might of the Ocean investment once your Clash position is stable. Power Plant is still the main bottleneck. Every Might of the Ocean unlock depends on a Power Plant level high enough to keep electricity flowing to production. The Power Plant requirements guide covers the levels.

Keeper vs Breaker priority

• Keepers: put Might of the Ocean next to your Copper Clash research. Your power curve gains the most from stacking permanent tech bonuses. This is your natural path.
• Breakers: do not ignore the tree, but time your unlocks around active combat windows. Rushing tech mid-Clash can starve your troop training queues right when you need them most.

Rewards and why Copper Clash matters long term

Copper Clash is more than a weekly leaderboard. It is a progression multiplier for all of Season III. The faction ranking unlocks shared rewards that alliance rankings alone never could: hero fragments, permanent skins and Power boosts that can move your settlement two or three levels faster than normal grinding.

Season III decorations also now give extra stat bonuses as they level, so early ranking investment turns into real Power later in the season, not just cosmetic prestige.

Copper Clash in short

• Pull Copper from all three sources at once: Clash events, KVK wins and passive city income. Neglecting any one is how alliances stall.
• Lairs give fast leaderboard jumps through attacks. Mines give steady ticking income, and XXL nodes are the top targets that need constant defense.
• Merit resets daily. Steady fighting beats one-day pushes. Never leave the alliance mid-event.
• Faction coordination before Day 1 decides whether you run a plan or a scramble. Lock city control, mine defense squads and lair rotation before the event starts.
• Might of the Ocean is permanent. Invest after your Clash basics are stable, not instead of them.
