Introduction

Yesterday the building upgrades level 23, 24 and 25 were introduced. In this guide we discuss these upgrades. We focus on the benefits, not the costs.

Cost Update

We have now filled in most of the resource, hammer and time costs, as well as the prerequisites. See our Building overview for the details per building.

Costs

The costs are high, even compared to upgrading your building to level 22. Even if you still had the trillions of required resources and millions of Legendary Hammers lying around, you will need to purchase a pack for Headquarters 23 Blueprint that is a requirement for upgrading your Headquarters to level 23. I don't know requirements for levels 24 and 25, but it is naieve to think you will be done with one pack, if the past is any indication it will be far from that.

There are some benefits that cannot be achieved anyway else, which we will discuss below, so irrespective of the high cost, it will be worth it to get the competitive edge (or not fall behind).

Benefits

Find below a table with the boosts associated with the upgrade to levels 23 to 25 for each building. In the second column you see the cumulative boost until level 22, in the next columns the incremental lvl 23, 24 and 25 boosts, and in the last column the cumulative boosts for lvl 1 to 25. This way you can see what you get from the lvl 23, 24 and 25 boosts and see the total you have once you completed the lvl 25 upgrade.

Analysis

As you can see in the table above for a lot of buildings the boosts for level 23-25 are quite small, considering the tremendous cost, but also compared to the additional boosts for the earlier levels.

The Farm, Iron Mine, Oil Well and Quarry all give a good increase in capacity and production compared to earlier levels. Still, what I noted when level 22 was introduced is even more true now, it will take a long time before the increased production rates will pay back the trillions of resources you need to invest for these upgrades.

The Armory gives a significant manufacturing speed boost and a small Prototype Gear Duration Boost. Although the manufacturing speed boost is significant, spending a few more or less speed ups will not matter to most players. Being able to use an expensive Prototype Gear longer will make a difference.

The Bank increases the coin base capacity and production, but nothing spectacular. There is a small training speed increase. The combat boosts are more significant, with a 300% Armor Piercing Boost and 100% Troop Attack boost.

The Death Row gives a major increase in combat boosts compared to level 22, going from 40% to 500%.

The Embassy increases the capacity significant, more or less in line with the increase in Deployment Size. The Embassy defense bonus has a significant increase from 15% to 50%.

The Hall of Heroes increase in Commander XP Modifier is average, the Commander XP Retention increases to 99%, but one will still revive his Commander instead of hiring a new one. There are a fair number of extra Skill and Rebel Skill points as well.

The Headquarters level 23-25 upgrade gives a huge benefit, increasing to a total Deployment Size of 1,850,000. This huge from the previous 350,000 and will make many targets previously too strong for solo attacks now easy.

The Hospital gives a major increase in Troop Health, from 7% to 100%. The additional Hospital Capacity is also significant, going from 50,000 to 200,000 per hospital.

The Prison gives an increase in the (Advanced) Troop Attack boosts for holding commanders. The maximum boost increases from 35% to 150%.

The Radar Station introduces a new feature at level 23, it gives insight in the research a target has completed. In addition the troop attack penalty that incoming marches suffer increases from 12% to 50%.

The Research Facility gives another 30% Research Speed increase to a total of 60%.

The Trading Post increases the Trading Capacity a lot to 10,000,000, while the Tax stays the same. The (Gold) Gathering, Troop Load and Trade Deployment Speed boosts have an average increase.

The Training Grounds provide a new Accuracy boost, a total of 300% at Level 25. The troop defense bonus is relatively small, going from 12% to 20%. The training queue increases significant from 10,000 to 40,000, but probably most players have other ways to increase the training queue already.

The Walls give relatively large boosts in the Trap Capacity and Trap Attack and Defense, but since the importance of Troops compared to Traps only becomes higher, these are not so relevant.

The War Room gives a huge increase in Rally Capacity, from 2,500,000 to 14,500,000. This is a large difference, trap accounts have some work to do to adapt to this new reality.

The Warehouse capacity is increased from 10 million to 1.61 billion. A huge increase, but considering you need trillions to do these building upgrades, it is still small.

Prerequisities

Like with level 22 it is again the War Room that is the most important addition. I don't know the prerequisites of level 24 and 25 yet, but for level 23 the War Room has a total of 7 prerequisite buildings.

In general there seems to be less consistency with respect to prerequisites of lower levels of the buildings.

Conclusion

There are some benefits of the Building levels 23-25 upgrade that are worth it, no matter the costs (for those willing to pay), mostly the increased Deployment and Rally Size. A lot of the others are not worth it, but these two are game changers.
