DendroCatalystMain Damage

TL;DR

Nefer's Skill puts her in a dance state where her Charged Attack becomes a free dash that costs no stamina and spends a dew instead. That Charged Attack does all her work: it hits, it counts as a moon reaction and it hoovers up the seeds your team's blooms left on the ground. She needs a Hydro teammate to make those blooms happen at all.

Rotation

Your Hydro teammate goes first and keeps watering the enemies from off the field while she dances. Each bloom is what refills her.
Skill (E) to charge in and start the dance state, which lasts 9 seconds.
Charged Attack three times. Each one spends a dew and picks up any seeds near her when it lands.
Skill (E) again on the second charge and repeat. Fit Burst (Q) in whenever you have three veils banked.

Abilities

Skill (E)	Charges forward for Dendro damage and starts the dance state, 9 seconds long on a 9 second cooldown with two charges. It also converts every Dendro core already on the field into a seed. On top of that, the party's moon blooms leave seeds instead of cores for the next 15 seconds.
Charged Attack	Ordinarily a stamina-hungry slide. In the dance state, with at least one dew banked, it becomes the free version: no stamina, spends one dew and gathers up the seeds within range of where it lands. Three of them fit in one dance state.
Burst (Q)	Costs 60 Energy, 15 second cooldown. One big Dendro hit in front of her. It spends all her banked veils to hit harder.
Her veils	One per seed picked up. At three of them she gets 100 Elemental Mastery for 8 seconds. They are also what the Burst cashes in.

The one mechanic to understand

The dew is a party bar that fills when anyone triggers Lunar-Bloom (the moon version of Bloom), at most one every 2.5 seconds up to three. Each free Charged Attack costs one, so if the team is not reacting she runs dry and her damage stops. The seeds are what your blooms turn into while she is dancing, in place of the usual Dendro cores. They do not explode and they cannot Hyperbloom, so nobody else gets anything out of them. She picks them up by Charged Attacking near them. Each one is a veil towards her Elemental Mastery bonus and her Burst.

What actually matters

Elemental Mastery. Her damage is moon reaction damage, so Elemental Mastery moves all of it. The passive that speeds up her dew only starts paying above 500 of it.
Hydro on the enemy the whole time she dances. The dew refills one bloom at a time, so the Hydro has to keep coming while she is on the field: an off-field applicator that waters between her dashes, not one splash before she swaps in. When the blooms stop the dew stops. With no dew her Charged Attacks go back to costing stamina.
A second Nod-Krai character. Below the higher Moonsign level she gets no seeds at all, which takes out her veils, her Elemental Mastery bonus and most of her Burst.

Gear

Weapon	Elemental Mastery first, Crit second. Mappa Mare is craftable and gets her going.
Artifacts	4-piece Night of the Sky's Unveiling, the set released with the moon reactions. 4-piece Gilded Dreams is the farmable stand-in, since it is a straight pile of Elemental Mastery.

Sands	Goblet	Circlet	Substats
EM	EM	Crit	Crit / EM

A Dendro damage goblet is worse here, because reaction damage ignores it. No Energy Recharge beyond what turns up: the Burst fills a gap while the dew refills rather than driving her.

Works well with

Hydro

Dendro

Hydro is the requirement, from a character who keeps applying it off the field while she dances. A second Dendro character keeps blooms coming while she dances. One that carries the moon mark covers the Moonsign level at the same time.

Don't bother

Charged Attacks outside the dance state. They eat 50 stamina and none of the good half applies.
Her Normal Attacks. Three Charged Attacks per dance state is what you are there for.
Bringing an Electro character for Hyperbloom. Her seeds cannot trigger it, so the Electro character has nothing to work with while she dances.
Holding the Burst for a bigger cash-in. Three veils is the cap you will normally have, so use it and get back to dancing.
