How to Beat ［Attendant Tainted in Black］ Iris Overview

Tainted Iris is a tanky, hard-hitting witch that can protect your main attacker while debuffing the enemy team's ATK. Fighting against a team that has her will see your party weakened as they try to break through her defenses, which would then open your party up to be destroyed in detail by the enemy's main attacker.

	Level 2 (Unlocks by level 21) Additionally, before dealing the physical attacks, if a target is afflicted with ［Decreased ATK］, the physical attack’s damage to that target is multiplied by 2.

Defensive Buffs for Herself and Her Allies

Outpouring Feelings

Indomitable Spirit

Skill	Skill Effect
Outpouring Feelings	Level 1 (Unlocks by level 41) At the start of the battle, this skill grants ［Force Field］ to Iris for 2 turns. If a character enhanced with ［Force Field］ is attacked and takes damage that exceeds 20% of their max HP, the exceeding amount of damage is cut by 50%.
	Level 2 (Unlocks by level 121) Additionally grants ［Force Field］ to the ally with the highest ATK other than Iris for 2 turns.
	Level 3 (Unlocks by level 201) Additionally grants［Force Field］ to the ally with the highest SPD other than Iris for 2 turns. If this ally target is the same as the ally target with the highest ATK, these 2 buffs will overlap, causing this skill's ［Force Field］ to be overwritten by the new ［Force Field］. Thus, ［Force Field］ will only be granted to Iris and this ally target.

Skill	Skill Effect
Indomitable Spirit	Level 1 (Unlocks by level 61) If Iris is attacked, and her remaining HP percentage becomes 30% or lower, this skill grants her ［Shield］ equal to 50% of her ATK for 2 turns (cannot be dispelled). This skill activates only 1 time per battle.
	Level 2 (Unlocks by level 141) Additionally, the size of ［Shield］ is further increased by 50% of Iris' ATK for each enemy who is alive when this skill activates (total size of 300% max).
	Level 3 (Unlocks by level 221) The number of turns of ［Shield］ becomes 3.

The second half of Tainted Iris' defensive strategy is to first grant herself and her allies with Force Fields that cuts by half the damage they receive if it exceeds 20% of their max HP. This covers both the team's main attacker as well as its fastest unit (if these are both only one unit, then the newest force field will overwrite the older one).

Tainted Iris' second passive meanwhile makes sure she stays alive throughout the fight by granting her a Shield that gets tankier the more enemies are still alive. This shield lasts for 3 turns and triggers once her HP becomes 30% or lower.

Witches to Beat ［Attendant Tainted in Black］ Iris

［Attendant Tainted in Black］ Iris Hard Counters

Nina

Aside from having high EVD that can dodge Iris' attacks as well as being relatively tanky to boot, Nina can also steal the Force Field Iris gives if she hasn't broken it already.

Florence

Florence, and other attackers that can do more than 2 attacks with their skills, can also take down Tainted Iris or at least the witch she is protecting by hitting them more than once. Tainted Iris' damage cut only triggers for the first attack, and it won't be there anymore for subsequent attacks.

［Attendant Tainted in Black］ Iris General Counters

［Attendant Tainted in Black］ Iris Sample Counter Teams

Nina Counter Team

Florence is the main damage dealer in this team, while Nina will go and steal Iris' Force Field. Once that's been done, Florence can overwhelm the enemy team with her multiple attacks fueled by Merlyn's CRIT buff. Dian is there to give EVD support to either Florence or Nina, while Soltina is there to soak up any damage that may come the team's way.

Witches Not To Use Against ［Attendant Tainted in Black］ Iris

Cordie

Just like with other witches that grant shields, Cordie will have a tough time penetrating Iris' shield because of her low hit count. Even if she does manage to break it, the damage cut from Iris' Force Field can easily blunt the damage of even Cordie's most powerful nukes.

Lea

Lea's single-hit attacks can all be blunted or even blocked entirely by Tainted Iris' Force Field, leaving her vulnerable to any counterattacks by the latter's team.

Mimi

Mimi's second skill, Feline Waltz, only deals one hit which can be blunted by Iris' Force Field. Iris can also be buffed to have high DEF and be bait for Mimi's Resonance.

Tips for Beating ［Attendant Tainted in Black］ Iris

Bring Your Buff Dispellers/Buff Stealers

Witches like Nina, who can steal buffs, and other witches who can dispel enemy buffs are good to bring in a fight against Tainted Iris. At the very least, dispelling the buff would make the fight much easier.

Use Multi-Hit Witches

If you fail to get rid of Iris' Force Field, overwhelming her team with attacks could also do the trick. Multi-hit nukers like Florence, when sufficiently buffed, can definitely wipe the floor with the enemy team even with Taiinted Iris in there.
