Bloom, Burgeon and Hyperbloom in Genshin Impact: Complete Reaction Guide

Bloom, Burgeon and Hyperbloom are the core Dendro-based reactions that fundamentally reshaped Genshin Impact’s combat system. These reactions revolve around the creation and transformation of Dendro Cores—temporary explosive objects that enable powerful AoE and single-target damage. With strong scaling, flexible team-building options and reliable output, Bloom reactions rank among the most influential mechanics in the game. Understanding their behavior, scaling principles and strategic uses is essential for optimizing any Dendro composition.

Bloom: The Foundation of Dendro Core Reactions

Bloom occurs when Hydro and Dendro interact. This reaction generates a Dendro Core on the ground, which persists for a short time before exploding. The explosion deals AoE Dendro damage that scales purely with character level and Elemental Mastery, making Bloom extremely accessible for newer players and highly efficient for end-game teams.

Bloom on its own is powerful in multi-target combat but can be difficult to control in chaotic fights because the cores explode after a delay. This delayed detonation can damage the active character if they are too close, requiring careful positioning. However, Bloom serves as the foundation for two of the strongest modern reactions: Burgeon and Hyperbloom.

Hyperbloom: Electro-Triggered Single-Target Damage

Hyperbloom is triggered when Electro is applied to a Bloom-created Dendro Core. Instead of exploding in place, the core turns into a homing projectile that automatically seeks out a target and deals significant single-target Dendro damage. This mechanic eliminates positioning concerns and makes Hyperbloom one of the most consistent reactions in the game.

Hyperbloom scales exclusively with Elemental Mastery and character level, allowing Electro characters to build pure EM for maximum damage. Because Hyperbloom projectiles track enemies, they bypass movement and targeting issues, performing exceptionally well in Spiral Abyss where enemies often dash or teleport. Hyperbloom teams also require minimal mechanical execution, making them highly accessible.

Burgeon: Pyro-Triggered AoE Explosions

Burgeon occurs when Pyro interacts with a Dendro Core. This reaction transforms the core into a powerful AoE explosion that deals increased Dendro damage in a wide radius. Burgeon is ideal for clearing large enemy packs or waves in domains due to its strong area coverage.

However, Burgeon cores explode immediately and can damage the active character. This self-damage requires careful team-building, often including shielders or off-field Pyro appliers who can safely trigger Burgeon without putting the active character at risk. Despite the danger, Burgeon remains one of the strongest reactions for players who prefer fast-paced, explosive combat.

Scaling Rules for Bloom, Hyperbloom and Burgeon

All three reactions fall under transformative scaling, meaning they do not rely on Attack, Crit Rate or Crit Damage. Instead, their output depends on character level and Elemental Mastery. This makes Bloom-based teams extremely artifact-friendly and less dependent on perfect gear.

Because Elemental Mastery heavily influences these reactions, characters built as dedicated triggers—usually Hydro, Electro or Pyro units—often stack EM to maximize detonation output. This creates flexible team compositions where supports or healers can still contribute significant damage through EM-based reactions.

Strengths of Bloom-Based Teams

Bloom, Burgeon and Hyperbloom offer strong advantages. They scale with EM, making them easy to build and efficient from early game to endgame. Their damage ignores Crit scaling, enabling consistent damage output regardless of artifact RNG.

Hyperbloom provides excellent single-target consistency due to its homing behavior. Burgeon delivers some of the strongest AoE potential in the game. Standard Bloom offers persistent zone damage in multi-target encounters. These strengths make Bloom reactions viable across all content types, including Spiral Abyss.

Weaknesses and Challenges

Bloom cores can harm the player, especially in Burgeon-centric teams. Managing positioning and shielding is critical for survival. Another limitation is aura stability: Bloom teams require consistent Hydro and Dendro application, and misaligned rotations can reduce reaction uptime.

Additionally, certain enemies may resist or avoid AoE damage, reducing the effectiveness of Burgeon or Bloom. Hyperbloom, while generally reliable, may struggle against targets that disappear or burrow temporarily.

Team Compositions for Bloom Reactions

Bloom teams typically include a Hydro applier, a Dendro applier and a reaction trigger (Electro for Hyperbloom or Pyro for Burgeon). This structure ensures stable core generation and consistent detonations. Healers or shielders are often added to support survivability, especially in Burgeon teams where self-damage is common.

Hyperbloom teams excel with fast Electro appliers who can trigger cores repeatedly without field time. Burgeon teams benefit from characters who apply Pyro off-field to avoid damage while still detonating cores. Standard Bloom teams use strong Hydro-Dendro pairing to overwhelm enemies with AoE explosions.

Where Bloom, Burgeon and Hyperbloom Perform Best

Hyperbloom excels in both single-target and mixed encounters, making it ideal for Abyss floors with dangerous bosses or teleporting enemies. Burgeon shines in wave-based content where enemy density is high and repeated AoE detonations clear rooms quickly. Bloom itself works well in open-world farming, exploration and multi-enemy domains.

Across all content types, Bloom reactions provide efficient, consistent and flexible damage options that elevate team performance with minimal investment.

Conclusion

Bloom, Burgeon and Hyperbloom represent some of the most powerful and versatile reactions in Genshin Impact. Their strong scaling, ease of use and wide applicability make them core components of modern team-building. Whether players prefer massive AoE detonations, precise single-target homing attacks or simple Bloom setups, Dendro Core reactions offer a complete toolkit for dominating any battle.
