The Sea Tank Overview
The Sea Tank build is using Merulina. Merulina is her K-drive that she uses to gain mobility, but it also gives damage reduction and scales really hard on strength. Merulina doesn't care about duration at all since, once Merulina is activated, it only has a flat cost and no drain per second. The other great thing about Merulina is that it gives [Yareli] another health bar to use. The other great thing about this build that she does a lot of damage since the build consists of a lot of strength. It also uses the fourth ability, Ripetide, which has no duration for the explosion, only range and strength.
Important Mods
For this build that are important is the Umbra [Intensify], [Fleeting Expertise], [Transient Fortitude], [Blind Rage], [Adaptation], and [Stretch] (The polarize for [Stretch] was used for prime [Flow], but once [Fleeting Expertise] is in. The build isn't too heavy for energy)
The reason for these to be important is because [Yareli] wants all the strength she can get for Merulina, and she wants the damage to go as high as it can go for Ripetide.
Polarizing
Polarizing can be difficult, but for this one. The polarizing that are staples is having Two Marduai, one Vazarin, and two naramon. This allows flexibility and not just putting in random polarizing and finding out that the thing that got polarize messes with another build.
Do I have to Polarize for Umbra?
No, that is optional. It's not worth it if it isn't going to have another umbra in the slot.
Aura Mod
The aura mod [Corrosive Projection] doesn't hurt to have, but it can be forma with an aura forma where any aura mods can be used. I just like the reduce armor because its very nice for tanky enemies and good for higher level enemies and steel path, in my opinion.
Substitution Mods
If you don't want to build for mods that has to be four or five formas and want a cheap, but reliable build. Here it is:
[Blind Rage] can be replaced for [Intensify]
[Transient Fortitude] can be replaced for [Continuity]
[Fleeting Expertise] can be replaced for [Streamline]
[Adaptation] can be used for any survivability mod like [Redirection], [Vitality], or even [Vigor].
Umbra [Intensify] can be replaced with any choice, but if you own a [Blind Rage], than the umbra can be taken out for [Intensify].
Umbra [Vitality] is a free slot for anything.
In Conclusion
Yareli is a very strong frame and is pretty easy to get the hang of after a bit of practice on the K-drive like ability, but once figured out. She can be extremely tanky, thanks to Merulina, and do lots of damage thanks to Ripetide. I hope you all enjoy the build and if there is anything about this guide. Let me know. I love to read some feedback and what your thoughts can be.
