In this game, there is a unique level gameplay, which is the expedition in the campaign. It has different levels, and each level can provide different rewards such as wood and copper ore after being cleared. These resources are essential for pioneering, so newcomers must pass them. So how to pass them? This guide on the Dragonstone War levels will share passing techniques and directly share the methods for several more challenging levels to help everyone smoothly obtain the necessary resources.

I. Explanation of Campaign Rules
After clicking the campaign button on the main page, you enter the expedition. Currently, there are 15 chapters in the expedition, which will be unlocked based on the corresponding level of your main castle. Therefore, prioritizing the upgrade of the main castle level helps to quickly unlock more chapters, aiding in effectively obtaining resources. Among the 15 chapters, there are also different levels, each giving a one- to three-star evaluation after being cleared. As long as you successfully defeat the enemy, you can clear with one star, but to get high stars, you need to meet the level conditions. Although getting the total star rating will give more rewards, for newcomers who have not fully developed their heroes, troops, etc., in the early stage, just passing with low stars to accumulate resources, and then coming back to challenge again when the team becomes stronger, is sufficient.

II. Practical Techniques
Before entering the battle, you can get a lot of useful information for the fight on the pre-battle preparation page. The combat power at the top can help judge whether you need to improve. The enemy situation at the lower left corner allows you to check the types of troops and heroes in the enemy's level, thus adjusting your lineup to target the enemy's weaknesses. If the enemy's output hero is paired with a large number of rear troops, and the three-star condition of the level has certain requirements for our blood volume, it would be difficult to maintain our blood line by going head-on, easily leading to failing to meet the blood requirement due to excessive damage taken by the front row. At this point, it is recommended to use summoning-type heroes, using their summoned creatures to resist damage, reducing the direct damage received by the team. Adding an assassin role that can cut in will help prioritize solving the rear output, allowing for a smooth passage.

III. 3-2
Before the battle, first observe the enemy situation. The enemy has 6 elemental fire dragons, 5 resolute stone golems, and a 15th-level output general, presenting a certain difficulty. It is suggested to upgrade the main castle to level 10, and for heroes, choose a conventional combination of a front-line tank and a rear output, such as Sylis + Haro. If you lack materials for upgrading at this point, you can only upgrade the output type to level 27. If the damage is really insufficient, prioritize maintaining blood volume, and bring 6 sky soldiers to counter the elemental fire dragons. Fill the rest with logistics medical soldiers to ensure a blood volume advantage, and you can pass smoothly.

IV. 3-4
In this level, you can see that the enemy leader is a flying character, with monsters not having very high tiers, including 6 elemental fire dragons, 3 resolute stone golems, and 8 mighty acorns. Since there will be quite a few flyers, it is recommended to use sky soldiers, which can counter them, as the primary force. Acorns can be countered by drillers, and the least numerous stone golems can be ignored to pass directly.

V. 4-1
Starting from Chapter 4, there will be 2 armies, and the selected heroes will no longer be distinguished by teams. Therefore, at least 4 characters need to be cultivated. The specific choice can depend on the role's position. It is suggested to have 2 outputs, 1 tank or warrior, and 1 support or assassin. Upgrade the population to 37, and the commander points should be upgraded to level 9. In the first level, the enemy still has many flying monsters, so relying on sky soldiers as the main force is still effective.
VI. 5-1
The enemy composition in this level mainly includes ranged acorns paired with anti-air units and front-line control electromagnetic ants. Therefore, in our team composition, we must not choose flying units, as soldiers have a 30% damage bonus against air. A combination of front-line tanks and output is highly recommended. If there is a three-star requirement, carrying some healing units can increase the fault tolerance. For the front line, Mischievous Stone Golem is recommended, and for output, a unit with area effect, such as the driller, is recommended. It not only has low costs but also deals damage to enemies within a three-square range.

This concludes the guide on the Dragonstone War levels. The above mainly discussed passing techniques and methods for some levels. After reading and understanding, newcomers, as long as they follow this approach, enhance their own strength and lineup according to the enemy's combat power before passing, should be able to pass smoothly.
