Item Story

The longbow once used by the Watatsumi shrine maiden Mouun,
It shines as pure white as the seafoam at the tip of a moonlit wave.

The shrine maiden was friends with the monsters of distant seas, and together they did battle against the thundering clouds for the sake of Watatsumi's transient dream.
The bosom companions rode the waves as one, looming ever in the spray created by the bows of ships...
On and on they went, pursuing the path of no return that Watatsumi was now on until they went together to the land of their tragic obliteration.

"Perhaps it is true that Lord Watatsumi Omikami's war was doomed from the start."
"But as long as we leave these memories behind, as long as we sow the seeds of sacrifice, this might all be worth it."

The songs of the past eulogize the tacit bond she shared with "Umigozen" as twins born of Watatsumi,
And depict them, bow drawn and spear raised, bathing in the wave-spray of a ship's bow...
These distant songs recount how she rode with Touzannou upon the back of a sea creature in the night,
The broken tomorrows she whispered of, gently and mournfully, into the hero's ear...

In yet peaceful days, the twins once sang in chorus with the great whale of the deep sea,
Telling of dismal days spent in the depths and the dark ever-night, and of Omikami and the radiant jade branches.
She once frolicked with that reckless young man, whose only strength was his strength...

"Once I bring that legendary Great Tengu's mask back, you have to keep our promise and finish that business."

"Sure, and if you're still so full of crap then, I'll get a whale to raise a wave large enough to wash that potty mouth of yours clean."

    Sara burst build BIS for a 4 stars weapon.
    Literally the only difference to alley hunter is this weapon got 2x alley hunter dmg bonus (80% for this bow vs 40% for alley hunter). For fischl alley hunter still better since you will use oz a lot more instead of fischl burst dmg.

    Is my math wrong or is the maximum bonus currently unobtainable? (it’d need like 333 energy but with 3 80E and Raiden’s 90E you’d still sit at 330. Though of course it might be a safety measure for future characters perhaps)

      It’s just to round it up so it doesn’t look odd. With a team like Ayaka + Jean + Raiden, Kujo Sara is able to get the maximum buff (79.2% at R5 or 39.6% at R1).

        Pretty sure it could be decent for the Morgana team comp. Not saying its the BiS, but the base atk is 565 and she would get a 28.8% burst dmg bonus. Most of Ganyu’s dmg is loaded into her burst. And since Mona has TTDS, this bow’s extra base atk over some other options could give it a bit of an edge.

          Yep, Morgana team this is good, as in Morgana Ganyu uses 4p Blizzard, this ult dmg bonus will be good

      It doesn’t buff the whole party, It uses the energy costs of the party’s burst to buff the holder of the weapon.

    Is this craftable? I see a claymore and polearm like this bow, so I guess there would be a new set of craftable weapon.

      With how strong these are I doubt they’ll be craftable. Most likely they’ll be limited gacha weapons.
