"Professor, I'm back. These are souvenirs for you. I'll give them to Dr. Kal'tsit and Amiya later. I got a lot of new data and specimens from the eruption of Siesta's volcano. Does Professor want to come and have a look?"

------------------------------------------------

Upon returning from the trip to Siesta this time, Eyjafjalla put on a protective coat that was a little too big for her, made of a quite old material, and even had a lot of signs of wear and tear on it.

While at work she would carefully tuck away the coat to keep it free of dust, but she would always wear it on field trips to the volcano, regardless of whether dust or hot debris would stain it and she would refuse to wear any other clothes.

"Why such a worn-out protective coat? Why do you have to wear it when you climb the volcano?" her fellow scholars finally couldn't help asking such a question.

Eyjafjalla caressed a yellow burn mark on the cuff, and a few sporadic tears newly added in this investigation:

"This coat is very important to me and I want it to accompany me on every volcano expedition.

"I thought it was a good decision to bring it back. I'll wear it and climb more volcanoes until I reach Una.

"... Because, this is my mother's old protective coat. Wearing it now, it doesn't feel too big anymore."

Eyjafjalla’s alter is an interesting unit. Across this priority guide, the top graded units are almost all DPS units. It takes something truly special for a support oriented unit to shine. Eyja2 is that sort of special where the usual top priorities fall into question… or she would be if not for being ridiculously overtuned. As a general rule, Eyja2 already does her job spectacularly well at SL7, which keeps her overall grades down compared to other meta-caliber units. For those just beginning their journey into Masteries, DPS units should still take priority in spite of Eyja2’s high-end station in the meta.

For those further along and with more resource flexibility, the skill to start with depends on your philosophy as a player. S1 is her most commonly used skill, but her S3 (which is also extensively used) has much better gains. So what to invest in first, the skill you’ll use more often or the gains you’ll get more out of when needed? There isn’t an absolute answer to that! That said, this guide does ultimately have to assign grades, and I favor S3 here. The point is, adjust to your own preferences!

To go into more detail, S1 is her more commonly used skill which aligns with Eyja2’s quality-of-life attribute. Her healing is so ridiculous already that as long as you can survive the wind-up time, no other attention is usually needed regarding healing! However, the Mastery gains are notably poor. The only gain to her normal healing occurs at M3 and it’s a paltry ~7.5% difference. Most of the Mastery gain instead lies in the Elemental healing aspect, but that aspect is already strong, plus best left to her S3 when it’s insufficient. Her S1 is a great skill and any great skill is worth pursuing, but as a matter of priority, you will usually be perfectly fine with it at SL7.

Meanwhile, it’s tempting to call S3 her burst skill compared to S1’s consistency, but a very long uptime and a longer downtime make it unusual compared to other burst skills. Nevertheless, it is by far her most unique application. The global range is the most noticeable aspect, but the healing numbers are absolutely ridiculous as well. While it isn’t as “set and forget” as her S1, the burst outcomes are far better and S3’s Masteries represent much bigger gains than S1s. S3M3 clocks in at around ~17% more HPS during the skill, more than twice S1M3’s gain. Simply put, S3’s Masteries will matter more when you need them.

You can pass on her S2 Masteries, although they might be justified if you personally favor Eyja or are a true end-game maximizer. It’s a good skill, but it’s also the most overtuned. Even at SL7 the shield covers enough Elemental damage to protect against three full triggers of fallout and there is virtually nothing in the game that deals out that much that fast. Investing into the Masteries is simply overkill that’s unlikely to ever be practically useful. Note that S2M3 can allow for 100% shield uptime which might theoretically have some value, but places where that would matter over SL7 or one of her other skills are basically non-existent.
