The Heretical Ruins stages will test your team damage output capabilities. If you fail to make quick work of enemy minions or bosses, the situation on the battlefield can spiral into a difficult scenario as the boss keeps stacking and raising their damage. In this article, we'll walk you through the more easily accessible rare/epic hero lineups, aiming at guiding you to clear the stage on difficulty #9. Meanwhile, we'll give you a legendary hero lineup for reference, which you can use for efficient auto-combat.
I. About The Boss

II. Stage Clearing Configuration [Recommended Level and Equipment] ● Recommended Level It is recommended that you try this when the overall level of your team goes over 90. ● Equipment Requirements This stage requires you to have high damage output and the ability to tank damage. You should do your best to give legendary gear at max Refinements (+20) to your DPS heroes. Support heroes can meet the standard with fully refined (+16) epic gear. If you have mythic equipment with the right attributes, such as Tunnel King's Cloak, Precise Carnage Gauntlets, or Moonlight Battle Robes, it's highly recommended to equip them for this stage. Key Attribute Reference 1. Ideally, the average HP of your heroes should be over 30,000. 2. Your main tank should have over 65,000 HP and over 2,000 DEF. 3. Heroes responsible for applying debuffs or control effects should have more than 220 Accuracy; III. Recommended Lineups Lineup 1 Lineup: Nathaniel+Thia+Iola+Nimbus+Vani Positioning Reference:

Description: With Season 3's Necrosis and Ice Elemental Affinity as the core, this team has Nathaniel as its tank, thus requiring survivability attributes. We recommended you equip Puppeteer Revelation and stack DEF to also enhance nearby teammates' survivability. In this lineup, Nathaniel, Thia, and Vani can provide buffs to teammates, triggering Nimbus' passive skill to increase damage output. Also, when a buff expires, you can trigger Nathaniel's passive skill for healing; All these heroes are ranged, so Thia's ultimate skill can provide the entire team with Invisibility and Immunity to debuffs, reducing incoming damage thanks to Thia's passive skill, and all can benefit from Thia's battle skill's healing. Iola can inflict Attack Penalty and Control effects to disrupt enemy minions from using skills. Nimbus and Vani are two high-quality, easily-obtainable ranged damage dealers for this Elemental Affinity. If you replace them with higher quality heroes of the same type, such as Tharivol and Ivellios or Ozul and Daphne, you can clear stages even faster. Lineup 2 Lineup: Garius+Catherine+Dane+Theohein+Careth Positioning Reference:

Description: With Season 3's Radiance and Fire Elemental Affinity as the core, this team ensures that all members are within Catherine's healing range. Garius and Catherine can provide ample AoE healing, but you'll have to make sure that your heroes have the Debuff Immunity from Catherine's ultimate skill before the boss uses their fourth skill. Dane can apply Healing Prohibition when the boss's HP is below half. It's best that you use Dane's ultimate skill before the boss's fourth skill because this will remove the boss's buffs and inflict Attack Penalty to reduce their AoE damage. Theohein and Careth are two very great epic damage dealers for the Aura faction, capable of quickly eliminating the Phoenix Eggs with their powerful AoE attacks to prevent the boss from accumulating their Total Damage Bonus. Lineup 3 Lineup: Frurbath+Gareth+Vicuc+Rowena+Rava Positioning Reference:

Description: With Season 3's Poison and Ice Elemental Affinity as the core, this lineup demands you to have a well-developed Frurbath. Frurbath, as the tank, bears most of the boss's damage and provides AoE healing over time for teammates. With the help of Gareth's ultimate skill, you can keep the enemies consistently under Attack Penalty; Vicuc should use his ultimate skill immediately after the boss uses their fourth skill to dispel Burn and provide some healing for allies. Rava can inflict Frost on enemies. With her ultimate skill causing multiple damage instances over a large area, it's very suitable to wear Witch's Remnants to apply Defense Penalty to the enemy, thus aiding Rowena in dealing high damage. IV. Examples *Using Lineup 1 as an example.

● Team Aura Here, Nimbus's Attack Aura is selected to increase damage output, as the Phoenix Eggs after Nirvana permanently grant the boss a stackable Total Damage Bonus, it's advised to maximize damage output so you can quickly clear early-game stages. ● Equipment

Description: When Vani is equipped with Dawn Pipe Organ, it's crucial to stack Attack and Skill Haste using equipment as much as possible. ● Food Improvement When your team is not fully fledged, your heroes will have trouble surviving and dealing damage, so we recommend you use [Aquitaine Meat Pie], which is made of Elf Wheat ×2 and Wild Boar Meat ×1. It can give you +10% HP and +5% ATK for 600 seconds. ● Stage Clearing Tips 1. After the boss uses their third skill, use Iola's ultimate skill on both the boss and their minions to apply an Attack Penalty. 2. Since Iola's ultimate skill causes damage three times, it can easily trigger the Witch's Residue or the Unclean Crown's Artifact effect, applying a Defense Penalty to enemies. Once the enemies are inflicted with Defense Penalty, you can then use Nimbus's ultimate skill to boost damage output. 3. Thia needs to ensure that, by the time the boss uses their fourth skill, all allies have the Debuff Immunity provided by her ultimate skill. Additionally, try to apply Healing Prohibition to the boss before minions use their skills. 4. Taking turns to use the ultimate skills of Nathaniel and Iola will suffice because this will reduce incoming damage throughout the fight. 6. Given Vani's low base HP and DEF, it's recommended to choose equipment stats that boost HP% or DEF% to ensure survival. 7. When you are about to lose allies, use the Control Skill to grant shields to all allies. ● About Auto-Combat Skill Timing:
 Description: If your heroes are well-developed, this lineup can also be used for auto-combat. However, since Vani is more likely to perish when equipped with offensive gear, it's necessary to equip her with items that grant HP or DEF to allow more room for errors in auto-combat. The timings for using skills are for reference only, and you should adjusting them according to your heroes' skill level and Skill Haste.
 V. High-end Auto-combat Lineup Rec

Recommended Lineup Lineup: Nathaniel + Thia + Iola + Ozul + Daphne Positioning Reference:

● Team Aura Here, Daphne uses an Attack Aura, which can increase the ATK of all your heroes by up to 45% in this stage, allowing you to clear it a lot faster. ● Sample Lineup This lineup is an advanced version of lineup 1 for clearing early-game stages, with Daphne possessing Ozul to provide him with a significant amount of Shadow Energy as well as offensive and survival buffs. With Daphne's buffs, Ozul, upon using his ultimate skill and entering Demon form, can deal high AoE damage over time. In this lineup, Ozul can clear the entire dungeon during a single Demon form instance after using his ultimate skill. It's worth mentioning that Ozul is a ranged damage dealer, who, even after transforming into Demon form, still benefits from the ATK boost provided by the Dawn Pipe Organ and the Invisibility effect from Thia. ● Skill Timing Given the ample output from Ozul and Daphne, battles usually end quickly, so no special configurations are needed. If the damage dealers are not well-developed enough, which can lead to prolonged battles, you can refer to the early-game stage-clearing examples previously mentioned and let three support heroes take turns to use their ultimate skills to enhance the team's survivability.

[Configurations] ● Recommended Level It's recommended to prioritize leveling up Ozul after the team reaches level 90 and a breakthrough. ● Key Attributes Nathaniel's DEF > 2,500. All of the deployed heroes should have over 35,000 HP and over 1,500 DEF. Thia and Iola's Accuracy > 220. ● Equipment Description: If the damage dealers are not well-developed enough, it's even more recommended to equip Thia with the Rift Hourglass to use skills more frequently.
