Overview of Nightmare 3-30
Difficult Without Proper Team Comp
Nightmare 3-30 is difficult to brute force, especially without a balanced team or sufficient gear. Relying solely on high offensive units will not guarantee victory. This stage heavily emphasizes and rewards proper team building, making the right tools and immunities essential for clearing it.
Requires 2 Teams
It’s important to note that Nightmare Mode requires players to set up two separate teams per stage. This means you’ll need to raise more heroes and carefully balance both teams to ensure consistent clears.
Enemy Info
In Nightmare 3-30, the main threats are Yuri in the first wave and Leo in the second. Yuri’s skills deal heavy damage and ignore defense, making it hard to survive without Taunt or strong gear, while Leo inflicts Bleed on the party, causing significant damage over time.

Taunt
| Recommended Hero | Details |
|---|---|
| Li | Li's Taunt skill grants two hits of Physical Damage Immunity.. Additionally, his passive lets him counterattack while healing based on his Max HP, and his HP Alteration skill can set an enemy’s HP to 28%, making him invaluable for tough encounters. Recommended Set: Gatekeeper |

Strategy & Tips
Bleed Immunity for Second Wave
If you’re struggling to survive the second wave, adding Karon to your team can greatly improve survivability by providing consistent healing and Bleed Immunity.
Li is Highly Recommended
Li offers a wide range of utility that greatly improves survivability in Nightmare 3-30. When timed correctly, his Taunt can absorb Yuri’s Ignore Defense skill, often determining whether an ally survives. He also counters and self-heals, further enhancing his durability in tough battles.
Crowd Control is Effective
Instead of taunting enemies, you can bring heroes with AoE Crowd Control to stop them from applying a 2 turn All Damage Immunity. This strategy provides more team flexibility and helps minimize damage taken. Additionally, enemies only have 11% Effect Resistance, so your heroes can focus more on survivability.
HP Alteration
Inflicting HP Alteration is an effective way to deal damage, as it sets enemies' HP to a fixed threshold, ignoring both their HP and defense. Platin stands out as a strong option for this role, serving as both a tank and a source of HP Alteration. This effect also ignores All Damage Immunity, allowing you to use this effect while the buff is active.
Death Teams
If you have Kris, running a Death Team is a strong alternative. This setup lets you bypass enemy mechanics and stats entirely by instantly defeating them after 3 turns or once 2 stacks of Death are applied.

Enhance 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 Nightmare 3-30. 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 investments into your characters and gear.
 Tips! | 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 investing in adding a weapon slot to your strongest 6★ Legendary DPS or an armor slot to other team members. Nightmare 3-30 is extremely difficult without Ultimate Enhancements, so make sure your core heroes are at least fully enhanced to maximize their survivability and damage output.
Ultimate Enhancement GuideRuby Farm for Fusion Fodder
Once 14-1 or Nightmare 1-1 becomes available, players should begin Ruby Farming to gather enough fodder for fully Ultimate Enhancing their team. This greatly improves survivability and makes clearing stages much easier.
Ruby Farming 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.
| Tips! | Strategically, queue buffs first, such as 'Shield', then use priority skills manually to gain the upper hand. |
