Best Characters for Shadow Teo

Weaken the Enemy with Durability Debuffs

Highly Versatile Durability Debuffs
Lina	Biscuit	Vanessa	Reginleif
Orly	Ariel	Asura	Sylvia
Sarah
Magic Durability Debuffs
Melia	Xiao Qiao	Miho	Espada
Dongyoung (2 turns)	Vanessa (T6)	Skuld	Victoria
Highly Versatile Damage Buffs (Always Active)
Lina	Kagura	Miho
Magic Damage Buffs (Always Active)
Daisy	Orly	Kyrielle	Dongyoung
Yeonhee	Sung Jinwoo	O'Mok	Ariel

Shadow Teo uses a Buff Duration Reduction skill, so focus on debuffs rather than buffs at first to lower the enemy's durability. That said, damage buffs from always-active passive skills can still be used in the Teo fight.

Whittle Down HP with a Single-Target Magic DPS

Any 1+ of the Following
Espada	Pascal	Yuri	Daisy
Xiao Qiao

Once the field is set up, whittle down HP with your DPS. Shadow Teo reduces damage from physical and 2-5 target attack skills, so single-target magic attacks are effective. Pascal deals the most damage, with Xiao Qiao and Daisy as the next-best picks.

Manage HP with Healing and Barriers

Barrier-Granting Heroes
Evan	Rook	Asura	Daisy
Melia	Xiao Qiao	Xiao	Nezha

Healing Heroes
Lina	Orly	Sun Wukong

When your team's HP starts dropping, prioritize recovering with healing. If you're using Continuous Healing, it's best to use it right after Teo casts its Buff Duration Reduction skill.

Strip Immortality Revival with Buff Removal

Any One Hero
Vanessa	Chloe	Biscuit	Orly
Daisy	Silvesta

Shadow Teo revives via Immortality in Round 1, so strip it with Buff Removal right away and move on to Round 2. Daisy, who has a single-target magic attack based on max HP, along with Defense-reducing heroes like Vanessa and Biscuit, are especially good picks.

Round 2 Starts with Remaining Turns

If you defeat Shadow Teo in Round 1 within the 70-turn limit, Round 2 begins using the turns you have left over. The strategy is the same, but since you use a different team for each round, you'll need to prepare two teams with a similar approach.

Use Your Stronger Team in Round 1 Early On

The enemy's level is higher in Round 2, but use your stronger team in Round 1 and aim to clear Round 1 within the turn limit first.

Tips!	It's only once early Round 1 clears become possible with your sub team that you can further boost your score by using your stronger team in Round 2.

Progress Ultimate Enhancement and Transcendence

To clear Round 1, upgrades like Ultimate Enhancement, Transcendence, and Skill Enhancement are essential. In particular, prioritizing Ultimate Enhancement and Skill Enhancement for your DPS is the best way to significantly boost your damage.

Best Team Comps

Round 1 Team Comp

Team Comp - Formation: Defense

Vanessa

Lina

Pascal

Melia

Kyrielle

Debuff

Buff/Debuff

DPS
Damage Boost
Barrier

Debuff

Buff

Using Lina's Defense Reduction → Pascal's attack → Vanessa's Buff Removal, this team comp aims for a 16-turn clear. The Vanessa and Pascal slots are fixed, but the rest can be swapped for your preferred Buff/Debuff heroes.

Target Stats

Hero	Target Stats	Notes
	90%+	Nice to have
	15000+	Healing Boost
	90%+	Nice to have
	4000+	The higher, the better
	90%+
	200%+	The higher, the better
	~5000	The higher, the better
	0%	Skill 2 Crit Rate is 100% at 6th Transcendence
	250%+	The higher, the better
	~90%

The key to breaking through 16 turns is boosting Pascal's Weakness Hit Chance through gear so that Crit and Weakness Hit trigger at the same time. Having Dedicated Equipment for Damage Amplification makes it much easier to clear.

Best Equipment & Rings

Hero	Equipment	Ring (Refine)
Vanessa
Lina
Melia
Kyrielle
Pascal

For heroes other than the Healer, it's best to equip a Boss Ring. For Lina, it's also better to equip a Status Ailment Ring so she can chip away at the enemy's HP even a little.

Best Pets

Ideal	Alternative	Alternative	Low Rarity
Jeo	Yeonji	Igris	Sherry

For pets, using Jeo to aim for a quick clear is best. If you don't have Jeo, use Yeonji or the collab rare pet Igris as a substitute instead.

Alternate Heroes

Main	Alternate	Notes
	Xiao	Alternate for Buff/Debuff and Sustain Support
	Espada	Alternate for Magic Vulnerability Debuff
	Miho	Alternate for Magic Vulnerability Debuff
	Yeonhee	Alternate for Magic Damage Boost

As mentioned above, the 3 heroes other than Vanessa and Pascal can be swapped for other Buff/Debuff heroes depending on what you have. This is just one example, so experiment and look for a combination that lets you clear in 16 turns.

Open with your Buff/Debuff skills, then use Pascal's Skill 2 twice to whittle down Teo's HP. Once Immortality triggers, use Vanessa's Skill 1 to remove buffs and move on to Round 2.

Round 2 Team Comp

Team Comp Formation: Balanced

Biscuit

Xiao Qiao

Orly

Daisy

Miho

Buff/Debuff

Attacker
Buff/Debuff
Barrier

Buff/Debuff

Attacker
Damage Buff
Barrier

Buff/Debuff

This team comp uses Xiao Qiao and Daisy as the two attackers. Since Orly provides a Crit Rate buff, you can freely invest gear stats into Crit Damage, which is a nice advantage.

Target Stats

Hero	Target Stats	Notes
	100%	Increases Status Ailment Ring's proc rate
	15000~	Boosts Outgoing Healing
	4200~	Rank 3rd or lower in party Speed
	70%-80%	87%-97% with Orly's buff
	200%~	Higher is better
	50%~	Higher is better
	4500~	Rank 1st-2nd in party Speed
	70%-80%	87%-97% with Orly's buff
	250%~	Higher is better
	40%-50%	94%-100% with Biscuit's buff
	-	4th-5th recommended in party Speed
	4500~	Rank 1st-2nd in party Speed
	70%-80%	87%-97% with Orly's buff
	250%~	Higher is better
	40%-50%	94%-100% with Biscuit's buff
	-	4th-5th recommended in party Speed

We recommend lowering the Speed of main attackers Xiao Qiao and Daisy so they can stay buffed longer. Adjust them to act 4th-5th in turn order.

Best Equipment & Rings

Hero	Equipment	Ring (Refine)
Biscuit
Orly
Miho
Xiao Qiao
Daisy

For the support units, we recommend Biscuit and Orly equip a Status Ailment Ring. Boost damage output for the 3 attackers with a Boss Damage Ring.

Best Pets

Ideal	Alternative	Alternative	Low Rarity
Windy	Yeonji	Igris	Sherry

Windy, who can inflict Boss Vulnerability, is the best pet to use. If you don't have her, use Yeonji or the collab-exclusive rare pet Igris instead.

Alternate Heroes

Main	Alternate Hero	Notes
	Xiao	Alternate for the Buff/Debuff role

Xiao also works fine in Miho's slot. In that case, the basic skill order stays the same, but you'll need to use Orly's or Xiao's upper skill in between to consume a turn.

Biscuit's Turn 1 buff will get cut short quickly, but casting it here means its timing lines up well with the buffs during the second loop. Depending on your attackers' damage output, it's possible to clear the boss in under 70 turns.
