How do I build a team around Nilou's bloom reactions in Genshin Impact?

Building a team around Nilou's Bloom reactions in Genshin Impact requires a deep understanding of her unique mechanics and how they interact with other Hydro and Dendro characters. Nilou's passive talent, "Court of Dancing Petals," modifies the Bloom reaction when your team consists only of Hydro and Dendro characters. This modification creates Bountiful Cores instead of regular Dendro Cores, which deal more damage and explode faster. To maximize this effect, you need to focus on team composition, artifact choices, and combat strategies.

First, let's break down the mechanics. Bloom is an elemental reaction that occurs when Hydro meets Dendro, creating Dendro Cores. These cores explode after a short delay, dealing AoE Dendro damage. Nilou's passive talent enhances this reaction, turning Dendro Cores into Bountiful Cores, which have a larger AoE and deal more damage. However, this enhancement only works if your team is exclusively Hydro and Dendro characters. This means you cannot include characters of other elements like Pyro, Electro, or Cryo, as they will disable Nilou's passive.

For team composition, you need at least two Hydro and two Dendro characters. A common setup includes Nilou as the main Hydro enabler, another Hydro character for energy generation and healing, and two Dendro characters for consistent Dendro application. For example, you could use Nilou, Kokomi or Barbara for healing, Nahida for Dendro application and EM buffs, and Collei or Dendro Traveler for additional Dendro support. This setup ensures you have enough Hydro and Dendro application to trigger Bloom consistently.

Artifact choices are crucial for maximizing Bloom damage. For Nilou, prioritize HP% main stats on her artifacts, as her Bountiful Cores scale with her max HP. The 2-piece Tenacity of the Millelith and 2-piece Heart of Depth sets are ideal for increasing her HP and Hydro damage. For Dendro characters like Nahida or Dendro Traveler, focus on Elemental Mastery (EM) to boost the damage of the Bloom reaction. The 4-piece Deepwood Memories set is excellent for reducing Dendro resistance, while the 4-piece Gilded Dreams set can provide additional EM.

Weapon choices also play a significant role. For Nilou, the Key of Khaj-Nisut is her best-in-slot weapon, as it provides HP% and boosts team EM based on her max HP. If you don't have this weapon, the Primordial Jade Cutter or the Festering Desire are good alternatives. For Dendro characters, weapons like the Sacrificial Fragments or the Mappa Mare can increase EM and enhance Bloom damage.

In combat, the key strategy is to maintain consistent Hydro and Dendro application. Start by applying Dendro with Nahida or Dendro Traveler, then switch to Nilou to trigger Bloom with her Hydro attacks. Use Kokomi or Barbara to heal and apply additional Hydro, ensuring that Dendro Cores are constantly being created. Since Bountiful Cores explode faster, you need to position your characters carefully to avoid taking damage from the explosions.

One common mistake is neglecting the importance of EM on your Dendro characters. Since Bloom damage scales with the EM of the character triggering the reaction, it's essential to stack EM on your Dendro supports. Another mistake is including characters of other elements, which disables Nilou's passive and reduces the effectiveness of Bountiful Cores.

Advanced techniques include timing your abilities to maximize Bloom triggers. For example, using Nahida's Elemental Skill to mark enemies and then switching to Nilou to trigger multiple Blooms at once. You can also use Kokomi's Elemental Burst to apply Hydro in a wide area, ensuring that all marked enemies are hit by Bloom reactions.

In summary, building a team around Nilou's Bloom reactions requires careful planning and optimization. Focus on a Hydro-Dendro team, prioritize HP% for Nilou and EM for Dendro characters, and use artifacts and weapons that enhance these stats. Maintain consistent elemental application in combat, and avoid common mistakes like neglecting EM or including characters of other elements. With the right setup, Nilou's Bloom team can deal massive AoE damage and dominate in both overworld and Spiral Abyss content.
