Adventure Level 10-30 Overview
Enemy Info

Knox is the main boss of Adventure 10-30. He can inflict Death, a curse that defeats the target after 3 turns. This effect can also trigger immediately if the target is hit by the Death skill again while the status is still active.
Sarah Appears on Round 2

Sarah joins Knox in the second round, which can be troublesome if you rely on debuffs since she has a skill that removes them. It’s highly recommended to defeat her first before applying debuffs to the other enemies.
Enemy List For Adventure 10-30
Adventure Level 10-30 Recommended Heroes
Crowd Control
Recommended Hero | Details |
---|---|
![]() ![]() | Both Yu Shin and Mercure are mage-type characters who excel at crowd control. Mercure can stun enemies, while Yu Shin can paralyze them, preventing enemies from taking action on their turn. |
![]() ![]() | If you’re focusing on physical damage dealers, Eileen and Kagura are excellent choices. Eileen’s Shock and Kagura’s Petrify can effectively immobilize opponents, keeping them locked down for a while. |
Damage Dealer (DPS)
Recommended Hero | Details |
---|---|
![]() | Most recommended DPS for this Adventure level. His skills deal high damage to all enemies, and with Immortality and All Damage Nullification, his survivability is high. Two Skill Enhancements are recommended but optional. |
![]() | Ace's skills are highly valuable in Adventure Mode. He inflicts Defense Reduction, Physical Vulnerability, Buff Duration Reduction, and Reduced Incoming Healing, creating opportunities for your team to deal higher damage and complete the run faster. |
![]() | She grants all allies a Weakness Hit Chance Boost and inflicts Defense Reduction and Physical Vulnerability on 3 targets. While one of her skills targets only a single enemy, her self-revive greatly enhances her survivability. |
![]() | Optionally, if you don't have a Legendary sub-DPS, Rei is a solid choice. Her skills hit all enemies and can inflict Poison and Bleed, while her Physical Attack Boost increases her own damage output. |
Immunities
Recommended Hero | Details |
---|---|
![]() | Evan has a skill called “Stun Immunity”, which prevents him from being stunned by enemies. Since the enemies in 10-30 also use stun skills, adding Evan to your team helps reduce the risk of your party being immobilized. |
![]() | Leo is the only character with Death Immunity, making him an excellent matchup against Knox. With proper healer support, he can serve as a strong attacker while inflicting Defense Reduction during the fight. |
Healers & Supporters
Recommended Hero | Details |
---|---|
![]() | Lucy is the best-suited healer for this fight, as she not only provides strong healing but also has a higher Debuff Removal count compared to other characters with the same skill. |
![]() | Yui is the top recommended support for Adventure stages. She provides continuous healing, greatly boosting team survivability. Enhancing her healing skill for an extra turn is highly recommended. |
![]() | Lina provides a Damage Boost and Continuous Healing. Paired with Yui, they ensure consistent team healing throughout the battle. Lina doesn't require any Skill Enhancement. |
![]() | Karin is a versatile healer and debuff remover. She has the shortest skill cooldown among the healers listed here, making her a great choice if you’re looking for a reliable and easily accessible healer for your party. |
Adventure Level 10-30 Team Formation Example
Crowd Control Party (Balanced Formation)
Front | Front | Front | Back | Back |
---|---|---|---|---|
![]() ![]() Tank | ![]() ![]() Healer Buffer | ![]() ![]() Debuff Removal | ![]() ![]() Crowd Control Damage Dealer | ![]() ![]() Crowd Control Damage Dealer |
The first team formation is a balanced setup, placing crowd control damage dealers in the backline to maximize damage while avoiding enemy aggro. We chose Yu Shin/Mercure for Magical damage and Eileen/Kagura for Physical damage.
DPS Party (Protective Formation)
Front | Front | Front | Front | Back |
---|---|---|---|---|
![]() ![]() Tank | ![]() ![]() Healer Buffer | ![]() ![]() Debuff Removal | ![]() ![]() DPS Debuffer | ![]() ![]() Crowd Control DPS |
For the DPS Party, Teo or Kagura are best suited for the back line in Protective Formation. They’re strong attackers, and the formation’s boost further enhances their damage. Ace or Rachel can be added as backup attackers to help take down enemies more quickly.
F2P Team (Protective Formation)
Front | Front | Front | Front | Back |
---|---|---|---|---|
![]() Tank | ![]() Healer | ![]() ![]() Debuff Removal | ![]() DEF Debuff Second Attacker | ![]() Physical Attack Main Attacker |
For this team, we chose Rei as the Main Attacker due to her high attack power for a Rare character. She also has skills that inflict continuous damage, such as Bleed and Poison, which steadily chip away enemy HP. Since she’s a Rare Character she’s easier to obtain and can be Transcended more easily.
Adventure Level 10-30 Strategy & Tips
Bring Healers or Characters with Debuff Removal

Since the enemies can inflict debuffs on your characters, it’s best to include someone in your party who can cleanse them. We recommend adding Lucy, as she can remove up to three debuffs from allies. Alternatively, Karin is a great option if you want a healer who can also remove debuffs.
Rank Up Characters If Possible

One effective way to progress through tougher stages is by ranking up your characters. This boosts their stats and increases their star level, making it essential for clearing high-difficulty quests.

Transcendence provides an additional stat boost for your characters. If you have two or more copies of the same character, make sure to use them to transcend and gain these extra stats.
Transcendence GuideTranscend Also Unlocks Additional Skill Effects

In addition to boosting character stats, certain skill effects are unlocked at specific transcendence levels. This can give your party a valuable advantage, especially if you don’t have many Legendary characters.
Ultimate Enhancement To Equip More

Having two pieces of equipment is always better than one. By using Ultimate Enhancement, you can increase your main party’s equipment slots, making it easier to clear not just Adventure 10-30 but other challenging stages as well.
Ultimate Enhancement GuideUpgrade Equipment Fox Max Power

Equipment plays a crucial role in your character’s growth, as it boosts stats based on the type of gear equipped. Upgrading your equipment further strengthens your characters, giving you an advantage in battles. Utilize this to your advantage against formidable enemies.
Equipment Power Up GuideEnhance Hero Skills

Enhance your heroes' skills, prioritizing tanks and healers to boost their effectiveness and utility. Skill Enhancement materials can be obtained from Story Event rewards, the Shop, and the Infinite Tower.
Skill Enhancement GuideUse Protective Formation

Protective Formation is the recommended setup for Adventure Modes. At Level 20, it boosts Back Row heroes' Attack by 26% and grants Front Row supports and healers a 6.5% Defense increase. Other formations can also work, but require more investment into your characters.
![]() | Make sure to enhance the formation level for increased back row and front row effect. The higher the Formation level, the better. |

Ultimate Enhance Your Team

If you have an Ultimate Enhancement Material, Leah, or spare Fusion fodder, it’s worth using them to add a weapon slot to your strongest 6★ Legendary DPS or an armor slot to other team members. While Adventure 14-30 is still manageable without them, your team may struggle to stay alive without sufficient Ultimate Enhancements.
Ultimate Enhancement GuideUse Skill Queue

Auto Skills offer convenience, but they don't always select the optimal skills in critical situations. It's best to use the Skill Queue to start with a buff, then monitor combat and manually activate skills as needed.
![]() | Strategically, queue buffs first, such as 'Shield', then use priority skills manually to gain the upper hand. |
