How do I optimize Fischl's damage as a sub-DPS in Genshin Impact?

Optimizing Fischl as a sub-DPS in Genshin Impact involves understanding her role, mechanics, and how she synergizes with other characters. Fischl excels at dealing consistent off-field Electro damage through her Elemental Skill, Nightrider, and her Elemental Burst, Midnight Phantasmagoria. Her ability to summon Oz, her raven familiar, makes her a versatile and powerful sub-DPS, especially in teams that rely on Electro reactions. HereÔÇÖs a detailed guide to maximizing her potential.

First, letÔÇÖs break down FischlÔÇÖs mechanics. Her Elemental Skill, Nightrider, summons Oz, who deals Electro damage to nearby enemies. Oz remains on the field even if Fischl is swapped out, making him a reliable source of off-field damage. Her Elemental Burst, Midnight Phantasmagoria, transforms Fischl into Oz, dealing AoE Electro damage and refreshing the duration of Oz if he is already on the field. This means you can maintain nearly 100% uptime on Oz, ensuring consistent Electro application and damage.

To optimize FischlÔÇÖs damage, focus on her Elemental Skill and Burst. Prioritize leveling up her Elemental Skill first, as it is her primary source of damage. Her Burst is also important, but it serves more as a way to refresh Oz rather than dealing massive damage itself. Her Normal Attack talent is less important for a sub-DPS build, so you can leave it at lower levels unless you plan to use her as a main DPS occasionally.

For artifacts, the best set for Fischl as a sub-DPS is the Thundering Fury 4-piece set. This set increases Electro damage by 15% and boosts the damage of Electro-related reactions, such as Overloaded, Electro-Charged, and Superconduct, by 40%. If you donÔÇÖt have a full Thundering Fury set, you can use a 2-piece Thundering Fury combined with a 2-piece GladiatorÔÇÖs Finale or ShimenawaÔÇÖs Reminiscence for an 18% Attack bonus. For main stats, prioritize Attack% on the Sands, Electro Damage Bonus on the Goblet, and Critical Rate or Critical Damage on the Circlet, depending on your weapon and substats.

When it comes to weapons, Fischl benefits greatly from bows that increase her Attack, Critical Rate, or Critical Damage. The best 5-star option is the Skyward Harp, which provides high base Attack, Critical Rate, and Critical Damage. For 4-star options, consider The Stringless, which increases Elemental Skill and Burst damage, or the Alley Hunter, which boosts Attack and damage while Fischl is off-field. If you donÔÇÖt have these, the Prototype Crescent or the Rust can also work well, though they are less optimal for a sub-DPS role.

In terms of team composition, Fischl shines in teams that can trigger frequent Electro reactions. Pair her with characters like Bennett for Overloaded reactions, Xingqiu or Mona for Electro-Charged, or Kaeya or Rosaria for Superconduct. Fischl also works well in teams with characters who can trigger reactions quickly, such as Tartaglia or Hu Tao. Her ability to provide consistent Electro application makes her a valuable asset in many team setups.

One common mistake is neglecting FischlÔÇÖs Energy Recharge. While she doesnÔÇÖt need as much Energy Recharge as some other characters, having enough to keep her Burst ready is important for maintaining OzÔÇÖs uptime. Aim for around 130-150% Energy Recharge through substats or an Energy Recharge Sands if necessary. Another mistake is using Fischl in teams where Electro reactions are not beneficial. For example, pairing her with Geo or Anemo characters who donÔÇÖt trigger reactions can limit her effectiveness.

Advanced techniques include timing FischlÔÇÖs Elemental Skill and Burst to maximize OzÔÇÖs uptime. For example, use her Burst immediately after her Skill to refresh OzÔÇÖs duration and keep him on the field longer. Additionally, positioning Oz strategically can help ensure he hits multiple enemies or focuses on high-priority targets. In scenarios with multiple waves of enemies, try to summon Oz at the start of each wave to maintain consistent damage.

In summary, optimizing Fischl as a sub-DPS involves focusing on her Elemental Skill and Burst, equipping her with the right artifacts and weapons, and pairing her with characters who can trigger Electro reactions. Avoid common mistakes like neglecting Energy Recharge or using her in non-synergistic teams. With the right setup, Fischl can be a powerful and versatile sub-DPS, providing consistent Electro damage and supporting your teamÔÇÖs overall damage output.
