Dellons is also present and contributes additional pressure by inflicting Silence.

Infinite Tower 80F Recommended Heroes
Immunities
| At Least One per Immunity | |||
|---|---|---|---|
| JinCleo Silence Immunity | DaisyBlack Rose Petrify Immunity | Chloe Shock Immunity | Victoria Paralysis Immunity |
Select a hero with the appropriate Immunity to complement your lineup. Ideally, choose Heroes that contribute to damage output against enemy units that rely on Crowd Control.
 Tips! | If you have Yu Shin and a strong CC Hero, you may skip immunity heroes as long as your Crowd Control is reliable enough. |
|---|
Crowd Control
Crowd Control heroes are effective counters against enemies with status/debuff skills. This strategy provides more team flexibility and helps minimize damage taken.
| Tips! | Adding Yu Shin is highly recommended due to his Increased Effect Hit Rate for all allies and inflicts Paralysis/Effect Resist Reduction. |

Versatile Supporters
Biscuit
Lina
VanessaBiscuit and Lina are highly versatile supporters who can be used on any floor of the Infinite Tower. Lina's Effect Resist Boost is especially useful against enemies with strong crowd control. If you don't have them, you can use Vanessa for Defense Debuffs, and Yui or Evan for healing and durability.
Damage Dealer (DPS)
| At Least One | |||
|---|---|---|---|
| Teo | Klahan | Kyle | |
| Freyja | Branze & Bransel | - | - |
Choosing heroes with strong Physical AoE DPS skills is always a solid choice. Klahan can easily clear Infinite Tower 80F, while Kyle and Teo are also reliable alternatives if you don't have Klahan.
Infinite Tower 80F Team Example
Pierce & 2 CC Team
| Front Row | Front Row | Front Row | Front Row | Back Row |
|---|---|---|---|---|
 Yui LinaHealer | Yu Shin Crowd Control | Kagura Crowd Control Debuffer (Flex Slot) | Teo Sub-DPS | KlahanKyle Main DPS |
Enemy units with Crowd Control have All Damage Immunity. To counter this, you will need DPS heroes with Pierce, as well as Crowd Control units to immobilize enemies before they can activate their own CC skills.
Teo Physical Team
| Front Row | Front Row | Front Row | Front Row | Back Row |
|---|---|---|---|---|
 EvanTank | LinaYui Healer | Eileene Crowd Control Yu ShinCrowd Control | Jave Crowd Control  RachelDebuffer (Flex Slot) | Teo Main DPS |
If you don't have other reliable CC units, you can use Rachel in the Flex Slot for her Weakness Hit Chance, which provides increased damage output.
| Tips! | If clearing the stage is still difficult, consider investing in and substituting heroes with the appropriate Immunities, or use the recommended characters listed in the team compositions above. |

Strategy & Tips
Crowd Control is Effective
Instead of reducing enemy healing, you can bring heroes with AoE Crowd Control to stop them from healing entirely. This strategy provides more team flexibility and helps minimize damage taken.
Use Protective Formation
Protective Formation is the recommended setup for Infinite Tower 80F. 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 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. |
|---|
Use 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 'Barrier', then use priority skills manually to gain the upper hand. |
|---|
Enhance Your Hero
Enhance your heroes' skills, ultimate, and power-up to +5. Prioritizing tanks and healers to boost their effectiveness and utility. Skill & Ultimate Enhancement materials can be obtained from Story Event rewards, the Shop, and the Infinite Tower.
