There are some points in the world boss strategy where the usual theories of boss hunting do not apply.

I will explain them here.

How to increase damage

Notes (Important)

Due to a specification change on 2024/9/20, the following changes have been made

– Increased damage dealt by ground troops to the Bird of Hurricane.
– Increased damage dealt by ranged troops to the Thunder Scorpion.

When fighting Bird of Hurricane & Thunder Scorpion,
In this article, “Mounted Troops” should be replaced with “Ground Troops” and “Ranged Troops,” respectively.
The damage will be higher than when attacking with Mounted Troops.
(However, this does not apply if Mounted Troops buff is extremely higher.)

1) Attack with high level mounted troops

This is the same as the usual theory of monster hunting.
Since cavalry has the highest attack strength, other types of troops are unnecessary.

If the highest level mounted troops are scarce, include the lower levels as well

However, there is a slight difference.
In normal monster hunting, it is better to have only one level of mounted troops to avoid unnecessary wounding, but for world bosses, damage is more important than the number of wounded, so if there is room in the march, it is better to have other levels of mounted troops join.

In some cases, include more lower levels than the highest level

As shown in the test results below, more lower level troops may cause more damage than more highest level troops.

If you have only a few troops at the highest level, you may want to try several times with different numbers of troops in the lower levels.

2) Increase the number of troops (increase march size)

This is also the same as the usual theory of monster hunting. The more troops there are, the more damage will be inflicted. Use items, monarch gear, etc. to increase march size.

3) Increase attack, defense, HP of mounted troops

Attack strength is obviously necessary,

but unlike normal boss battles, raising defense and HP will increase damage in the case of world bosses.

The reason for this is that battles with world bosses are turn-based, and the battle continues until our wounding rate reaches a certain %.
(0.8% without Monarch Talent Lv6 Mortality)
(0.4% with Monarch Talent Lv6 Mortality)

Test results: attacked with completely different troops, generals, and research

* Monarch Talent Lv 6 Mortality – None

This increases the number of attacks the more durable you are.
As a result, the damage per turn remains the same, but the total damage increases.

See the following article for more information on how to increase attack strength, defense, and HP, i.e., means of increasing buffs.

Buff / Debuff – Basic Guide

Supplement: Does the damage change with or without mortality?

Test results: Attacks with and without mortality only

-> Damage remained the same.

4) Boost Against-Monster Buffs & Normal Buffs

There are two types of buffs: normal buffs and against-monster buffs, both of which are effective against world bosses.

Test result: attack by changing only the skill book.

Therefore, it is best to give the general a “mounted troops attack” and a “mounted troops attack against monster” skill book. If both are Lv4, the increase is 25% + 45% = 70%.

5) Attack with a boss-hunting general with a high mounted troops buff

Please refer to the following article on high buff generals.

Best of Mounted PvP General

(vs. Bird of Hurricane)

Best of Ground PvP General

(vs. Thunder Scorpion)

Best of Ranged PvP General

6) Troops of subordinate cities

When a subordinate city is brought into the battle, attacks by troops of the subordinate city will increase the damage. (Although it is quite small.)

7) Monarch Talent

When the following of the Monarch Talent is enabled, the more subordinate cities enter the battle, the more the attack, HP, and defense of the main city troops increase, and the more damage they do. (Not troops of subordinate cities)

• Lv22 subordinate city attack
• Lv35 subordinate city HP
• Lv40 subordinate city defense

7-1) Test Result: Damage Change by Monarch Talent

Attacked Thunder Scorpion. (Effective debuff: attack and defense of mounted troops)

Setting

• Number of troops in subordinate city is 0 (dismissed just before attack).
  • Damage caused by troops of subordinate cities is eliminated.

• Mayor: Sanada Yukimura (Skill: Against Monsters Debuff: Defense -5%)
• Mayor Equipment
  • Sanada Yukimura A (for Against-monster debuff)
    • Dragon Equipment Set 4 (Monster Attack & Defense -10%)
    • General Equipment Set 2 (Monster Attack -5%)
  • Sanada Yukimura B (for normal debuff)
    • Full Akemenidae Set (mounted troops attack -35%, mounted troops defense -35%, all troops attack -15%)

Result 1

• Monarch Talent
  • Lv22 subordinate city attack – None
  • Lv35 subordinate city HP – None

-> Damage remains the same.

Result 2

• Monarch Talent
  • Lv22 subordinate city attack – Use
  • Lv35 subordinate city HP – Use

-> Damage changed.

8) Enhance debuffs

8-1) There are debuffs that work against each world boss

• Hurricane Bird : Attack & Defense of Ranged Troops
• Thunder Scorpion : Attack & Defense of Mounted Troops
• Behemoth King : Attack & Defense of Ground Troops
• Lord of Lava: Attack & Defense of Siege Machines

• Maximum debuff reduction: 250% for all world bosses

The above information can be found on the description screen of each world boss.

Therefore, it is advisable to raise the debuff of the relevant troop type as much as possible by general’s equipment and research, etc.

For more information on the basics of debuffs, including how to increase debuffs, see the following article.
Buff / Debuff – Basic Guide

Attack debuffs also increase damage

At first glance, only defensive debuffs seem to be effective in increasing damage. However, as mentioned in section 3, attack debuffs also contribute to increased damage, since you can attack until your rate of wounds reaches 0.8% (or 0.4%).

8-2) Against-monsters debuffs

There are two types of debuffs: normal debuffs and against-monster debuffs.

(against-monster debuffs = Sanada Yukimura’s skills, etc.)

Against-monster debuffs do not work on world boss. (Tested 7/9/2023)

(This has been a silent specification change many times, and should continue to be noted. Originally it did not work initially, but then became effective, and with all mayors being Sanada Yukimura (with debuff of sets of 4 dragon equipment), the score was more than doubled. And now it doesn’t work again.)

8-3) Debuff by subordinate cities

In case of solo, subordinate cities can be entered into the battle.

The debuff of the participating mayor will work on the world boss.

However, it does not work if the subordinate city has 0 troops.

Also, please note that there are cases where the debuff does not work due to a glitch.

If troops are created after the subordinate city has 0 troops and the application is not rebooted afterwards, the debuff will not work.

8-3-1) Test result: whether the mayor’s debuff works or not

attacked the Behemoth King. (Effective debuff: Ground Attack & Defense)

Setting

• Monarch Talent
  • Lv22 subordinate city attack – None
  • Lv35 subordinate city HP – None
  • Lv40 subordinate city defense – None
  • When these are enabled, the attack, HP, and defense of the main city’s troops will increase when subordinate cities enter the battle, and the damage caused by the main city’s troops will increase.

• Mayor: Empress Dowager Cixi (Skill: Normal Debuff: Ground Defense -30%)
• Mayor Equipment: None

Tests 1 and 2 differ only with and without mayors. I wanted to see the damage change with only the mayor debuff turned on and off, so I set the number of troops to 0 to eliminate damage caused by subordinate city troops. As a result, it seems as if the mayoral debuff is not working because the damage is unchanged. However, the question remains whether the mayor debuff does not work because the number of troops is 0.

Therefore, after Test 2, I waited until a sufficient number of troops (3) had been created to prevent the damage from occurring, and then conducted Test 3. However, the damage is the same as in test 2, so it appears as if the mayor debuff is not working. (Note that I did not restart after the troops were created.)

Also, regarding the damage caused by the attacks of the three soldiers. Tests 4 and 5 differ only in the number of troops in subordinate cities. This shows that even if there are more than 1,500 soldiers in a subordinate city, the damage difference is only 1. This indicates that the damage caused by three soldiers in a subordinate city is close to zero.

Second, tests 3 and 4 differ only in whether the application was restarted after the troops were created after the troops of the subordinate city were reduced to zero. This is because I suspected that if the app was not restarted, the troops would be internally processed as zero and the mayor debuff would be disabled.

The result was a difference in damage (8,244 damage). We know from comparing Tests 4 and 5 that such a damage difference cannot be caused by the attack of three soldiers alone. And there is no other damage factor other than the mayor debuff. Restarting the application shows that the three soldiers became active and the mayor debuff became effective.

These results indicate that the mayor debuff works and that the mayor debuff does not work unless the application is restarted after the number of soldiers reaches zero.

* In addition, I have confirmed that this problem of the mayor debuff not taking effect unless the app is restarted also occurs in battlefields such as Battle of Gaugamela (BoG) and Constantinople (BoC).

9) Attacking in a rally (conditions exist)

A minimum keep level 36 is required, but if you have already researched “buffs for rallying” at the Military Academy, you may (*) be able to do more damage by rallying than by attacking solo.

(* In the case of a rally, subordinate cities cannot participate in the rally, so the buff by the monarch talent will not be effective. This is a negative effect.)

How to kill a World Boss

Pay attention to the time limit

The World Boss moves to a new location every certain amount of time.
When it does, it recovers its HP, so you need to deal 100% of the damage by then.

Number of troops required to kill, etc

Information wanted!

I am looking for information about the conditions to inflict more than 1% damage.
I would appreciate it if you could send it to me in the comments section or via DM on Twitter.

Examples

– Percentage reduced
– Damage
– Level of troops, Number of troops
– Buff of Mounted troops Attack (%)
etc.

Reference historical data: number of troops, damage, % reduced

The following data is as of 2021. The specifications have changed since then and it seems to have become stronger, and now it is not as follows.

• t13 cavalry / number of troops 2M -> 1B damage
• t14 cavalry / number of troops 2.1M / mounted troops attack buff 1,100% -> 1.5B damage

• 1.8B Damage -> 1%

Other basic information

• World Bosses appear every week for 48 hours.
• The type of World Boss that appears changes every week.
• World Bosses appear randomly at some location on the world map.
• There are rankings based on the damage inflicted by individuals and by alliances, and the top players will receive rewards.
• You can never lose to a World Boss.
• Wounded troops do not occur. (Internally, they are incurred during the battle, and when the number of wounded reaches a certain number, the battle ends, but they are reduced to zero wounded when the battle ends.)
• Rewards will appear on the world map when the HP of a world boss is reduced to 80%, 60%, 40%, 20%, or 0%.

Number of times you can attack

The number of times you can attack is fixed, and you can attack up to 5 times for free.
After that, you can attack by paying Gems to purchase chances.
