Water. Earth. Fire. Air. Also, Electricity and Ice, for some reason. Long ago, the six Genshin Impact Elements existed together in harmony. Then everything changed when the game introduced Dendro. Now there are more elemental reactions to work with, leaving many confused Genshin Impact players asking how do Dendro Reactions work.
Suffice it to say, the Dendro Element in Genshin Impact added a lot of new dynamics to the gameโs combat. It can pair with most other elements to create unique reactions that can enable builds and even help you ease into more of the gameโs harder content.
To familiarize yourself with how Dendro Reactions work in Genshin Impact, hereโs a somewhat fun and simple primer.
Bloom (Dendro + Hydro)

First up is Bloom which is one of the more straightforward Dendro Reactions. Bloom doesnโt exactly create an immediate debilitating or amazing damage interaction. Instead, each Bloom reaction creates a Dendro Core, which is vital for accessing the more intricate, three-element reactions in Genshin Impact.
Itโs also worth noting that there are only five Dendro Cores that can be active on the field, so use them wisely.
If more Dendro Cores are created past the limit, the older ones will explode. Dendro Cores also have a set duration of six seconds, and if this duration ends, the Dendro Core will also explode. Both scenarios for Dendro Core explosion deal Dendro damage.
If you want to increase Dendro Core explosion damage, the character who created the Dendro Cores must have Elemental Mastery boosts.
Hyperbloom (Dendro + Hydro + Electro) or (Dendro Core + Electro)

Now comes the fun part with Dendro Cores. If a Dendro Core gets hit or combined with the Electro Element, it will trigger Hyperbloom.
The Dendro Core is consumed instead of exploding and will release Sprawling Shots. These Sprawling Shots are homing projectiles that deal Dendro damage.
Itโs a bit tricky to boost Sprawling Shotsโ damage since the damage increase will come from the Electro character who triggered Hyperbloom. Likewise, Elemental Mastery primarily affects Hyperblooms damage. Moreover, needing a Hydro character or source can make it a bit challenging.

Burgeon (Dendro + Hydro + Pyro) or (Dendro Core + Electro)

Burgeon is one of the many creative actions you can trigger by toying with Dendro Cores. Youโll just need to hit a Dendro Core with Pyro damage.
Burgeon will then cause a fairly large explosion that deals area Dendro damage. Itโs great for clearing up packs of enemies using your dedicated Pyro DPS.
Thatโs because Burgeonโs Dendro explosion damage will depend on the source of the Pyro damage for its scaling. Elemental Mastery can increase the damage amount. This explosion also has the potential to stagger some small enemies, making it somewhat useful for crowd control.
Catalyze / Quicken (Dendro + Electro)

When you combine Dendro and Electro, you get the initial Catalyze reaction which will create the Quicken Aura.
Itโs displayed as a green spark around the enemy or the target. This kind of reaction does not damage the enemy (apart from their respective elementsโ damage). Think of it as a debuff marker for the enemy.
The Quicken Aura also has a limited duration which depends on hidden factors, but the typical number is around 11 seconds.
This should allow plenty of time to trigger its accompanying or combo reactionโฆ
Aggravate (Dendro + Electro + Electro) or (Quicken + Electro)

So what do you do with a Quickened enemy or an enemy inflicted with the Quicken Aura? You hit them again with Electro damage.
Doing so will trigger Aggravate, which is practically a big damage increase for the Electro Element. Any Quickened enemy hit with Electro damage will take an increased amount of the said damage type.
Again, the damage boost for Aggravate will depend on the Electro character’s Elemental Mastery.
Unlike other three-element reactions in Genshin Impact, Aggravate is relatively easy to perform since it only requires two elements or perhaps even just two characters, depending on their roles or their potential for damage.
Moreover, itโs important to remind players that the sequence has to be correct (Dendro + Electro + Electro) and not the other way around or with Dendro as the final element, or you might get a different Elemental Reaction.
Spread (Dendro + Electro + Dendro) or (Quicken + Dendro)

If you happen to hit a Quickened enemy with a Dendro character instead of Electro, you will get Spread as a reaction instead.
Spread works similarly to Aggravate, and the Quickened enemy or target will take increased Dendro damage if hit with Dendro attacks. As always, you can further increase the damage Spread will inflict using Elemental Mastery.
Likewise, itโs also easy to perform despite being a three-element reaction since youโll just be switching back to the original Dendro applicator or your dedicated Dendro DPS in order to deal this kind of damage and Elemental Reaction.
You will still need to switch twice, however, making it a bit more cumbersome to apply compared to Aggravate, especially if you mess up your character switching and the cooldown interferes.
Burning (Dendro + Pyro)

Burning has actually been available in the game even before Dendro became available as a playable element. Dendro mage enemies like those Hilichurl shamans can trigger it quite frequently with nothing but burning grass and their usual Dendro attacks.
The results, as some players might recall, are devastating or alarming since Burning deals quite a worrying amount of damage over time under the Pyro Element.
The damage depends on whoever triggers the reaction, regardless of which Element goes first. Again, Elemental Mastery can increase the effect and intensity of damage over time caused by Burning.
Only Triple-Element Reactions Require the Right Sequence

You donโt have to worry about dual-element reactions since either element can go first or last. It will still result in triggering the corresponding Elemental Reaction.
Triple-element reactions, on the other hand, require a specific sequence where the third or final element to be applied needs to be precise.
In the case of Aggravate, Spread, Burgeon, or Hyperbloom, youโll need to be strict with the sequence, making them a bit harder to trigger in the chaos of Genshin Impact combat with all the colorful Dendro Reactions.
