BarcarolaBuild and Guide

Barcarola is the core of a team that focuses on [Impromptu Incantation], an incantation that deals Mental damage after all allies' cards have been used. What exactly is it? It’s a randomly targeted attack, increasing in power with more hits if you have a high count of [Inspiration] stacks. Each hit is randomly targeted at a random enemy, which can result in very high damage.

[Inspiration] is gained when an ally consumes Eureka (Her Insight I effect). She can also consume Eureka using her skill, “Music of the Heart”, which consumes 2 Eureka. It’s a single-target attack that deals more damage when three or more characters are in [Quartet] (which I will discuss later). It also increases [Impromptu Incantation]'s damage, even more so if you meet the [Quartet] conditions I mentioned earlier.

Her other skill also gives her Eureka. "Cascading Arpeggios" consumes 2 Eureka and is also a single-target attack. Instead of increasing damage, it increases the number of hits that [Impromptu Incantation] will perform, and this increase is further amplified when you have [Quartet], similar to the other skill.

Her ultimate, “Sea Breeze Serenade,” is where [Quartet] is gained. It’s a powerful buff that increases the attack of both yourself and your target's ATK on your team, and grants [Inspiration] after using an Attack Incantation, making them consume 1 Eureka. It also provides a flat Moxie +1 and Eureka +3 when you initially use the buff, making it a strong buff overall.

As you gain stacks of [Inspiration] from [Eureka], you strengthen the attack potential of your [Impromptu Incantations], not only through the sheer number of hits but also by increasing its critical rate and damage. The more you use it in a round, the higher its crit rate/DMG becomes, thanks to her Insight III. Essentially, you just gain passive damage by having Eureka characters in your team, which as suggested means you do need characters that help her with this in order to achieve high damage. It’s fairly easy to use if you have the right team.

For her to function, you'll likely need characters like Matilda (I know you're making the Pikachu shocked face right now) and someone like Voyager. Both of these characters were buffed with [Euphoria] and now directly correlate their skills with [Impromptu Incantation] teams. While that’s great, Euphoria costs a lot of resources. So, not only is she a 6-star unit you need to pull for, which is core to the team, but you also have to invest a lot of resources into her allies. Even her best teammates, who don’t require or have Euphoria, are still mostly 6-stars, which is still costly to invest in or even pull for in the first place.

While any [Eureka] character will likely benefit her, if you want to utilize the effects of a character that consumes their own [Eureka], she might not be the best choice. This is because that character will lose their Eureka really fast when paired in a team with her and likely unable to activate their own effects.

However, if you’re willing to invest, Barcarola offers an exciting new playstyle with impressive damage potential. Once set up, you’ll have a character with high passive damage, requiring minimal effort in actual battle.

Portrays

Her portrays are honestly quite good, so it's unfortunate that she's a 6-star, but you don't necessarily need it.

Portray level 2 will increase [Impromptu Incantation] hit rate and crit damage by 15%, which is really good, and level 3, which increases [Impromptu Incantation] hits by 2, is also beneficial. Level 4 is a simple damage buff, and level 5 is also really strong as it allows you to gain Inspiration faster. You don’t need any of it if you have the right teammate, but it certainly helps if you have the budget for it.
