“Servant, Sieg. I'm sorry, I'm just a homunculus.”

Originally a nameless homunculus, Sieg gained his name after receiving a certain dragon-slaying hero’s heart and powers during the Great Holy Grail War of Fate/Apocrypha. A Caster-class free event Servant, he is known for his high AoE Arts NP Damage and NP gain, the latter of which is a manifestation of his homunculus origins.

As a welfare Servant, Sieg has easy access to a level 5 on his NP Ákafiloga All-gríð, which allows his NP damage to keep up even against those of his higher-rarity counterparts. While his main damage boost Magecraft is weaker compared to other similar skills, it is made up by Ákafiloga All-gríð’s defense down, which is applied before the NP’s damage is dealt. Sieg can further boost its damage against dragons through his third skill Dead-Count Shapeshifter. Furthermore, each of Sieg’s three skills provides some sort of important boost to his overall NP gain, cementing his place among the game’s AoE NP loopers.

Sieg has two primary weaknesses. The first is his lack of any notable defensive skill, with Artificial Hero (Fake)’s Max HP Up being the only thing he has close to a survival tool. Secondly, despite his impressive NP damage, a mix of low ATK stat as well as one-turn damage boost skills mean that Sieg’s damage out of his NP turns can feel rather underwhelming.

Nevertheless, with great offensive capabilities and relatively minor setbacks to his name, Sieg is definitely a very powerful AoE Caster option who is a match even for his higher rarity counterparts. Despite the often heated arguments surrounding his character, Masters willing to invest in him are sure to find great value in the homunculus-turned-hero’s abilities.


High AoE NP Damage 

With an easy NP5, along with access to Arts Performance Up and defense down, Sieg’s NP damage ranks highly among all AoE Casters. As an added boon, the aforementioned defense down is built-in to his NP and is applied before damage is dealt. This means that unlike skill-based damage boosts, it is not locked behind any cooldown, and thanks to the debuff’s 3-turn duration, Sieg can potentially stack oftentimes two, rarely three of them. As the cherry on top, Sieg is able to effectively double his damage output against enemies with the Dragon trait (more on this will be explained below).

NP Spam Potential

Sieg’s base NP gain, particularly on his NP, favors comparably to other Arts AoE Casters, and he tops it off with various methods to make NP looping easier. Of his three skills, first skill Artificial Hero (Fake)’s 3-turn NP Gain buff is the largest contributor in terms of refund consistency, but the flexibility of Dead-Count Shapeshifter’s instant NP Charge is not to be underestimated either, particularly as it helps him fire NPs right off the bat.


At first glance, Sieg’s anti-Dragon boost may seem situational at best, even considering the few Assassin and Berserker Servants who possess the trait. However, while it is indeed more of an added bonus, the damage increase it provides rivals that of class advantage at max level, which means that Sieg can be used to farm most class stages as long as the boss has a Dragon trait (and Sieg at least deals neutral damage to them). Notably, all incarnations of Altria Pendragon and Mordred have this trait, which greatly widens the amount of possible targets.


No Hard Defensive Skill

Despite a decent HP pool and a Max HP Up in his first skill, Sieg is otherwise a relatively squishy Servant, as he has no way to reduce or defend against incoming damage. While this is generally not an issue for farming stages (which is where he will mostly be used on) it makes him dependent on his allies for survival when used in more damage-heavy stages.

Low Normal Card Damage

As with most other Casters, Sieg comes with a below average ATK stat and a 0.9 damage modifier. While these weaknesses are not as felt in his damage output (due to its NP5 status) they otherwise reduce his damage output quite significantly. Fortunately, his NP’s 3-turn defense down patches this weakness somewhat, but generally, it is recommended to not rely on his normal cards for damage.

All three of Sieg’s skills are meaningful to his primary NP spam role in some way, and they should be raised to respectable levels if he is to be used, with additional levels providing extra reliability. Maxing all three is recommended for three-turn farming purposes.

  • Artificial Hero (Fake) B+ is arguably most important to Sieg’s NP spamming capability thanks to the NP Gain Up’s 3-turn duration, as well as its multiplicative nature with Arts Performance Up buffs. The skill’s Max HP Up in comparison is more of an added bonus, though the boost to survivability may let him live through some very clutch moments. It is recommended to level this skill first to increase Sieg’s NP refund.
  • Granting a boost to Sieg’s Arts Performance for one turn, Magecraft C increases not only the damage, but also the NP Gain of his Arts cards. As a farming Servant, it is often the case that NP spamming reliability is more valuable than extra damage (especially where offensive supports are involved), which leaves this skill’s leveling priority under that of Artificial Hero (Fake). Still, it is recommended to level this skill second, as the extra damage can be used to more easily trigger overkill and helps ensure consistent kills on enemies.
  • Dead-Count Shapeshifter EX is mainly prized for its NP Charge effect, which can be utilized at any time to top off Sieg’s NP gauge. Notably, it allows instant NP with Kaleidoscope even at skill level 1. The amount of NP gauge granted scales with level up to 30%, making this a worthwhile investment. As an added bonus, the anti-Dragon buff also scales with level. In general, this skill is high priority.

Craft Essence Recommendation

As with most farming Servants, Starting NP Gauge CEs are Sieg’s first choice, but he also benefits greatly from Arts Performance Up effects due to their NP refund benefits. Attack Up and NP Damage Up can also be utilized, though it should be noted that the latter stacks additively with his anti-Dragon buff.

  • Kaleidoscope / The Imaginary Element (LB): Thanks to Sieg’s third skill, he is capable of unleashing an instant NP with CEs of this category, which is a great boon to his farming capabilities. They are his go-to CEs, and should ideally be used in most farming runs. Note that The Imaginary Element is ideally max limit broken.
  • Painting Summer / Distant Pilgrimage / Dive to Blue / Golden Sumo: Boulder Tournament / Holy Night Supper: In stages where turn count is not a concern, these CEs can be used in place of the above category. Though they come with less amount of initial NP charge, they make up for it through various offensive buffs, which aids Sieg in killing enemies more reliably.
  • The Black Grail: It is important to note that the NP Damage Up buff stacks additively with Sieg’s anti-Dragon buff, which greatly reduces this CE’s effectiveness against certain targets. Otherwise, however, it provides by far the greatest damage increase to his NP damage, and should be used against higher HP bosses.
  • Formal Craft / Projection: As Sieg’s own Arts Performance Up lasts for only one turn, these CEs are decent generic choices, boosting both the damage and NP gain of his Arts cards. 
  • Sign of Smiling Face / Cute Orangette / Kaleid Sapphire / Emerald Float : These CEs are hybrid versions of the above categories, and can be used as an alternative to pure Arts Performance CEs.

Character Info

Some try to grasp the unreachable stars through sheer determination. He, on the other hand, was one who managed to shoot down the stars.
He's just an ordinary homunculus, just an ordinary human being.

Profile 1

Height/Weight: 165cm, 53kg
Origin: Fate/Apocrypha
Region: Romania
Alignment: Neutral-Good
Gender: Male
He is a Servant as well as a Master.

Profile 2

A Holy Grail War that took place in Romania...
He is one of the homunculi mass-produced for the purpose of supplying magical energy during that Great Holy Grail War. Under ordinary circumstances, he would simply have died and been discarded once his magical energy was drained. But the determination of this homunculus to survive lead him to obtain Siegfried's power, making him a central figure in the Great Holy Grail War.

Profile 3

Independent Action: EX
A subspecies of Servant possession. Other than requiring magical energy whenever he goes into combat, he is no different than any other human being in all aspects. Normally, he would also be of a typical human age, but...

Homunculus: C+
A homunculus manufactured using the Einzbern Family's methods and technology. This may be a coincidence, but he was born with a personality AND a superior talent for magecraft.

Artificial Hero (Fake): B+
A Pseudo-Hero created after inheriting the hero Siegfried's heart and having electricity from Frankenstein's Noble Phantasm surge through his body. It may be temporary, but by combining this skill with the Dead-Count Shapeshifter Command Spell, he can become a hero...a Servant.

Magecraft: C
Natural talent a homunculus possesses, since they have been manufactured using magical circuits.
He is able to destroy anything, no matter what substance it is made from or how sturdy it may be, by analyzing the target's components and composing their antithesis to disrupt the overall structure.
However, there is no other use for this skill.

Dead-Count Shapeshifter: EX
Dragon Communicating Command Spell.
With his Command Spell, he is able to use Siegfried's heart, which was implanted into him, as a catalyst to temporarily transform into Siegfried.
The transformation lasts about three minutes.

Profile 4

[Ákafiloga All-gríð]
Rank: EX
NP Type: Anti-Personnel (Self)
Range: 0
Maximum Targets: 1
(His breath range is about 50)

Scorching Dragon's Breath, Incinerator of All.
A Noble Phantasm that allows temporary transformation into the dragon Fafnir. He then uses a powerful dragon breath attack to inflict catastrophic damage. This Noble Phantasm originates from his turning into a dragon and flying away in his past life.
According to him, there's not much difference between being human and being a dragon.

Profile 5

He has no history of significance.
It may be a bit of a stretch to call him pure, since he was merely resigned to the fact that his purpose was to die. His appearance, intellect, and mindset are similar to a teenager's, but he is in fact considered to be a perfect being, quite different from a normal human.

But as he lived on, that perfection began to fall away.

A certain priest detested that aspect of him, but the boy himself embraced his flaws and ultimately abandoned his perfection.
In the end, it was that very conflict that would end the Great Holy Grail War.

Profile 6

Clear Apocrypha/Inheritance of Glory + Bond Level 5

As Sieg transformed into the evil dragon Fafnir, he carried the Greater Grail to the Reverse Side of the World to prevent the Third Magic from affecting the world. There he waits, hoping that she will come to see him one day.

Sieg as a Servant is more like a terminal rather than an imitation.
Just like Jeanne Alter the Avenger, the day that humanity resumes properly will be the day he disappears, as he will have fulfilled his role.

Victory 2 Master, are you all right? Okay. Good.
Level up I've become more effective as a Servant...
That's a surprise.
Ascension 1 Unfortunately, this form of mine won't change.
I don't think there's any point in Ascending me.
Ascension 2 I don't think there's a point in this... Then again, this is something you did for me...
Thank you.
Ascension 3 Even though my appearance doesn't change, my will to fight is increasing.
That isn't so bad.
Ascension 4 I never imagined you would go so far for me... I don't know what to do other than to show my appreciation.
Anyway, Master...thank you. You've made this homunculus the happiest person on Earth.
Bond Level 1 Master? What's going on?
Bond Level 2 Did something happen? I'm like a statue, so if you have any secrets, don't hesitate to say them aloud. There's no risk of me telling anyone.
Bond Level 3 Hey, Master.
If you have any problems, tell me. I don't know if I can be of help, but... Someone once told me that it can make you feel better just telling someone what's on your mind.
Bond Level 4 Master. Um...
No, never mind. Forget it. Don't worry about it.
Bond Level 5 Master. Um...
I would like it if you could be my friend. I'm not sure if asking you like this is appropriate, but... No, never mind. Forget it. I'm embarrassed.
Conversation 1 I think you should go do some quests soon.
I'm hearing that some of the more hot-blooded Servants are getting pretty restless.
Conversation 2 I know I'm the Servant here...
But my brazen tone of voice is ingrained in my Spirit Origin. Sorry...please understand...
Conversation 3 Is there something I need to do?
No? I don't need to do anything? Yet you still want me to be by your side? Hm, serving others is a hard thing to do.
Conversation 4 (Jeanne d'Arc) Hm?
Oh, so the Maiden of Orleans is here too. I guess that makes sense. She would never stay idle if humanity was at risk. But I don't think she knows me, so leave her alone. She's just a vague, distant memory, even for me. And I don't see that changing unless we meet under different circumstances.
Conversation 5 (Astolfo) I knew you were here, Rider...
I don't get it, but he said my Spirit Origin hasn't changed while giving a forced laugh. Okay, let's both do our best.
Conversation 6 (Avicebron) Avicebron...the choices you once made should probably be never forgiven.
But your cry for peace...seems sincere. So, I'm happy to fight at your side.
Conversation 7 (Amakusa Shirou) He was once someone I fought against. But now that he is our ally, I shouldn't be carrying any grudges against him.
Still, I am...conflicted... And I'm sure Amakusa Shirou feels the same.
Conversation 8 (Siegfried) I never had the opportunity to have a full conversation with you. But the fact that I am here at all is thanks to you.
Thank you, Siegfried. There is nothing else I can say.
Conversation 9 (Chiron) Chiron.
Things here seem much more peaceful. If it's possible, I would like to learn a great deal from you. ...Wait a minute. It seems like a stack of homework just appeared out of nowhere.
Conversation 10 (Mordred) Mordred.
I'm glad to see you well. Did you find what you were looking for? ...I see. Let me just go and greet your father... Why are you so mad?
Likes What I like? Let's see...
Existing here...that in itself is a miracle. For me to ask for something beyond that would be too selfish.
Dislikes There's not really anything I dislike.
One should always accept what comes their way, no matter what it is.
About the Holy Grail The Holy Grail...
Sorry, but no matter how small the Holy Grail is, I feel I must take it to the reverse side of the world, so I suggest you keep it away from me. Also you shouldn't give it to Amakusa Shirou. Probably.
During an Event There's an event going on.
Good luck to you.
Birthday A birthday should be celebrated.
Summon name is Sieg.
Sorry to disappoint you, but I'm just an ordinary homunculus. I may not be particularly powerful, but the Noble Phantasm that's been registered to me might be useful in battle. Use me as you see fit.
Summon (Temporary) Let's start off with a temporary contract. This isn't my first time as a Servant, but this is the first time I've fought in my own form. You may think I'm just talking nonsense, but I'm counting on you.
Apocrypha/Inheritance of Glory 1 Okay, take all you like.
I'm sure even the Greater Grail will approve.
Apocrypha/Inheritance of Glory 2 Once you gain momentum, it's hard to stop. That's what getting points is all about.
Just be careful not to get a runner's high from it.
Apocrypha/Inheritance of Glory 3 Be careful not to eat too many apples. I can see you're very busy, though.
Plan accordingly, and do your best.
Apocrypha/Inheritance of Glory 4 I thought up all the rewards.
I'm not sure if these items are things you need right now, but I'm sure they will be of use to you someday.
Apocrypha/Inheritance of Glory 5 Have you been checking the news?
All events must end. Until then, be careful not to forget anything.
Apocrypha/Inheritance of Glory 6 Good work. Did you get all the items you wanted?
Even if you couldn't reach your goal, count yourself lucky if you got something out of all this.
Apocrypha/Inheritance of Glory 7 Would it be appropriate to play Auld Lang Syne? When I run a search in the Greater Grail, it tells me that the song should actually be called the Farewell Waltz.
