Bloom is an elemental reaction in Genshin Impact that is triggered when Dendro and Hydro meet. See how to trigger Bloom, best characters to trigger it, and the best teams for this elemental reaction!

What is the Bloom Reaction?

Reaction Between Dendro and Hydro

Bloom is the elemental reaction when Dendro meets Hydro, or vice versa. Any unit that has an aura of either of the two elements will immediately result to Bloom!

Some Bouncy Mushrooms that are commonly endemic in the Sumeru Rainforests can spawn Dendro Cores when hit with Hydro!

How to Trigger Bloom

Combine Dendro and Hydro

To trigger Bloom, simply combine Dendro and Hydro in any order. Any unit with an aura of either element that is hit by Dendro or Hydro, will spawn Dendro Cores that explode after a certain duration!

What are Dendro Cores?

Dendro Cores are the resulting reaction between Dendro and Hydro that look like green fruits spawning where Bloom happened. Dendro Cores are indiscriminant when it comes to dealing damage, in that it inflicts damage to both enemies and allies!

Trigger Dendro Cores with Pyro and Electro

Dendro Cores are reactive when hit by Pyro and Electro, which result to Burgeon, and Hyperbloom, respectively. This means Dendro Cores (except Bountiful Cores) created through Bloom are required to create those reactions!

Best Characters To Use for Bloom

Nilou

Nilou is a highly-niche character who shines best in Bloom teams, due to her first ascension passive. And while it limits the team to Dendro and Hydro units only, the Bountiful Cores created from this passive are bigger, have larger AoEs, and explode instantly!

When to Use Nilou in Bloom

When you have a good Hydro or Dendro unit who can provide heals and shields for the team.

When you want consistent Dendro damage with large AoE.

When you're going against enemy mobs that are widely-scattered.

Nahida

It's not an understatement to say that Nahida is the best Dendro unit in the game right now. She has great Dendro application, impressive on- and off-field capacity, and she scales with EM, making her a good choice in most team compositions, including Bloom!

When to Use Nahida in Bloom

When you need an excellent Dendro driver or applicator who can sustain almost 100% Bloom uptime.

When you want to further reward triggering Dendro-based reactions, such as Bloom.

When you have a Hydro unit who can keep-up with Nahida's Dendro application.

Kaveh

Kaveh has recently (and indirectly) buffed Bloom teams because of his Elemental Burst, which increases the Dendro Cores' damage by a certain amount when they explode, while infusing his attacks with Dendro.

Kaveh's A1 passive enables him to heal the damage taken from core explosions thrice the amount of his EM, making him a really good fit for Bloom teams!

When to Use Kaveh in Bloom

When you have well-built off-field Hydro and Dendro units who can consistently spawn Dendro Cores.

When you want to further increase, and maximize Dendro Core damage without suffering from friendly-fire.

When you want an aggressive DPS who has Dendro-infusion on both normal and charged attacks, while detonating Dendro Cores around your character.

Baizhu

Baizhu is an excellent Dendro support who can provide self-sustaining shields and heals that can mitigate Dendro Core explosions.

But what makes Baizhu a good choice for Bloom (and other Dendro-based) teams is his fourth ascension passive that increases the DMG of Dendro-reactions!

When to Use Baizhu in Bloom

When you need good sustain thru heals, and shields for your active character.

When you want an excellent Dendro-reaction buffer, who scales off HP-stats.

Baizhu Rating and Best Builds

Kokomi

Kokomi has impressive Hydro application thanks to her Elemental Skill, which makes her viable for Bloom. Also, her top-of-the-line healing mitigates the self-inflicted damage of Dendro Cores, ensuring that the whole team stays alive throughout the entire rotation!

When to Use Kokomi in Bloom

When you want to sustain the team with impressive heals, and to mitigate HP loss from Dendro Core explosions.

When you want a Hydro Applicator who can decently apply the element in a wide AoE for a decent amount of time.

When you have a Hydro unit who can keep-up with Nahida's Dendro application.

Kokomi Ratings and Best Builds

Xingqiu

Xingqiu on his own is an extremely impressive and flexible Hydro unit who can effectively apply Hydro consistently off-field, while providing damage resistance, and decent heal for the team.

This makes him a staple for most Bloom teams, and other transformative teams that require Hydro!

When to Use Xingqiu in Bloom

When have a Dendro unit who relies primarily relies on normal attacks to trigger Bloom.

When you want to fortify the shield of your Dendro or Hydro unit to withstand damage from enemies, and Dendro Cores.

When you want an excellent Hydro unit against a single enemy to constantly proc Bloom.

Best Teams for Bloom

Nahida-Kokomi Bloom Team

Main-DPS	Support	Drivers
Kokomi	Nilou	Nahida	Traveler (Dendro)

In this Bloom team, Kokomi is the one who primarily triggers Bloom with Nahida, and the Traveler. To run this team, you must sacrifice a portion of Kokomi's healing capabilities by loading her with a full-EM set.

Don't worry about tanking core explosions, as you'll have plenty of room to run around, as this team has tremendous AoE potential! Also, you can replace Dendro MC with Collei for a wider Dendro application with longer reach!

Nilou-Kaveh Bloom Team

Main-DPS	Support	Sub-DPS
Kaveh	Baizhu	Nilou	Yelan

This Nilou-Kaveh Bloom team takes Dendro Core damage to the next level without sacrificing the team's defensive capabilities. Baizhu, Kaveh, and Nilou reward triggering Bloom, while the Hydro Resonance increases the team's HP to further their damage and buffs!

Kaveh acts as the detonator of the team by slotting him as the main DPS, while Yelan and Nilou append Kaveh's Dendro-infusion, to consistently trigger Bloom. With Nilou, Kaveh, and Baizhu, present, all core explosions will surely pack a punch!

Nilou-Nahida Bloom Team

Main-DPS	Support	Sub-DPS
Kaveh	Baizhu	Nilou	Nahida

A variant of the Nilou-Kaveh team, this comp maximizes Dendro Core explosion damage by replacing Yelan with Nahida. This triple-Dendro team ensures that cores have 100% uptime, guaranteeing that Kaveh can constantly detonate them!

Nilou-Ayato Bloom Team

Main-DPS	Support	Sub-DPS
Nilou	Baizhu	Nahida	Ayato

This Nilou-Ayato Bloom team is a far-reaching team that can whittle out enemies' HP in a wide AoE. Ayato and Nahida offer great Hydro and Dendro application thru their bursts and skills, while Baizhu provides sustain for your active character.

Nilou primarily uses her Sword Dance Form to infuse her normals with Dendro, which can be buffed by Ayato's and Baizhu's burst!
