Kingdoms & Lords In-App Purchase Guide

Gameloft’s previous Xbox Windows Phone 8 release Six-Guns had so many different in-app purchases that we published a lengthy guide just to cover them all. Seriously, virtually every aspect of that game had an IAP component, with some feeling less optional than others. The purchase model diminished what would otherwise be one of the best action games on the platform (though I still enjoyed it).

Kingdoms & Lords takes a much different approach, as only one thing costs real money: diamonds. Players can earn the sparkly gems by leveling up and completing story battles against bosses, but that’s about it. Run out and you might be inclined to buy more. Just what should you spend them on, anyway? Read our latest In-App Purchase guide to find out!

Diamond Packages:

  • A Handful of Diamonds –15 Diamonds – $1.99 (7.5 diamonds per dollar)
  • A Bag of Diamonds – 40 Diamonds – $4.99 (8 diamonds per dollar)
  • A Bucket of Diamonds – 85 Diamonds – $9.99 (8.5 diamonds per dollar)
  • A Chest of Diamonds – 175 Diamonds – $19.99 (8.75 diamonds per dollar)
  • A Handcart of Diamonds – 450 Diamonds – $49.99 (9 diamonds per dollar)
  • A Tramcar of Diamonds – 1,000 Diamonds – $99.99 (10 diamonds per dollar)

Now let’s go over the many ways to spend diamonds and which ones are most productive.

Speeding up time-based process

Kingdoms & Lords for Windows Phone

Several aspects of the game require real-time to complete, including:

  • buildings that produce gold on a timer
  • crop growth
  • resource production (wood, stones, and wool)
  • unit production
  • unit upgrade research

However, each of these is a poor use for diamonds. You’d burn through them so fast by using them for speed ups, and you wouldn’t be any better off than had you just waited.

Energy is a consumable resource that refills at a rate of 1 unit every two minutes and 30 seconds.

Many actions consume energy, such as: collecting gold from buildings, harvesting resources and crops, harvesting resources from the wild such as trees and animals, engaging in story battles, and attacking random opponents. It does not cost energy to plant crops or start resource production, “Revenge” attack a random opponent who attacked you first, or visit or invade someone from your friends list.

Energy can be purchased in the following quantities:

  • 5 Energy Units – 5 Diamonds
  • 10 Energy Units – 8 Diamonds
  • 15 Energy Units – 10 Diamonds
  • 25 Energy Units – 15 Diamonds

Like spending diamonds to speed up production, buying energy is wasteful. Your energy will fill up over time anyway, so don’t squander a precious resource just to save a few minutes.

Instead of selling coins as an In-App Purchase, coins just cost diamonds.

  • 1,000 Coins – 10 Diamonds
  • 2,000 Coins – 18 Diamonds
  • 10,000 Coins – 80 Diamonds

The coin prices are – frankly – ridiculous. You’re so much better off just earning coins the old fashioned way.

How best to rake in the coins then? By farming crops! You’ll find Homestead buildings under Production, where they cost 400 coins each. You should purchase as many homesteads as possible – basically one or two for every unit of energy you can currently hold.

Plant crops constantly and collect the riches from them before they wilt, cutting into your profits. If you’ve planted more crops than you have energy to pick them with, either pick up a little extra energy by visiting friends or come back in an hour or two when your energy has refilled. Keep doing this throughout the course of the game and you should be able to afford one land expansion per day, if not more.

Magic Cards

Single-use magic cards are used in battle against CPU opponents or other players. They provide a variety of beneficial effects such as damaging the opponent’s team or healing your own. Sometimes they’ll make the difference between losing to a superior force and coming out on top.

Magic cards exclusively cost gems; you can’t buy them with coins. You could buy a few cards with gems, but they’re so temporary that you’re better off getting them another way. See, friends can gift magic cards to each other for free. If you and a few friends send magic back and forth to each other, you’ll seldom run short during those tricky battles. Players can also win a couple of spells from the free daily lottery.

Premium buildings

Kingdoms & Lords for Windows Phone

Several of the game’s buildings come in both regular and premium varieties, the latter costing gems. Players can choose between premium houses, production facilities, and even research facilities. Better houses pay more coins, better research facilities complete research faster, and production facilities both finish faster and pay out slightly more coins or resources.

Premium buildings are good, but they’re not really worth spending diamonds on. They do allow you to be more productive in a shorter time, but it’s not like anyone could afford to populate a whole kingdom with premium farms or something. You’re better off buying tons of homesteads and other facilities with coins instead.

Premium Heroes

Kingdoms & Lords for Windows Phone

After leveling up enough to purchase the Tavern, players gain access to heroes as military units. The selection of heroes is mostly comprised of the campaign’s bosses, who become available for purchase after being defeated.

Only a few heroes like the Evil Monk cost coins to unlock, though. The rest require massive quantities of diamonds to unlock. If you really get into the competitive aspect of the game, you might enjoy having one of those premium warriors on your team. But heroes have a cooldown period after every battle. You can’t use before the cooldown ends unless you pony up more diamonds – not a good idea.

Surely there must be something worthwhile to spend those diamonds on, right? That something is research.

After purchasing a Training Field, players can research upgrades for any military unit in the game. To actually unlock the ability to upgrade a unit, you’ll first need to acquire sufficient quantities of four upgrade materials.

These materials can be bought outright with diamonds, but you can get them two other ways as well:

  • Select the unit you want to upgrade from the Training Field and then request the necessary materials from your friends
  • Visit and invade friends’ villages to earn stars. Those stars can be spent on upgrade materials in the black market of the store.

So Windows Phone gamers with friends can get around the need to unlock a unit for upgrading through social means. That unit’s upgrades can then be purchased with gold. However, each unit’s seventh and final upgrade can only be purchased with diamonds.

That’s what you should spend diamonds on; unlocking your units’ ultimate upgrades. But don’t do this with every single unit in your command. Early units will quickly be outclassed by units that unlock at high levels, even when upgraded. If you don’t want to spend diamonds on a unit that will eventually be retired, you should save them for the final iterations of each unit type.


Diamonds can be spent on a few more things like reviving fallen units after battle, decorations for your kingdom, land upgrades (which also sell for coins), or spare units. All of these things are frivolities – never spend diamonds on something that can be accomplished with gold or patience.

Kingdoms are a gamer’s best friend

Kingdoms & Lords for Windows Phone

The decision to buy diamonds or not comes down to how much you like Kingdoms & Lords’ battle system. If you love fighting other players, the advantages from premium heroes and fully upgraded units are hard to beat. The final boss is also quite tough, so you might want an edge there as well. Players who aren’t concerned about finishing the campaign or the competitive aspect can probably make do without spending.

Also, keep in mind that progress made in this version of the game will be shared with the Windows 8 version that releases later this year. And your progress is protected by a cloud save, so there's no danger of making a purchase and then losing it when you switch devices.

That wraps up our In-App Purchase guide. We’ll have our full Kingdoms & Lords review later this week!
