Precision blueprints are one of those things players usually ignore at first, mostly because they start off looking small. You begin with lower colors like gray and slowly work your way up through green, blue, purple, and eventually gold.
But once you start leveling them, you realize they affect all your rallies. The boost adds up to a pretty big power increase across your entire army.
Tiles Survive Precision Blueprints Guide – Where to Get Them and How They Work
How Upgrading Works
Upgrading blueprints happens in stages. You level them up to a certain point, and once they reach that level, you can upgrade them to the next color tier.
Every time you make that jump, the cost is higher, but after the upgrade, the cost drops again for normal leveling. Each color tier keeps the benefits from the previous one while adding stronger stats.
Different Stats Per Collection
Each blueprint collection gives different stats. Some focus more on attack, while others provide different types of boosts.
So depending on what you need most, you’ll usually pay attention to which collections improve attack or other important stats.
Roaming Infected Drops
One of the easiest ways to get blueprints is by fighting roaming infected. The first time you defeat one, it gives a small blueprint reward.
Even if you can’t handle higher levels, attacking lower ones still works, and repeating fights slowly adds up over time.
Paradise Event Rewards
Another big source is the Paradise event. Spinning the wheel and completing progress milestones can give a decent number of blueprints.
Each reward chest along the way provides some, and completing full progress stages gives larger blueprint rewards.
KVK and Arcadia Sources
In some cases, you can also get blueprints from KVK rewards or Arcadia battles. Higher damage rankings in Arcadia can lead to better rewards that include blueprint-related items.
These aren’t always frequent, but they still contribute over time.
Converting Blueprint Chests
Blueprint chests can also be converted into actual blueprints. Opening multiple chests at once can quickly increase your blueprint count.
This becomes especially useful when you’re close to reaching the amount needed for an upgrade.
The reason players keep working on blueprints is simple — they boost overall rally power, not just one hero or one troop type.
Because the bonuses apply broadly, continuing to upgrade them steadily makes a noticeable difference in combat strength over time.
