War and Order Packs are in game items which you can buy for real life money. This game is not exactly pay to win, everything can be done without spending any money if you dedicate enough time to it. But, if you would like to spend money, I will list some things that are CRAZY good value and are absolutely a must buy if you intend to spend some money.
You can check what these purchases contain in game, I will just rate them on my experience. There are a lot more War and Order Packs than these, but these are all fairly good value both their lowest price versions and up to the highest price.
New Lord Special Pack (1$) – Great to buy when you start on a new realm, 1$ is REALLY cheap and it gets you quite a few items that help you speed castle levels on day 1.
Growth fund ($10) – This is a new type of in game purchase they added, you only get an option to buy one if you have started an account in realm 400+ (if you are moving from an older realm below 400, you need to install the game on another phone in order for the game to set you in a realm that has been out after realm 400, and then move the castle to your desired realm. This purchase is GOD VALUE, it gives you a ton of gems when you reach a certain Castle level. NOTE you can only buy the growth fund for the first 7 days since you started.
Avenger Pack ($5) – overall pretty good pack
Daily Special Speedup ($2) – has nice speed ups, worth it for sure.
Fire Sale Speedup Pack ($5) – has nice speed ups, worth it for sure.
Monthly Pack ($20)- very useful pack, you get 1000 gems and some speed ups and a stamina pot every day for 30 days (total 30,000 gems).
Glimmering Gems Level 1 and 2 ($10, $20) – very useful pack, they appear only once in a month so make sure to grab one, $10 for 12,000 gems is really good value.
BasicMaterials 1 ($5) – good value, gets you materials for gear
Rare Speedup 1 ($5) – good speed up value
Power up 1 ($5) – good value for recruitment
Beast Skill 1 ($5) – good value for your beast, you get the Beast Skill chests which are hard to find, each Beast Skill chest grants you a skill fragment, when you get 20 of the same fragment you unlock a new skill for your Beast. More about Beast Skills HERE.
Excellent Team Elite War Pack 1 ($5) – good value
Mid-Autumn Sale 1 ($5) – good value
Exquisite Speedup 1 ($5) – good value for speed ups
Alliance pack 1 ($5) – really good value, gives you resources, gems, speed ups Alliance honor, and most importantly it also sends some rewards to all of your Alliance members (speed ups). It is also excellent for building Alliance castle on day 1 of a new realm and getting enough Alliance points to place flags, more about that on HERE.
If I had 31$ to spend, the best buy would definitely be Growth fund, Monthly pack, and $1 New lord special pack. Though, if you already have monthly pack active and glimmering packs are out, I would buy glimmering pack level 1, and level 2 if I had another $10.
I AM IN NO WAY PROMOTING WAR AND ORDER IN-GAME PURCHASES, THIS IS JUST FOR INFORMATIONAL PURPOSES, IF SOMEONE SPENDS MONEY IN THIS GAME AT LEAST THEY SHOULD GET THE MOST OUT OF IT.
