Blueprints are special content items that you can get from Random Rewards and can be used to get discounts when you research new tanks. The higher the vehicle Tier, the more Blueprints it’s made up of and with every Blueprint you receive, your discount grows. This means if you collect every single Blueprint of a specific tank, you will receive a 100% XP discount on the research cost of the vehicle.
You don’t have to collect all the Blueprints to take advantage of them, but the more you have, the bigger the discount you will receive. Blueprints will drop at random and are available for vehicles of all branches and nations from Tier II to Tier X, including vehicles that you have already researched. To make it easier for you to track the number of collected Blueprints, brand new special progress bars have been introduced and divided into sections. After receiving a Blueprint, one of the respective sections will be filled in.
If you get a Blueprint for a vehicle, which you have either researched or have all the necessary Blueprints already, it will turn into a “national” or a “universal” Blueprint. National Blueprints can be used on any vehicle of their respective nation, while universal Blueprints can be used on any vehicle of any nation.
There are also plans to introduce an opportunity to transform Blueprints you don’t need into those that you are looking out for. Please note: you can convert only “national” and “universal” Blueprints, but Blueprints that you already have for a specific tank cannot be converted. You may find out that you already have a discount for some vehicles right in your Research tab.
Blueprint Costs by Tier
The advantage of using Blueprints is the fact you can earn them playing on any vehicle, meaning you don’t have to grind a specific vehicle to get blueprints for it. Players won’t be able to research vehicles at random, by this I mean you can’t just skip the whole branch and just research the Tier X. Players are still required to research the previous vehicles, by either using Experience or Blueprints. But while it might be an advantage to use blueprints, getting them enough of them it will be yet another grind, mainly due to the cost.
A Tier X vehicle will cost 12 Tank Fragments, and each fragment will cost 12 Universal and 4 National Fragments, so a total of 144 Universal and 48 National Fragments will be required to research a single vehicle. Nonetheless, having blueprints is a good step forward to have experience discounts for example, so in my opinion a good new addition to the game.
