Knowledge Plans

Plans aren't treasures. They're notes someone took very seriously.

In short: Knowledge plans raise an island's resource production — and the travel speed of its fleets, if you have the matching research. A single plan is enough for that.

- Plans appear in your laboratory once it has reached level 6

- They're tied to the island, not to you

- Losing a battle can let an attacker plunder some of your plans

What are knowledge plans? #

Knowledge plans are an island-bound collection of insights. They don't boost everything, though: while your island holds a plan stockpile, its resource production rises and the researches that speed up travel (Navigation, Forced March) have a stronger effect — the latter only if you have actually researched them. The attack and defense of your troops and the base speed of your ships stay untouched. The bonus is a switch, not a ladder: a single plan already turns it fully on, and more plans or a higher laboratory do not make it any stronger.

Plans don't move between your islands. What you produce on the main island stays there. A side island with its own laboratory produces its own plans — separate accounts, separate effects.

How are plans produced? #

Once your laboratory reaches level 6, the island slowly starts producing plans. Every further laboratory level yields more plans per day — that only speeds up the resupply; the bonus itself does not grow. Your laboratory stores only as many knowledge plans as it has levels; anything beyond that is lost.

You don't trigger plan production manually. It runs in the background as soon as the conditions are met.

When are plans at risk? #

If you lose a battle on a plan-bearing island, the attacker may take a portion of your plans. The size of that portion depends on the strength ratio — a narrow win nets the attacker less than a clear one. The attacker also needs free space in the laboratory on the island they sailed from. With no laboratory or a full plan stockpile, they cannot loot plans; anything they cannot hold stays with the defender.

Achievements for plundering plans count the number of plans plundered, not the number of battles. Plans plundered in the past are not recounted retroactively.

When an island is conquered, its remaining plans pass to the new owner with it. The laboratory loses levels in the conquest. This reduces its space for plans: excess plans are lost. If no laboratory remains, no plans remain either.

Strategy #

• The laboratory pays off, but not in bonus size — a higher laboratory shortens research times and refills the plan stock faster; the plan bonus itself stays the same size
• Defense protects your plans — an island that looks easy to plunder becomes a plan magnet for attackers
• One plan is enough — as soon as a single plan sits on the island, the economy bonus is fully active; you don't have to research anything for it. A bigger stock does not strengthen it. Plunder alone cannot take your last plan, so the bonus stays active

You can view your current plan stockpile directly in your island's Research tab — there is a dedicated section for knowledge plans, and it also tells you whether your plan bonus is currently active.
