Botzu's Quick Evaluation

+ E2 Talent: Gains 7-16 SP on deploy
+ S3: Will blow up anything short of the very strongest enemies with 1 use
+ S2: great consistent damage option
+ AoE Caster damage at a lower ST Caster Deployment Cost
- S3: short Duration and long cooldown can leave the team flat if she is the main source of damage

Operator Overview

"Why does there have to be conflict in this world?"

The volcanology and natural disaster expert Eyjafjalla is a powerful single target Caster who can deal AoE damage. Her Oripathy infection, presumably due to research near volcanic areas and exposure to particles with Originium, impairs her hearing and other senses.

Eyjafjalla’s fantastic kit can obliterate bosses and multiple targets alike. Her first skill, Duetto, is an Attack Speed Increase, which is also an ATK Increase after the first cast. Ignition, her second skill, lets her do great Area of Effect damage and decrease enemies’ Resistance.  It does excellent consistent DPS to both single targets and groups, making it her most commonly used Skill.  Her final Skill, Volcano, increases damage, range, attack speed, and number of targets by a considerable amount. It does extremely high damage, and can melt down groups and bosses alike.  It's short duration and long cooldown, however, can leave you flat in between uses.  To top off her amazing Skills, her Talent, Pyrobreath, buffs the ATK of all Casters on the field when she is deployed.

Eyjafjalla has the Deployment Cost of a single target Caster with AoE Damage potential that rivals the best AoE Casters. This makes Eyj a strong Caster choice in almost all situations.  Float this cute little Caster onto the battlefield and enjoy watching things melt!

Newbie Tier List Explanation

Does absolutely everything. Has ST-Caster deploy cost and yet does AoE damage better than the actual AoE Casters.

Elite Promotion Discussion

  • 3rd Skill - Volcano - Literally erupts and melts everything close to her.  It has a huge range, hits multiple enemies, boosts her Attack, drastically increases her attack speed, and doubles her adorableness.  It makes her even better at performing the Caster role of melting high Defense units, is a great Boss and Elite Killer, and can sometimes satisfy AoE needs.  The relatively short duration and long cooldown means it has to be managed properly, but it is widely considered to be a very powerful and widely applicable E2 Skill.

  • Talent 2 - Wild Fire - She immediately gains a random number of Skill Points on deployment. More ways to collect salt!  Useful in situations where having her first Skill use faster is nice, but not particularly game-breaking.

  • Talent 1 Upgrade - Pyrobreath - A good increase to an ATK buff for all Casters on the field.

S2M1 Breakpoint

S2M3 S- A S+

Even after three years of content, Eyjafjalla still reigns supreme as the top caster in the game. Although there are many reasons for this, a big one is that she also has two of the best Caster skills which gives her a lot of flexibility in how she deals out damage, and you'll definitely want to Master both of them. After the S2M1 breakpoint, focus on her S3M3 which is one of the best burst DPS skills in the game for both Story and Advanced clears. Her S3 needs Mastery to really reach its potential since it has some pretty incredible gains including an extra target at M3. Don't cheap out on the remaining S2 Masteries though, especially for more Story and Roguelike-centric players who need consistent arts DPS.

Integrated Strategies Tier List Explanation

General IS Notes

+ Most popular Caster for the gamemode.
+ S2: Very powerful consistent splash Arts DPS that can deal with most armored threats and maps with large enemy hordes.
+ S3: Very strong multi-target burst of Arts damage with a massive range that can be used as a helidrop.
- Talent contains a modicum of RNG, which isn't ideal for this gamemode.

IS2 Specific Notes

Essentially as good here as she is elsewhere.

Good Relics

Broken Wand - Malediction
'Brilliant Lament'

Relic Interactions

Doesn't interact particularly well with any specific relic set, but DPS Casters have very good generic options.

Recommended Promotion

E2 heavily recommended for access to S3 and Masteries.

Base Skill Analysis

Eyjafjalla gains here second RIIC Skill at Elite 2.

As if you needed more reasons to Promote her to E2.  This is one of the strongest buffs available for the HR Office.

Profile

Eyjafjalla, volcanologist, Catastrophe Messenger. She is exceptionally talented in the use of advanced Originium techniques and high-energy Arts.
Currently undergoing treatment at Rhodes Island, Eyjafjalla provides support in Catastrophe research, environmental observation/assessment, assistance in traversing dangerous terrain, among others.

Clinical Analysis

Increase Trust to 25.
Imaging tests for this Operator showed blurry outlines of internal organs with visible dark spots. Unusually high concentrations of Originium particles were present in her circulatory system, indicating infection and confirming her as Infected at this stage.

[Cell-Originium Assimilation] 8%
Eyjafjalla showed conspicuous symptoms of infection, with corresponding deafness.

[Blood Originium-Crystal Density] 0.5u/L
The level of Eyjafjalla's internal crystals are comparatively high.

Archive File 1

Increase Trust to 50.
When Eyjafjalla showed up at Rhodes Island for the first time, the personnel leading her to Human Resources noticed some odd behaviors right off the bat: She couldn't make out what people were saying and would sometimes run right into things. People assumed she was some Operator's visiting little sister, or an intern sent by the pharmaceutical department.
A few days later, they were shocked to receive a notice from the executives, approving the Infected Eyjafjalla for missions and the research of Arts and Catastrophes as an official Rhodes Island Operator.
It turns out the little girl they overlooked was a legend among the most renowned academies in Leithanien, fueling speculation about her level of education.
The optimists believed having a young person in the Arts Department would bring some much-needed energy to their somber daily grind. They debated in low but excited voices over who would mentor her internship.
The pessimists lamented that as an Infected, no one could predict where Eyjafjalla might end up in the future.

Archive File 2

Increase Trust to 100.
According to forms filled out by Eyjafjalla, she was born to a prominent academic family in Leithanien. Her parents worked at William University, her father a graduate professor for the School of Originium, her mother an environmental and ecological research specialist. The couple died in a volcanic eruption during a survey.
Eyjafjalla's parents had begun a project to study natural Catastrophes on Terra, and the volcano was a key site. Among the files Eyjafjalla took with her to Rhodes Island, she treasured the report on that volcano most of all. She didn't want the study to end with the passing of her parents, so she decided to continue it in their stead.
Volcanic research must be done on-site before eruption and required long-term close-range observation. Particles with Originium components tended to be common in volcanic areas, and cooling lava constantly turned over new Originium veins, making the region a breeding ground for Oripathy. This is believed to be the reason for Eyjafjalla's infection.

Archive File 3

Increase Trust to 150.
Eyjafjalla's physical symptoms are very obvious. Oripathy has impaired her hearing considerably, sometimes robbing her of the sense entirely. Fortunately, the impairment has slowed given treatment at Rhodes Island.
Eyjafjalla typically uses a hearing aid, or asks her conversant to repeat loudly themselves in order to communicate.
In addition, certain facial expressions and body language have also proven effective. For example:
Shaking one's head: Unsuccessful dialogue.
Shaking one's head with a surprised expression: Very likely some words have been misunderstood and should be clarified immediately.
Nodding: Successful dialogue.
Noding with a positive expression: Idea successfully communicated, proceed with dialogue. Still, one must be mindful of the context, since the present dialogue might be built on the pretext of a previously unnoticed misunderstanding.
Repeating a word or sentence multiple times: Eyjafjalla is confirming what's been communicated to her, respond positively and mind one's volume.
Glassy-eyed or negative expression: Misunderstanding has possibly occurred. Review previous dialogue to avoid greater misunderstanding.

[CLASSFIED]
I've perused Eyjafjalla's files and a draft of her thesis.
'The Impact of Underground Originium Veins on Volcanic Cycles' and 'Investigative Report on the Correlation Between Originium and Natural Catastrophes,'plus a few other analyses are... very well done and reasoned.
Also, very dangerous.
I hope everyone realizes she is asking dangerous questions in dangerous areas--and not just academic ones.
You do know ants, right? Then you should know ants love carrion.
Even though the carrion is still rotting, the ants will still rip it to tiny chunks and carry them back to their nest to feed the whole community.
Ants must grow stronger to survive in the world.
Do you get it? If the carrion is Originium, we are feeding our community with it for everyone to grow stronger. And the purpose of that is to defend ourselves... and maybe oppose potential changes in the future.
Yes, according Eyjafjalla's thesis, Originium is a natural Catastrophe.
But we cannot stop, and will not stop.
...
Let the child continue her research, for now.
Before she can be certain of her own future.
—Excerpt from a closed-door conference, spoken by■■

Eyjafjalla's pets
serve a similar role as Operator Mousse's 'kitties.' Eyjafjalla's dark-woolen companions appear identical to normal animals in physiology and behavior.
Eyjafjalla calls them 'little black sheep', claiming they were gift from her mother when she was still alive.
Unlike the naughty 'kitties', the little black sheep are submissive and sluggish, their idea of fun is to nap in Eyjafjalla's room or some place spacious at Rhodes Island.
They helped Eyjafjalla with many things, like move books and deliver goods. They even make good fluffy pillows for her to lay her head on.
[Classified Log]
This is not really confidential information, but something I believe is noteworthy.
Although Eyjafjalla dubbed them 'little', they're still big pets.
Given their size, it is odd that they're hardly spotted at Rhodes Island.
On retrospect, it is suspicious that they only showed up to graze or when Eyjafjalla needed them.
Another usual phenomenon is when they give off high heat when angry or excited, possibly burning your hand when touched.
The truth behind all this is worth investigating.

Appointed as Assistant Professor, I've finished all my Catastrophe studies notes. Do you have any more I could read?
Talk 1 Huh? What? Why do I call you 'Professor'? Well, you're an expert on Catastrophe studies, so you're like a professor, right? Aren't we all supposed to address our superiors with respect?
Talk 2 What? Say that again? Oh, you're wondering why I'm hard of hearing? Well, it was because I got infected with Oripathy back when I was doing research near a volcano...
Talk 3 Besides completing the tasks you give me, I have to go to Dr. Kal'tsit regularly for checkups. The doctor said my symptoms are pretty serious...
Talk after Promotion 1 I have to work hard to finish the research my parents began! I want to prove that their work was meaningful, and that it could maybe even change the world!
Talk after Promotion 2 My parents... they've passed on. A pyroclastic flow hit them when they were conducting studies near a volcano... I have to pick up where they left off and finish their research, no matter what!
Talk after Trust Increase 1 My playmates? I'm pretty friendly with Mousse and some others, so I don't feel lonely at all! If possible, I'd love to start a book club with them too. Could we hold our club meetings in your office, Professor?
Talk after Trust Increase 2 Dr. Kal'tsit told me... I'm losing not only my sense of hearing, but my sense of sight too. Oripathy really is relentless, huh?
Talk after Trust Increase 3 How could I tell you were behind me? Because I could feel your warmth! My eyesight and hearing aren't as sharp as they once were, but my other senses are still the same. Can't bring me down this easily, you know!
Idle Professor! Oh... You're asleep...?
Onboard I'm Eyjafjalla. My career before joining Rhodes Island was in the field of volcanology. I'm a bit hard of hearing due to my Oripathy. I just hope I won't be a burden to you, Professor.

Description:
The more you learn about Eyjafjalla, the more you realize a titanic power to rival volcanoes lies stored in her small stature.
If she could, she'd want to devote all of her Originium Arts to academic research, but reality often leaves us without a choice.
On the battlefield, her Arts are the most reliable force for deciding a battle. Just remember, as long as her teammates draw the enemy into her eruption range at the best time, you can leave the rest up to her.
