What it costs to finish this character

1,350

resin, level 1 → 90 and all three talents to 10

2,072,500

mora

days at a minimum, if you spend nothing else

Ascension alone: 760 resin (boss drops only) · talents alone: 590 resin.

Talent books: Elysium. To show the days this domain opens, add its row to the rotation table — the six regions already in it are there, and this one is not, so no day is claimed for it.

A Crown of Insight is needed for the tenth level of each talent, and crowns are not farmable at any resin price — they come from events.

Materials and mora above are exact, straight from the game’s own tables. The resin figure and the day count divide by an average drop per run, which the game does not publish — they are a community-measured mean, not a promise.

Musecatcher

Aino throws a Musecatcher forward, dealing Hydro DMG and dragging her along behind it. When the dragging stops, Aino deals AoE Hydro DMG to nearby opponents.

Holding the Skill will cause it to behave differently.

Hold

Enter Aiming Mode to adjust the Musecatcher's throwing direction.

This DMG is considered Elemental Burst DMG. This effect can be triggered once every 5s.

Weapons and artifacts

UNSURE This is not a tier list and not community guidance — this product has neither. It is a mechanical shortlist, and the rule is printed so you can check it: Claymores of 4★ and above whose secondary stat is one this character’s ascension stat scales with, ordered by base attack at level 90. Weapon passives are not weighed, because a passive is an effect and not a number.

Weapons of the right type and stat
Weapon	Rarity	Base ATK at 90	Secondary stat
Wolf's Gravestone	5★	608	ATK%
The Unforged	5★	608	ATK%
Royal Greatsword	4★	565	ATK%
Prototype Archaic	4★	565	ATK%
Mailed Flower	4★	565	Elemental Mastery
Fruitful Hook	4★	565	ATK%
Earth Shaker	4★	565	ATK%
Blade of Atonement	4★	565	ATK%

Sets whose two-piece bonus raises this character’s Hydro damage or the stat they ascend into
Set	Two-piece	Four-piece
Heart of Depth	Hydro DMG Bonus +15%	After using Elemental Skill, increases Normal Attack and Charged Attack DMG by 30% for 15s.
Nymph's Dream	Hydro DMG Bonus +15%	After Normal, Charged, and Plunging Attacks, Elemental Skills, and Elemental Bursts hit opponents, 1 stack of Mirrored Nymph will be triggered, lasting 8s. When under the effect of 1, 2, or 3 or more Mirrored Nymph stacks, ATK will be increased by 7%/16%/25%, and Hydro DMG Bonus will be increased by 4%/9%/15%. Mirrored Nymph stacks created by Normal, Charged, and Plunging Attacks, Elemental Skills, and Elemental Bursts exist independently.

To turn this into a real recommendation section, add a build dataset — per character, the weapons and sets a community source actually recommends, with the rotation each assumes. Nothing in the game’s published data contains that judgement, and a ranking invented here would be indistinguishable from a researched one, which is why there is not one.

Teams

To build a team section, add team data. Which characters go together is judgement about rotations, energy and shielding that this product does not receive and will not guess at.

What is published is the reaction chart. Hydro takes part in:

Vaporize with Pyro
Frozen with Cryo
Electro-Charged with Electro
Bloom with Dendro
