Combat Skills
Artistic Urge
Normal AttackAn attack with up to 5 sequences that deals Cryo DMG. As the controlled operator, also deals 18 Stagger.
DIVE ATTACK:
Basic attack performed in mid-air becomes a dive attack that deals Cryo DMG to nearby enemies.
FINISHER:
Basic attack performed near a Staggered enemy becomes a finisher that deals massive Cryo DMG and recovers some SP.
Brushwork Realm
Battle SkillInitial Stroke: Costs 15 SP. Si pulls an Inksoul from a target with Artful Intent. All DMG dealt and effects applied to the Inksoul will also be dealt to its host (the said target). The Inksoul lasts as long as the remaining duration of Artful Intent. After casting the skill, Si's battle skill is temporarily changed to Final Stroke.
Final Stroke: Costs no SP. Makes the Inksoul disappear early. When disappearing, the Inksoul will move to its host and trigger a burst like the ending burst of Artful Intent.
When dealing DMG or applying effects to both the Inksoul and the host, only 1 instance of the DMG or effect is dealt/applied. If the host is defeated during the Inksoul's duration, it will link to another enemy in combat and apply Artful Intent to it. This does not reset the duration of Artful Intent. If a target with Artful Intent is defeated without having its Inksoul drawn out of it, the defeated target will drop an Inksoul at its location.
Fully Envisioned
Combo SkillSi summons an Ink Lung that deals Cryo DMG. This DMG is based on the highest stacks of Arts Infliction or from a single target.

Introduction
“Hmph. Only think of me when trouble shows up?”
Si is one of the few Feranmut Proxies on Talos-II. The Feranmuts are paracausal beings native to Terra, and the consciousness that They manifest in slumber before human presence is known as Feranmut Proxy. Si's relationship with her Feranmut is somewhat complicated, but people still habitually refer to her as a Feranmut Proxy. In truth, Si is no one's Proxy. She is simply herself. Beneath her formidable and mysterious exterior lies a young soul who still holds onto hope and curiosity about the world.
In her daily life, she uses her abilities to provide comprehensive support for HAS and Endfield. In her spare time, she enjoys exploring the cities of Talos-II in search of the latest technologies and fashion trends. She follows her heart's desires and is unfettered by conventions.

Operation Prep 2
I'll help you out again. Remember to pay up once we get back to the inn.
Adding to Team 1
And don't talk to me from now on. I need to focus.
Adding to Team 2
Come on, say something. I get distracted when it's too quiet.
Switching Weapon
You chose this? Hmm... How about two strokes of ink? Mine now, you're not taking it back.
Switching Gear
It even takes my wings into account… Ahem. N... Not bad, but I won't be nice just because of this.
Talent Node Activation
Ah! Inspiration strikes! Quick, don't just stand there! Give me some paper!
Watching Combat Records
Watch it a few more times to remember... Why are you smiling? I was talking to you!
Operator Promotion 1
Just so we're clear, I'm just an honorary Endfielder, so don't expect me to do everything. Also, Endfield better be as interesting as you claim.
Operator Promotion 2
Give me your hand and let me stamp it with my tail. There... That will do. And you better not rub it off until I decide to stamp you a new one.
Operator Promotion 3
Ink Spirit, write down what the Endmin said. Every, single, word. HAS wants me to give a speech to the young Yinglungs. This'll come in handy.
Operator Promotion 4
You keep promoting me, but if you ever fail to do what you promised, I'm heading back to the inn. Keep your matters separate from Endfield. What happens between us is between us.
Operator Reporting for Duty
Hold it, keep it still! The ink isn't even dry yet... This painting's for you. What I drew isn't important. It's my seal that matters! And don't you ever forget my name again!
Standing by 1
This, then that... Alright, roll it up. Ahem. Your draft is done. Gotta be patient!
Standing by 2
You've been hanging around me for years, why can't you learn anything from me? Such as faking my signature.
Assigning to Facility
You lured me to this place just so you could sit back and relax? Not happening. You're staying here with me.
Greeting 1
Trying to walk past me? Are you pretending I'm invisible?
Greeting 2
So, that promise ten years ago. You gonna make up for it?
Dijiang Idle Chatter 1
Me? Idling around? See that porthole window? I drew an entire painting titled "Travelers Across Talos-II" on it... But someone took their time coming over, so I erased everything.
Dijiang Idle Chatter 2
Why do you keep showing up whenever I visit Dijiang? What, you saw Ink Spirits at the corner...? Ah, well... Seems like you showed up on my path on purpose!
Dijiang Idle Chatter 3
I'll paint your portrait and hang it at my place. That'll keep the waregeists away if you visit my scroll on your own... Hmm? I do have one from ten years ago. But you weren't wearing anything on your face back then.
Dijiang Idle Chatter 4
Maps, pillows, munchies, stove, stimulating tisane... Oh. Just making a list of stuff to bring to Sami. Traveling gives me my inspirations. See if you got any more ideas... Of course you're coming along, or I wouldn't be telling you all this! No, I got Ink Spirits to carry my bags around, not you, Dolt!
Dijiang Idle Chatter 5
I ran into Perlica. Miss little supervisor is just like you... Poor girl's trying to stay awake, even though she could literally fall asleep on her feet... You're exactly the same! Stop pulling all-nighters and go to sleep. Working yourself into the ground and then sleeping for ten years. Seriously?
Dijiang Idle Chatter 6
Whoa...You can see almost half of Talos-II from here... I wonder where those two have wandered off to... Wha?! Who said I miss my siblings? Don't look at me like that...! *Sigh* Fine. Maybe I miss them a little bit. Just a bit...
Offering Gifts
Here. A little gift for you, just something I doodled. Don't get too exci — Ah, wrong one! That self-portrait is just practice. GIVE IT BACK!
Accepting Gifts
Er... W-When did you start getting all formal and official — HEY! Don't you dare take it back!
Trust Dialog 1
If you've got time, swing by the inn for the welcome feast you missed. The kitchen dug up every rare ingredient we could get our hands on. Wait... Who did you say you were thanking?! Well then, it seems all the credit goes to the staff. Then I guess their heartless boss has no choice but to stop them from wasting all those precious ingredients! HMPH!
Trust Dialog 2
Take a whiff. See that cliff over there? That's where the tea bushes grow. As good as the tea is, I do have to send my best Ink Spirits to pick the leaves. A decade of work, all packed into this little jar. So you're really lucky today... Hey. Why are your teeth covered in ink? Wait... Mine too...? J-Just finish the tea. Every last drop. And stop looking at me!
Trust Dialog 3
Stop! That'll be all for today! Well, you've gotten pretty good at Weiqi. But my brother's still the best player on Talos-II. You're nowhere near his leag... What? This is the third time I've brought up my siblings this month? I-I'm not saying I wish they were still around! Just look at the mountain, the inn, and the fact that I at least got... AHEM! This place is lively enough as it is.
Trust Dialog 4
Already making a distant trip before full recovery? What are you made of, Xiranite? Really think you can't fall apart? Hmph. I was hoping that stupid habit of self-abuse disappear with your memories, Dork-Min! Gimme the mission details and I'll go in your place! Remember, you owe me one. AGAIN!
Trust Dialog 5
Sit. Miss the sunrise? Just paint it with the brush. Back then, you made uninvited visits when I was alone. You had a way of turning ridiculous ideas into comforting words... Fine. I know my words won't bring back any of your lost memories right now. But if you dare to forget anything ever again, I won't talk to you for the next ten... no, one hundred and fifty years!
Chat 1
I've been getting more and more people wanting to visit the scroll, but the inn wasn't built to handle so many visitors. The staff suggested putting up a bulletin board in the main hall... It sounds like a great idea, but that means I'll be getting a lot of random suggestions. I-I just don't have time to go through everything. So, could you sort through them first... then I can just focus on the useful ones?
Chat 2
The pinnacle of forging is to compress every manufacturing step within a single breath and turn every idea into reality. Just like this shield I'm holding... What? A defective pore...? AHEM. Oh yes, this is just a sample piece. Tiny flaws are expected, and definitely unrelated to the mastery of my powers.
Chat 3
Heard about chubby skydrummer plushies? I love chubbies and got a load of them in my inn. But chubby skydrummer plushies are exclusive prizes for the Wuling "Sketch and Guess" game, and it can't be played alone... Listen up, the next season is coming. I'm gonna teach you the tricks and you better learn... Of course you're drawing and I'm guessing! Do I look like the sort who cheats in games?
Chat 4
Job Rusher is always slacking off, Speed Dasher is so big he could hardly move, and Loud Speaker greets guests so softly you'd miss it if you blink. It's been decades, and I gave up trying to fix up their habits. Oh? Well, they had nowhere else to go so I added them to the scroll. I can send them away... but I prefer my inn messy than quiet.
Chat 5
I used to hang around my siblings and play Weiqi, listen to their discussions, and then practice reading, calligraphy, and painting at night. During our free time, the three of us traveled around Talos-II ... but soon they sent me off to Hongshan. They probably saw Talos-II as a breath of fresh air and thought I'd never truly like it if they were always around. I get where they were coming from. But you can't just leave your little sister somewhere and barely visit her...
Topic: Yinglung Special Task Force
Yeah, I was there when HAS formed the Yinglung Special Task Force. But all I did was teach them a few tricks. Why wouldn't I spend more time with them? 'Cuz the Yinglungs are full of stubborn types like Li Zhiyan. Hang around them long enough and they'd freeze the air itself solid. But she seems to have figured things out a bit more after spending time with you. Hmm... Eh, Endmin, why not take my place and go teach them for me?
Topic: Feranmut Power
The Endfield HR database has issues. For the "Skills" section, I listed twelve items, including martial arts, literature, painting, metallurgy, law, gardening... and then it just threw an error. What do you mean I have too many skills? Look, occasionally failing at something doesn't take them away. You'd better make yourself clear, or I'm not letting this go!
Topic: Wings
My wings are pretty, right? When I was young, I dreamed of them sprouting and spreading, so I drew them on my back after I woke up. My sister wouldn't stop nagging about it... It's just decor. But she said I use them in fights to look intimidating. Hmph. That's a baseless accusation. I mean, who even does that? So childish!
Topic: Ye Minghe
That kid with bright hair? We've known each other for quite a while, and he's always so annoying. Sometimes he only cares about that jet-black gallopbeast of his, and he never stops going, "The Imperial Guards must uphold their duty..." And that's why he's so difficult, because he means every word he says. Kind of like you, to be honest. Wait, you are the one who influenced him! Anyway, if he barges into my scroll again, you're gonna pay.
Topic: Family
I don't know where my siblings have gone. After everything they've been through, they finally have time on their hands. Maybe they're wandering all across Talos-II. Maybe they'd... HEY! Job Rusher! Didn't I tell you to clean properly? Especially the paintings, calligraphy, and the Weiqi boards. What if they come home and see this mess? You're gonna get me in trouble!
Topic: Sui
Sui is the worst Feranmut. Ever. Even in sleep, He won't stay still, always scheming to make things hard for Yan with his twelve proxies. And in the end? Every proxy got their own ideas and made things difficult for Him. As for my relations with Him ... I wouldn't be around if they didn't bring the last bits of his soul to Talos-II. But we're different. There is nothing between us, one way or the other. The debt's settled and it's as clear as day.
Resource/Collectible Detected 1
Don't miss this spot.
Resource/Collectible Detected 2
Look, hidden spoils.
Unexplored Area Detected
Interesting place. You'd miss it if you weren't paying attention.
Powerful Enemy Discovered
Careful. That one will take a few extra strokes.
Mining 1
Forge of the Sky, Metals of the Earth. Talos-II does have plenty of rare stuff.
Mining 2
Leave it to me. It'll be done in an instant.
Opening a Crate
Don't wait for an inspiration. Look for it.
Acquiring Aurylene
Hmm. If I mix Aurylene with ink, what could I paint with it?
Eliminating the Blight
Come to think of it, maybe my Ink Spirits could also take care of this.
Rest
Always rest when you can, because nobody can paint Talos-II in a single stroke.
Tactical Use 1
I know a bit of herbs and mending too.
Tactical Use 2
That made things feel a lot better!
Danger Warning
Watch over there!
Injured
Did they soil my wings?
0 HP
No longer ... interested...
Team Encouragement 1
Ah. A promising generation.
Team Encouragement 2

Encouragement Response 1
You're not being "polite", right?

Alright, alright, don't get distracted.
Combat Begins 1
End this before the day grows dark.
Combat Begins 2
Show me what you can do, younglings.
Combat Victory 1
This is way more fun than staying in the scroll.
Combat Victory 2
I'm so inspired. This field trip is worth its while.
Combat Victory 3
Over already? I assume you still got the strength to grind ink for me.
Combat Victory 4
It was hard, but we won. Don't go slumping around like that.

Winning is great, but it's okay to lose. I'm around, so there's nothing to fear.
