Hyperbloom: Nahida Marks, Xingqiu Wets, Kuki Triggers

Nahida's skill marks the camp. Hold it when the enemies are packed, tap it when you are picking one elite. Xingqiu's burst fires rain swords when someone normal-attacks, and those swords apply Hydro onto the Dendro. The mix creates Dendro cores. Kuki's skill, the Sanctifying Ring, follows the active character and ticks Electro. An Electro tick that hits a core turns it into a homing Hyperbloom. If the ring is down, cores sit on the ground and then burst as a smaller Dendro explosion. That is not the team you built.

Hyperbloom's damage uses the Electro character's level and Elemental Mastery. It does not use her attack, her crit, or Nahida's crit. A Kuki in an attack build with a crit circlet will create the same number of blooms and watch them hit like wet paper. Level her to 90 before you level a five-star weapon on someone else. The reaction looks up her level on a curve that still moves between 80 and 90.

Nahida can stay and normal-attack. Her attacks keep Dendro on the mark, and the normal attacks call Xingqiu's swords. Kuki does not need to be the one attacking. Her ring follows whoever is active, so Nahida on the field still triggers Hyperbloom as long as the ring is up. Refresh Nahida's mark when a new enemy walks in without one. Refresh Kuki's ring when it expires, even if you are mid-combo. A dead ring is a rotation that is over.

The fourth slot is another Hydro if Xingqiu cannot fund his burst, or a shielder if Nahida is getting interrupted and dropping the normal attacks. Zhongli works if his pillar is not eating the cores' auras. Put the stele off to the side. A second Electro who also hits the cores will steal some of them. One trigger is cleaner. Raiden's skill can be that trigger instead of Kuki, with the same mastery and level rules, but then you do not also build her burst set.

Kuki wears as much Elemental Mastery as you can put on the flower, feather, sands, goblet, and circlet. The flower and feather still need to be the right set pieces with mastery substats, because their main stats are fixed. Give her an Elemental Mastery sword. Nahida wears Deepwood if nobody else does, so Dendro resistance drops for the blooms that still deal Dendro. Xingqiu wears Emblem and Sacrificial Sword so the rain does not stop. Do not farm Marechaussee for Kuki. She does not crit the bloom.

Cast order in a room: Nahida skill, Xingqiu skill and burst, Kuki skill, then Nahida normal attacks. Burst Nahida if the party mastery share will help her own Tri-Karma while she is the one on the field. The Hyperbloom number still belongs to Kuki.
