Boss Analysis

  • This challenge quest is a draconic melee with a Siegfried empowered by Fafnir's protection. Success will depend on dealing with Siegfried's incredible defense.
  • Siegfried will start the final wave with a fully charged hard-hitting AoE Noble Phantasm at the ready. Plan ahead and bring invulnerabilities / Evasion or stall for more time through stuns, charms and NP drain. Alternatively, let his NP kill one of your Servants to apply on death CEs like 500-Year Obsession.
  • Siegfried has a passive demerit that increases the NP gained from hitting him. This is fantastic for Servants with a high innate NP generation rate as they can continuously spam their Noble Phantasm.
  • Siegfried’s main gimmick is his 200% unremovable Defense buff and further damage reduction. There are still several ways to deal damage to him, by either using Defense Ignoring Noble Phantasms (Sakata Kintoki, Okita Souji, Emiya), stacking attack up buffs and defense down debuffs, Damage over Time (Burn, Curse, Poison damage), or flat damage passives (such as Divinity or from Craft Essences such as Volumen Hydrargyrum).
  • Siegfried can instantly increase his NP bar by one with his Golden Rule skill, and can clear debuffs with his Disengage. Both can be quite annoying, particularly Disengage for any team that relies on Damage over Time. Siegfried's Golden Rule will not lead to unpredictable NPs for as long as the Wyverns remain alive.
  • However, the two Wyverns can be dangerous if left alive as they deal critical damage often. Even though leaving them alive will reduce Siegfried’s actions per turn, the Wyverns can cast a skill that instantly kills the targeted Servant. The Wyverns will be more prone to using this skill once Siegfried falls, but Masters should be careful about leaving these Wyverns alive for too long even if Siegfried is alive. Killing them would remove a random element from the fight.

Team Composition Recommendations

  • The fastest way to deal damage against Siegfried is to use Servants with Defense Ignoring Noble Phantasms.
    • Defense Ignore only ignores up to 100% of a Defense up buff (while Siegfried has 200%) and thus it is recommended to stack multiple layers of damage buffs on top to maximize damage output.
    • Due to the way damage buffs are multiplied with one another, buffing with, say, a Buster Up is fairly ineffective if the target has a 90% defense up. However, Attack up buffs and Defense down debuffs cancel out enemy defense up buffs directly and add a lot more damage until the defense is completely broken (as they are additive buffs to defense).
    • Thus, the easiest way to gain access to enough damage to obliterate Sumanai, is to stack plenty of attack up buffs (or defense down on Sumanai) on top of a defense-ignoring Noble Phantasm wielding Servant. The resulting damage will be high enough to take out a significant chunk of Siegfried's HP.
    • Preferably, this team composition would be made up of one main damage dealer (the one with a Defense Ignoring Noble Phantasm) and two dedicated supports who can provide buffs and protection.
    • The Event Craft Essence (Princess of White Rose) should be equipped on the main damage dealer of the team.
    • With strong enough buffs and Servants, the fight can be over relatively quickly. But make sure to bring some protection/measures for Siegfried's first NP such as a stun from the Chaldea Combat Uniform or a well-timed Invulnerability/Evasion.
  • A decent way to do additional chip damage to Siegfried is through Flat Damage Passives.
    • These include Servants with Divinity / Core of the Goddess, or utilizing Craft Essences that grant a flat damage bonus.
    • Focusing only on this method of damage is incredibly slow, due to flat damage being generally weak but it can be combined with the other methods.
  • Abusing Buster Chains is another way to circumvent Siegfried's defensive threshold.
    • All cards in a Buster Brave Chain gain bonus damage equal to 20% of the Servant’s attack stat. Notably, this bonus damage is flat, meaning that it is unaffected by defense buffs/attack buffs, or class advantage. The added flat damage is a good boost to keep an eye on, but assembling 3 Buster cards can be reliant on drawing the right cards.
    • These Buster chains are excellent ways to chip away at any remaining HP, but generally relying only on Buster chaining isn't enough.
  • For some more unique and quirky strategies:
  • Damage over Time works on Siegfried but it will take a long time to accumulate enough damage to take him down.
    • Furthermore, relying on damage over time leaves one vulnerable to Siegfried’s debuff-clearing Disengage. It is recommended in this case to bring Servants who can re-apply them easily.
    • Craft Essences such as 500 Years of Obsession (2-turn NP Seal and curse damage upon equipped Servant’s death) can be put on allies in the frontline and letting them take Siegfried’s Noble Phantasm to trigger its effect.
    • Survivability is very important for this strategy as the Servants lack the damage to end the fight quickly. It is highly preferable to have a team capable of stalling for multiple turns in the party.
  • Last but not least, for players who have Angra Mainyu, his Noble Phantasm can bypass Siegfried’s protection completely.
    • This strategy is highly gimmicky, but can work if players can keep him alive for multiple NP attempts with Guts (from Servants like Irisviel).

Budget Team Recommendations

  • General Strategies:
    • As per usual, make sure to abuse the first two waves to charge NPs and have skills at the ready.

    • While there are various ways to pierce Siegfried's defense, the easiest and most straightforward way is to use (buffed) defence-piercing NPs.

    • Newer Masters with small rosters and/or low level skills should aim to borrow Kintoki as he can single-handedly carry the fight with the event CE.

    • For Masters looking for more (damage) support, focus oning bring as many attack buffs / defense downs as possible. The table below lists all possible options, but Waver is as per usual never a bad choice.

    • Make sure to bring some defense options to counter the first NP if one-shotting Siegfried isn't an option.

    • A triple Buster Servant like Heracles can still do some damage to Siegfried in a last man standing scenario.

  • Strategy 1: All Aboard the Kintoki Train
    • Sample Composition: Kintoki + Stheno + Waver

    • Sample (f2p) Composition: Kintoki + Mash + Shakespeare (David backline)

    • Kintoki is a downright incredible pick for this quest. He ticks all the anti-defense boxes. Not only is a he divine Servant, he has 3 Buster cards to do Buster-y defense-pierce goodness with. His NP pierces defense and his main steroid is an impressive 50% attack boost. Furthermore, a 50% NP gauge boost ensures his NP is ready when it needs to be. A buffed up NP-BB chain from Kintoki and Siegfried may well die immediately depending on the amount of buffs and NP levels.

    • Kintoki is fragile though and newer Masters may find that they need multiple Kintoki NPs to finish Siegfried off. Bring some protective measures (Mash, taunts, David's team-wide Evasion, etc.) to keep him alive.

    • Charge Kintoki's NP on the wave 1 and 2 Wyverns and launch it on the first turn. Between Siegfried's NP gain weakness and Kintoki's soon-to-be-off-cooldown NP gauge boost, a 2nd NP can be launched again soon.

    • Considering debuffing Siegfried on turn 1 of wave 3 with various NPs like Waver's or Saint Martha's before launching Kintoki's powerful NPBB chain on turn 2. Use the stun from the Chaldea Combat Uniform to buy time and to swap in more buffs (don't forget about the Ox-demon King CE).

    • For Masters without good Servants to swap in for buffs, both the basic Mystic Code Chaldea (more damage) and the Atlas Academy Unform (cooldown reduction for faster 2nd NP) are excellent picks to support Kintoki with. Both Mystic Codes can protect Kintoki.

    • Recommended one-shot Composition: Kintoki + Offensive Support + Offensive Support + (Order Change) Ox-demon King Offensive Support.

    • Recommended budget Composition: Kintoki + Defensive Support + offensive/mixed support.

  • Strategy 2: Other defense-ignoring Servants
    • Sample Composition: Lu Bu + Waver + Shakespeare

    • For a list of the at least decent Servants with a defense-piercing NP, see the table.

    • By borrowing a powerful support, these Servants can still take down Siegfried but will require more effort. Except for Lu Bu, none of them are capable of doing a Buster chain by themselves nor do any of them possess Divinity. Instead they can abuse the increase NP gain rate to spam their NP in quick succession.

    • Forming a team with two defense-piercing Servants (for example fielding both Nero and Okita) is perfectly viable too although a max limit-broken CE is preferred for this node.

    • Try to bring at least a couple of defensive measures as the fight will generally take a bit longer.

    • Both the Mystic Code Chaldea and the Chaldea Combat Uniform perform well.

    • Recommended Composition: Combination of one or two defense-ignoring damage dealers and supports.

  • Alternative fun Strategy: Charm-Locking Divine Snakes
    • A popular version of abusing divinity is to use a Charm-Lock team by using Euryale and Stheno. These Servants not only possess a high Divinity rank, but they can keep Siegfried at bay by not allowing him to act. Furthermore, their NP generation rate is very good.

    • Unlike the Gawain and Hercules fight though, Siegfried is accompanied by annoying minions that can frustrate the strategy. Try to remove them quickly (if need be by using a powerful AoE NP option like Arash).
