Walkthrough for Difficult Floors
On 2F, Place Evan in the Front Row
| Floor | Enemy Team | Best Team |
|---|---|---|
Floor 2 | | |
On 2F, the Front Row is inflicted with ATK/Deal Damage/Defense Reduction, and if you decrease the number of units in the Back Row, you'll be easily defeated by a skill that increases Deal Damage by 500%. Place Evan only in the Front Row, and place the rest of your team in the Back Row.
Dragonflame can't be Blocked with Burn Immunity
Since Dragonflame cannot be completely blocked due to the Buff Turn Reduction on Basic Attacks, It's better to aim for a quick battle with two Attackers, Xiao Qiao and Pascal, rather than trying to hold out with Burn Immunity.
2F - Additional Rules

On 4F, Attack with Poison and Bleed, Defend with Taunt x Damage Immunity
| Floor | Enemy Team | Best Team |
|---|---|---|
Floor 4 | | |
On 4F, skill damage is not very effective due to the enemy's Damage Resistance, so attack using Bai Jiao's Poison and Bleed, as well as single-target attacks from Daisy and Xiao Qiao. The enemy's single-target skill has high damage, so it is recommended to defend with Ryan's or Li's Taunt and Physical Attack Reduction.
Without Taunt, Clearing is Possible
If your attackers have high damage output and you can aim for a quick battle, you can also clear without Taunt and Physical Attack Reduction by using Velika to increase the skill rotation rate. Taunt is best for a stable clear while Velika is best if you're aiming for a quick clear.

On F6, Quickly Strip the Damage Immunity
| Floor | Enemy Team | Best Team |
|---|---|---|
Floor 6 | | |
On Floor 6, strip the 30-hit damage immunity as quickly as possible with Bai Jiao's Poison/Bleed or multi-hit heroes like Lu Bu and Kyle, then defeat the enemy with Shane in the back row. Due to the Unable to Recover rule, it's best to endure with a Barrier from heroes like Evan when your HP is low.
6F - Additional Rules

On F8, Aim for Rosie in the Back Row
| Floor | Enemy Team | Best Team |
|---|---|---|
Floor 8 | | |
For Floor 8, aim for Rosie in the Back Row by increasing Weakness Hit Chance with Biscuit or Rachel. Strip away Damage Immunity with Elysia's or Miho's Buff Reduction, and it's best to use Elysia for Debuff Removal to counter Death.
 Tips! | Due to Debuff Immunity, you can't apply Asura's Focus Target, so you need to attack with Weakness Hits. |
|---|
Overpower Enemies with High Damage
If your attacker's damage is high enough, you can also overpower the enemies by boosting damage with heroes like Melia or Xiao Qiao. Since the goal is to finish them off with two uses of Pascal's Upper Skill before Death is applied twice, you won't need Elysia to counter Death or Velika for her Cooldown Reduction.
8F - Additional Rules

On F10, Use Hero with Unable to Recover
| Floor | Enemy Team | Your Team |
|---|---|---|
| Floor 10 | | |
For Floor 10, Use Heroes with Unable to Recover like Chloe to prevent the enemy from recovering HP via skills, Life Drain, and the 100% HP recovery triggered by Authority. Be careful: if Unable to Recover is not applied right before Authority activates, the enemy will restore full HP, and you will have to start over.
3-Turn Buff Duration Reduction is Necessary
Every time the enemy's HP decreases by 25%, they gain 3 turns of Damage Immunity. If they use Skill 2 during this immunity, they gain an effect that deals additional Ignore Defense damage with every attack. Adopt Heroes capable of 3-turn buff reduction like Rudy, along with Velika for Cooldown Reduction.

On F12, Remain Healing and Aim for a Quick Clear
| Floor | Enemy Team | Best Team |
|---|---|---|
Floor 12 | | |
On Floor 12, the 3 enemies inflict Dragonflame and Burn, but you cannot use Damage Immunity due to the Burn Immunity nullification rule. Therefore, while healing with Sun Wukong or Lina, you should aim to defeat the enemies as quickly as possible.
Clear Barriers with Buff Turn Reduction or Buff Removal
The enemy Velika creates a Barrier when her HP is below half. Clear it with Miho's buff turn reduction or Biscuit's Buff Removal.

On 14F, Use Barriers to Counter Pierced Damage
| Floor | Enemy Team | Recommended Team |
|---|---|---|
Floor 14 | | |
On Floor 14, you will receive 3,000 fixed Pierce damage each time you defeat a non-boss enemy. You need to withstand this up to 8 times, so let's defeat them one by one while activating the Barrier from Branze & Bransel.
The additional rule, Souldeath, can be removed with Debuff Removal, so removing it will make it easier to survive with skills like Revive.
| Tips! | Be careful, as you may not be able to withstand the damage with your Barrier if you defeat all the enemies at once with Lu Bu's consecutive skill activations! |
|---|
Regroup with Debuff Removal
You will be inflicted with debuffs when defeating enemies other than Chancellor, and from Chancellor himself: Defense Reduction from his Skill 1, and Increased Miss Chance and Attack Reduction from his Skill 2. Once you've created a 5-on-1 situation against Chancellor, it's best to use Elysia to remove the debuffs as this will make things better.
Attack the Boss by Applying Durability Debuffs
Once you defeat everyone except Chancellor, increase your attacker's damage by focusing on durability debuffs and attack Chancellor. When his HP drops below half, he will gain a 2-turn Damage Immunity, so remove it with the buff duration reduction skill from Elysia or Branze & Bransel.
| Tips! | He will use Buff Removal, so be careful with the timing of your damage buffs. |

Juri's Souldeath is Best for 15F, 17F, and 19F
| Floor | Enemy Team | Best Team |
|---|---|---|
Floor 15 | | |
Rosie's Revive skill is a nuisance on floors 15, 17, and 19, so use Juri's Souldeath when the enemy's HP is low. While it is possible to clear with a Physical team, it is especially recommended to challenge floors 15 and 19 with a Magic Party that includes Mercure.

On 16F, Switch between Physical and Magic
| Floor | Enemy Team | Best Team |
|---|---|---|
Floor 16 | | |
On 16F, Rahkun gains Magic Resistance when he uses his first skill and Physical Resistance when he uses his second. We recommend attacking with Kyle, a wide-range Physical attacker, and Sun Wukong, a Magic attacker who can also heal, switching between them based on the situation.
| Tips! | Based on the enemy's skill cooldowns, there is slightly more time when Physical attacks are effective, so it's also a valid strategy to go without Sun Wukong and bring 3 Attack-type heroes such as Lu Bu or Fai. |
|---|
Draw Single-Target Attacks with Li
Rahkun's Basic Attack damage is quite high, and since your Stun Immunity can sometimes be stripped by the buff duration reduction on his Basic Attacks, it's recommended to have Li draw attacks with his Taunt and Physical Attack Reduction, after equipping him with Orchestrator gear to boost his Effect Resistance is recommended.
To ensure he can use his skills repeatedly, make Li's Speed the slowest in the party, and pair him with Velika, who should be the fastest.
Overpower them with Physical Team's DPS

|---|---|---|
Floor 18 | | |
On Floor 18, the boss gains a 30-hit Damage Immunity when he uses Skill 2. Quickly remove it by focusing on Bai Jiao's Poison and Bleed, then use a damage-boosted Pascal with buffs/debuffs to deplete his HP all at once.

On 20F, Attack Based on Kris's HP
| Floor | Enemy Team | Best Team |
|---|---|---|
| Floor 20 | | |
On Floor 20, Kris has Physical Attack Reduction if his HP is 50% or more, and Magical Attack Reduction if it is below 50%. After defeating everyone except Kris with physical attacker Kyle and healer/magic attacker Sun Wukong, switch your attacks based on Kris's HP.
Counter Death with Debuff Removal
Silence Immunity is effective, but Death Immunity cannot be used because of the Death Immunity nullification rule. Therefore, if Death is applied, counter it with debuff removal from heroes like Elysia.
Remove Immortality with Buff Removal or Reduction
All enemies will revive once with Immortality. Since the Skuds' duration is 3 turns, Elysia's buff duration reduction is sufficient, but since Kris's duration is 10 turns, you should remove it with buff removal from Biscuit or Kyle.

What is the Tower of Trials?
Clear Floors to Collect Medals and Rewards
The Tower of Trials is a PvE content where you can earn rewards such as Rubies and Hero Summon cards based on the number of medals you obtain. You get medals by defeating all enemies on a floor, allowing you to proceed to the next one.
| Tips! | To challenge the Tower of Trials, you must first clear up to floor 100 of the Infinite Tower. The Tower of Trials has 20 floors. |
|---|
One Season is 4 Weeks Long
The Tower of Trials is season-based, with each season lasting four weeks. When a new season starts, there will be changes to some enemy placements and medal acquisition conditions.
Conquering the Tower of Trials Tips
Additional Rules: Number of Obtained Medals Change
In the Tower of Trials, you can apply additional rules. Applying buff rules to strengthen allies makes it easier to clear, but you will get fewer medals. Conversely, applying debuff rules makes it harder to clear, but you will get more medals.
Aim to Clear First
You can re-challenge floors you have already cleared in the Tower of Trials. While it's best to collect all 6 medals from the start, it's also okay to aim for a full clear first and then come back to collect the remaining medals later.
Even-Numbered Floors Require Countermeasures
Generally, odd-numbered floors are relatively easy to clear, even with your standard PvP party. However, for even-numbered floors with bosses, you often won't be able to clear them without building a specific counterparty based on strategy guides in many cases.
Orchestrator Equipment and Debuff Removal Are Useful
Some floors have additional rules that can incapacitate you with effects like Petrify. When these rules are active, you will need to remove the status effects by using heroes with the corresponding status effect Damage Immunity, or with Debuff Removal skills like Elysia equipped with Orchestrator gear.
| Tips! | With the 4-Set Effect (Crowd Control Immunity) of Orchestrator equipment, you can avoid initial status effects. |
|---|
HP Alteration and Death Do Not Work
In the Tower of Trials, HP Alteration does not work, so heroes with HP Alteration skills like Freyja are less effective. Similarly, Death effects also don't work, making Death-focused parties unsuitable for the Tower of Trials.
Use Other Players' Clear Information as a Reference
In the Tower of Trials, you can view other players' clear party information from the Clear Info button in the bottom left of the party formation screen. If you're stuck on team composition, copying a team from the Clear Info is a viable option.

Best Heroes to Train for the Tower of Trials

Velika's Cooldown Reduction on Basic Attack is Powerful
Velika can reduce the cooldowns of all allies with her Basic Attack only in the Infinite Tower and Tower of Trials, making her often a key hero for conquering the Tower of Trials. She is one of the heroes you'll definitely want to train for this content.
Velika - Rating & SkillsBarrier-Generating Heroes
| Hero | When to Use |
|---|---|
 Daisy | When you want Magic Attack Boost, Buff Removal support, and Barrier generation at the same time(requires T2) |
 Evan | When you want to increase durability with a Barrier + Defense Boost passive. |
 Asura | When you want to generate Barriers or apply Focus Target repeatedly. |
In the Tower of Trials, there are often floors where HP management with Barriers is essential. Heroes like Asura, who has a short cooldown on her Barrier generation, have their own strengths, so build your team according to the floor's characteristics.
AoE Healing Heroes
| Hero | When to Use |
|---|---|
 Lina | When you want a healer who can also boost the damage of your attackers. |
 Alice | When you want a healer who can increase the team's overall durability. |
 Sun Wukong | When you want a hero who is both an attacker and a healer, or when you want to reduce the enemy's Damage Nullification count. |
 Yui | When you want to recover with an ally Revive, or when you need Burn Immunity. |
 Lucy | When you need Debuff Removal. |
Battles in the Tower of Trials can often be prolonged, and many floors require a healer. Lina is generally recommended, but if you're using two healers or need to counter specific gimmicks, other healers may be necessary.
Single-Target Focused Attackers
| Hero | When to Use |
|---|---|
 Shane | When Physical attacks are effective, or when using Rachel to reduce enemy damage output. |
 Pascal | When Magic attacks are effective, or when using Daisy for Barrier generation /Lucy as a healer. |
 Bai Long | Use Bai Long for multiple Physical Single attacks. |
 Xiao Qiao | Use Xiao Qiao for multiple Magic Single Attacks or Increase Pascal's DPS. |
The Tower of Trials features many single bosses, so single-target attacks are often effective. Shane is recommended if Physical is effective, and Pascal if Magic is effective. Sometimes the choice depends on synergy with other heroes you're using to counter gimmicks.
Status Effect Immunity Heroes
| Hero | When to Use |
|---|---|
 Chloe | When you need Shock Immunity, Unable to Recover, or a Crit Rate Boost. |
 Feng Yan | When you need Freeze Immunity. |
 Leo | When you need Death Immunity. |
 Jin | When you need Silence Immunity. |
 Cleo | When you need Silence Immunity or when Poison is effective (Raising Speed is effective in the fight against Dellons) |
Countermeasures for status effects may be necessary on certain floors. Cleo is particularly useful in the Dellons' fight for her Silence Immunity and her ability to reduce the Damage Nullification count with Poison. Chloe is also sometimes used for her Unable to Recover or Crit Rate Boost.
Versatile Support Heroes
| Hero | When to Use |
|---|---|
 Biscuit | When you want to increase damage dealt to bosses. |
 Elysia | When Debuff Removal is needed. |
 Rachel | When you want to reduce the enemy's damage output/durability, or when you want to boost Shane's damage. |
Biscuit is used on most even-numbered floors with bosses. Elysia is useful for removing initial status effects like Petrify from additional rules, and Orchestrator gear is recommended for her. Rachel is also an easy-to-use hero when you need debuffs.
Other Heroes Needed for Specific Floors
| Hero | When to Use |
|---|---|
 Bai Jiao | When the enemy has high durability and Poison or Bleed is effective, or when you want to quickly reduce the Damage Nullification count. |
 Li | When you want to draw single-target Physical attacks with Taunt x Physical Damage Immunity. |
 Joker | When you want to quickly reduce the Damage Nullification count. |
Depending on the gimmicks of each floor, other specific heroes may be necessary. In particular, the gimmick-countering heroes most often needed in the Tower of Trials are Bai Jiao, Li, and Joker. Be sure to train these heroes as well.
