Infinite Tower 70F Recommended Heroes

Death Immunity / Buff Duration Reduction

Death Immunity (Only One)
Leo
Buff Duration Reduction (At Least One)
Teo	Nia	Elysia	Miho

To counter Knox's Death skill, you can use Leo for Death Immunity. Alternatively, since Death requires at least two stacks to activate, you may use heroes with Buff Duration Reduction to remove the first stack before Knox applies the second one.

Silence Immunity

Choose One
Jin	Cleo

Bane has a skill that inflicts Silence on all of your heroes. To counter this, include a hero who provides Silence Immunity. Both Jin and Cleo are good options. Aside from Silence Immunity, Jin offers reliable Stun, and Cleo provides Attack Reduction and Poison to help control the battle.

Poison Immunity

Only One
Lucy

Lucy is the only hero with Poison Immunity, making her the direct counter to Cleo's Poison. At 6th Transcendence, she also provides Cooldown Reduction to back-row Magic heroes.

Petrify Immunity

Choose One
Daisy	Black Rose

Cleo inflicts Petrify, which can immobilize your team for two turns. To counter this, bring a hero with Petrify Immunity. Daisy and Black Rose are both solid options. Choose Daisy if your main DPS is Magic-type, and Black Rose if your DPS is Physical-type.

Bleed Immunity

Only One
Karon

Leo inflicts Bleed, which can deal moderate damage if left unchecked. Karon is the only hero with Bleed Immunity, and his healing abilities further enhance your team's survivability.

Crowd Control

Choose One
Yu Shin	Eileene	Kagura	Mercure

Crowd Control heroes are effective counters against enemies with status/debuff skills. This strategy provides more team flexibility and helps minimize damage taken.

Versatile Supporters

At Least One
Biscuit	Lina	Vanessa	Ace
Rachel	Yui	Evan

Biscuit 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 or Ace for Defense Debuffs, and Yui or Evan for healing and durability.

Damage Dealer (DPS)

At Least One
Teo	Yeonhee	Klahan	Kyle

Choosing heroes with strong AoE DPS skills is always a solid choice. Teo and Yeonhee can easily clear Infinite Tower 70F, while Kyle and Klahan are also reliable alternatives if you don't have them.

Infinite Tower 70F Team Example

Physical Team

Front Row	Front Row	Front Row	Front Row	Back Row
Evan Tank	Yui Lina Karon Healer	Elysia Buff Duration Reduction Eileene Crowd Control	Biscuit Miho Def Debuffer (Flex Slot)	Teo Kyle Main DPS

You can counter Knox with Buff Duration Reduction. Death activates at two stacks, and since only Knox can apply it, you can remove the first stack before he inflicts the second. Teo is an effective Main DPS with Buff Duration Reduction, but if he’s unavailable, you can use Elysia or Miho for the Flex Slot instead.

Magic Team

Front Row	Front Row	Front Row	Front Row	Back Row
Lina Yui Karon Healer	Mercure Magic Flux (Flex Slot)	Vanessa Biscuit Debuffer (Flex Slot)	Yu Shin Crowd Control (Flex Slot)	Yeonhee Main DPS

If the lineup remains unstable, slot in a Hero with Buff Duration Reduction in the Flex position to mitigate Death and other multi-turn debuffs. Recommended units for this role include Miho, Elysia, and Nia.

F2P Team

Front Row	Front Row	Front Row	Front Row	Back Row
Evan Tank Miho Buff Duration Reduction	Jin Silence Immunity Daisy Petrify Immunity Lucy Poison Immunity (Flex Slot)	Yui Healer Karon Healer Bleed Immunity	Eileene Crowd Control Leo Death Immunity (Flex Slot)	Kyle Main DPS

If your team doesn't include any heroes with Immunity, add Heroes with Buff Duration Reduction to mitigate Death and other multi-turn debuffs.

If you find it difficult to clear, consider investing in and substituting heroes with Immunity, or use the recommended characters listed in the team compositions above.

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.

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 70F. 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.
