How do I optimize energy recharge for Collei in Genshin Impact?

Optimizing energy recharge for Collei in Genshin Impact is essential to ensure she can consistently use her Elemental Burst, which is a key part of her role as a Dendro support or sub-DPS. Energy recharge (ER) is a stat that determines how quickly a character can regenerate energy particles, which are needed to charge their Elemental Burst. For Collei, who relies on her Burst to apply Dendro and trigger reactions, having sufficient ER is crucial. HereÔÇÖs a detailed guide on how to optimize her energy recharge.

First, letÔÇÖs understand the mechanics. ColleiÔÇÖs Elemental Burst, "Trump-Card Kitty," deals AoE Dendro damage and creates a field that continues to deal Dendro damage over time. To use this ability frequently, you need to ensure she has enough energy to cast it. Energy particles are generated by using Elemental Skills, defeating enemies, or through certain weapon and artifact effects. ColleiÔÇÖs Elemental Skill, "Floral Brush," generates Dendro particles, but the amount may not always be enough, especially if she is not on the field often. This is where energy recharge comes into play.

To optimize ColleiÔÇÖs energy recharge, start by focusing on her artifacts. The best artifact set for her is the "Emblem of Severed Fate," which increases energy recharge and boosts her Elemental Burst damage based on her ER. Aim for an ER sands as the main stat, and prioritize ER substats on other pieces. If you donÔÇÖt have a full Emblem set, you can use a 2-piece Emblem set combined with a 2-piece "The Exile" or "Scholar" set for additional ER. The main goal is to reach at least 180-200% ER, which should allow her to use her Burst consistently.

Next, consider her weapon. The best weapon for energy recharge is the "Favonius Warbow," which generates energy particles when you score a critical hit. This weapon synergizes well with ColleiÔÇÖs role as a support, as it helps her and her teammates gain energy. If you donÔÇÖt have the Favonius Warbow, the "Sacrificial Bow" is another good option, as it has a chance to reset her Elemental Skill cooldown, allowing her to generate more particles. For free-to-play options, the "Recurve Bow" or "End of the Line" can also work, though they provide less ER.

Team composition is another important factor. Collei works best in teams that can generate energy particles for her. Characters like Fischl, Raiden Shogun, or Kuki Shinobu are excellent teammates because they generate energy particles frequently and can trigger elemental reactions with Dendro. For example, pairing Collei with Fischl allows for consistent Electro-Dendro reactions, which generate additional energy particles. Additionally, having another Dendro character like Dendro Traveler or Tighnari in the team can help with energy generation through Dendro resonance, which increases energy recharge.

When building Collei, avoid the mistake of neglecting her ER in favor of other stats like attack or critical rate. While these stats are important for damage, ColleiÔÇÖs primary role is to support her team with Dendro application, and her Burst is key to this. Without sufficient ER, she will struggle to use her Burst consistently, reducing her effectiveness. Another common mistake is not using her Elemental Skill frequently enough. Make sure to swap to Collei and use her Skill whenever itÔÇÖs off cooldown to generate particles.

For advanced optimization, consider using Collei in a rotation where she can catch her own particles. This means using her Skill and then immediately switching to another character to funnel the particles to her. This technique maximizes the energy she gains from her Skill. Additionally, if you have her at Constellation 2, her Burst duration is extended, making it even more important to have high ER to maintain uptime.

In specific scenarios, such as the Spiral Abyss, ColleiÔÇÖs energy needs may vary depending on the enemies and team composition. For example, against enemies that drop fewer energy particles, you may need to increase her ER further. In contrast, in teams with multiple energy-generating characters, you might be able to reduce her ER slightly.

In summary, optimizing ColleiÔÇÖs energy recharge involves focusing on her artifacts, weapon, and team composition. Aim for at least 180-200% ER, use energy-generating weapons like the Favonius Warbow, and pair her with teammates who can help generate energy. Avoid neglecting her ER in favor of other stats, and use advanced techniques like particle funneling to maximize her energy gain. With these strategies, Collei will be able to consistently use her Elemental Burst, making her a valuable support in any team.
