Ibuki-Douji (Berserker)'s Strengths

AoE Berserker with 50% NP Charge

Ibuki-Douji (Berserker) is an AoE Arts Berserker with a 50% NP charge. She is a highly versatile attacker who can deal 1.5x damage to almost all classes and has a wide range of choices for Craft Essences and supports.

High Damage Potential with Noble Phantasm Effect

Her Noble Phantasm deals Special Attack damage to "Earth Attribute" enemies, with the multiplier increasing via Overcharge (OC). Since the Earth attribute is common among both Servants and regular enemies, there are many situations where she can dish out high damage.

Capable of 3-Turn NP Looping (System)

Because her NP hits allow for a decent amount of NP refund, she can achieve a 3-turn NP loop even with a 0% NP Start CE when supported by Altria Caster. She is an excellent system attacker who can even loop against Berserker enemies depending on the amount of Overkill.

Tips	Her NP efficiency isn't "top-tier," but it is more than enough for practical use. Against classes like Berserkers where NP gain is difficult, looping might fail depending on enemy HP.

Maximum Skill Usage (Button Presses)

While not exactly a weakness, Ibuki-Douji (Berserker) uses all three of her skills for farming, which maximizes the number of button presses. Additionally, Skill 2 requires you to select a target (herself), which adds to the click count.

Tips	Since using a System setup inherently involves many skill uses, I don't think it's a point worth worrying about too much.

Top-Class ATK Stats

She boasts top-class ATK among all Berserkers. Since ATK is the foundation for all damage, her overall output for Noble Phantasms and Critical Hits is exceptionally high.

Capable of Supporting Ally Damage

She possesses an ATK Up buff for the whole party and a targetable Buster/Arts buff. While the BA buff is typically used to boost her own NP damage, it can also be used to support an ally if your damage output is already sufficient.

NP Gain Support for Summer Servants & Spiritron Dresses

Skill 1 includes an NP Gain Up effect for "Summer Mode" Servants. Summer Mode refers to Summer Servants and Servants with Summer Event Spiritron Dresses. While she usually focuses on her own NP looping, she can also help allies loop theirs.

Easy to Land Critical Hits

Skill 3 provides 10 critical stars every turn and a high-magnitude Star Absorption buff. The absorption rate is so high that she can easily land crits even with a small number of stars. With her own Critical Damage Up buff, she can dish out significant damage.

Tips	One thing to note for critical farming is that because the stars are gained "every turn," you won't have stars from this skill on Turn 1.

Excellent Pre-Damage Buff Removal on NP

Her Noble Phantasm triggers "Defensive Buff Removal" before damage, allowing her to strip away Invincibility or Evasion before hitting the enemy. This makes her very easy to use in high-difficulty quests where enemies often have annoying defenses.

Leave Defense to the Supporters

She has almost no defensive or survival skills, so you must protect her using supporters. Fortunately, Arts supporters like Altria Caster and Lady Avalon are excellent defensive units, so this rarely becomes a true drawback in a team.

Tips	Leave the protection to your allies and just focus on going all-out! That's the kind of Servant she is.

Skill Cooldown Reduction via Skill 2

Skill 2 also has a 1-turn Skill Cooldown reduction effect that can be granted to a single ally. While hard to utilize in farming, it reduces her effective cooldowns to just 5 turns in high-difficulty content. Since most of her buffs last 3 turns, she has very little "downtime."

Tips	Of course, you can also use it on allies to help them get their defensive skills ready in time or increase the rotation speed of powerful abilities!

Servants with Good Synergy

Compatible Attackers
	Morgan (★5) A Berserker with a 50% NP Charge. She provides a party-wide ATK buff and offensive support to other party members. Her NP increases Overcharge, which in turn boosts Ibuki-Douji (Berserker)'s Special Damage Multiplier.
	Ibuki-Douji (Berserker) (★5) In a Double Support setup, she provides a 40% ATK Up, 60% Critical Strength Up, and 60% NP Gain Up, and generates 20 critical stars every turn.
	Archetype: EARTH (★5) She reduces cooldowns in a Buster System and provides offensive support, increasing the stability of clearing Wave 1.
	Ashiya Douman (★5) With up to an 80% NP Charge, his NP is easy to use. He is also easy to field due to his class advantage against many enemies. Since Ibuki-Douji (Berserker) has the Chaotic Attribute, she benefits from his ATK and Critical Strength buffs, making him a compatible offensive support.
Compatible Supporters
	Altria Caster (★5) She provides a high-multiplier Arts buff, up to a 50% NP battery, and an NP Gain buff, allowing her to effectively support NP looping. Furthermore, her Noble Phantasm provides a countermeasure against enemy NPs alongside an offensive boost, making her an exceptional match for both farming setups and high-difficulty content.
	Lady Avalon (★5) She provides a high-multiplier Arts buff and a 20% NP battery, making her a great support option for Arts looping systems. In high-difficulty content, her extensive HP recovery and party-wide Invincibility offer superb defensive utility, while her high-multiplier Critical Strength buff and passive star generation from her Noble Phantasm make it easy to deal heavy damage through critical hits.
	Tamamo-no-Mae (★5) She boosts damage output with a high-multiplier Arts buff and an NP Damage buff, making her a great support option for looping systems. Furthermore, her Noble Phantasm (NP) provides excellent utility through skill cooldown (CD) reduction, NP charge, and HP recovery. Since she can also drain an enemy's charge gauge with a skill, she has exceptional synergy in high-difficulty content.
	Pope Johanna (★5) She can fight while supporting the party with a 20% NP-per-turn engine, offensive buffs, and Arts Critical buffs. Ibuki-Douji (Berserker) can reduce Pope Johanna's skill cooldowns (CD), which makes it much easier to rotate and reuse her skills.
	Yui Shousetsu (★4) Since Ibuki Douji has both Buster and Arts buffs, she can receive both the Critical Strength and NP Damage buffs from Yui Shousetsu's Noble Phantasm (NP). Additionally, the 20% NP battery makes it easier for her to use her NP, while Yui Shousetsu's skills provide an Arts buff and an NP Damage buff to further increase her damage output.
	Xu Fu (★3) She provides an Arts buff, an NP Gain buff, and a 30% NP battery, making her a great support option for looping systems. She also excels at generating critical stars with her Noble Phantasm (NP), ensuring high consistency for Ibuki-Douji (Berserker)'s critical hits.
	Oberon (★5) He provides up to a 70% NP battery and a high-multiplier NP Damage buff. Even if the attacker receives little benefit from Buster buffs, he remains a highly viable option for the final push.

Recommended Skill Leveling by Priority

Skill 1	Priority: ★★★ In addition to ATK Up + Critical Strength up for all allies, you can boost the NP gain of allies in Summer Mode for the whole team. It boosts damage and makes NP gain easier, so level it up alongside the other skills.
Skill 2	Priority: ★★☆ You can boost the multiplier of the single-target Buster/Arts Up buff, which boosts damage, and since it also has a Cooldown -1 effect, reusing skills becomes easier. Level it up alongside the other skills.
Skill 3	Priority: ★★★ At Lv10 the single-target NP charge becomes 50%. It makes activating the NP easier, so prioritize leveling it, though the other skills are also high priority. You can also boost the multipliers of star gain each turn and star concentration up, making criticals easier.
