Chasca Build Guide

Without Amplifying Reactions:

Chasca - Iansan - Durin - Nicole

This is Chasca’s best team DPS wise at C0. There are several supports that can slot into any of these slots, though you need at least 2 different Elements generally. Examples include Bennett and Fischl, but even units like Chevreuse can be good.

If using Durin or Nicole, you would ideally use them with the other due to their excellent synergy and being the only two Pyro Hexerei units. Using Fischl instead will shift Chasca into more of an Electro carry.

Example Rotation:

1. Nicole Skill Revelation: Uncreated Light + Burst Revelation: Ladder of Divine Ascent
   →
2. Durin Skill Binary Form: Convergence and Division + Skill (enter Light Mode) + Burst Principle of Purity: As the Light Shifts
   →
3. Iansan Skill Thunderbolt Rush + Burst The Three Principles of Power
   →
4. Chasca combo

Nicole's Burst is skippable if Energy isn't available. It doesn't provide as much damage as in Hexerei teams, but Chasca can run into downtime if Nicole doesn't use it. If you don't run into downtime, you can skip it.

With Amplifying Reactions:

Chasca - Citlali - Mavuika - flex (Iansan)

Citlali is nigh required to have a good time with Chasca Melt. There is no other unit that can provide what she does, between the Pyro RES Shred and Cryo + Pyro DMG% buffs.

Mavuika is the best option with Citlali, but Durin can also do the trick. Both Light and Dark mode can work.

Iansan is the best flex slot here, but Bennett and Nicole are also strong. Citlali Durin Nicole works, and Mona can be a strong slot-in here too for a Vaporize team instead of a Melt one.

Example Rotation:

1. Mavuika Skill The Named Moment
   →
2. Iansan Skill + Burst
   →
3. Citlali Skill + Burst
   →
4. Mavuika Burst
   →
5. Chasca combo

There are other teams that Chasca can use decently. Vaporize with Furina, Lunar-Charged with Columbina + Ineffa are a few examples. However, she will generally want to use one of the two structures above. Chasca is essentially a Pyro DMG focused carry most of the time, at least at her best.

Astral Vulture's Crimson Plumage: Chasca’s signature. Her Elemental Skill is able to trigger Swirl, so the ATK% passive is always active, and the differing Element passive will also be always active. Very strong for her, though not necessarily a great generalist bow.

Limited 5* Crit Bows: Bows like Aqua Simulacra and The First Great Magic can be pretty strong, although worse than Crimson Plumage. They’re generally all decent, but not incredible.

Skyward Harp About as good as Amos' Bow. Both are pretty okay. Amos Bow can lose value in a team like Iansan + Nicole.

Flower-Wreathed Feathers: About as good as some of the Limited 5* Crit Bows when used at a high refinement, although it can be quite hard to acquire as a Weapon Banner only weapon. Chasca’s Charged Attacks count as her being in Aiming Mode, making it very strong for her.

Song of Stillness: Technically her best free option with a healer. It’s pretty decent.

Chain Breaker: Natlan craftable, about 1% worse than Song of Stillness in the latter’s ideal conditions, and otherwise a little better. It’s mostly just decent. Makes for a solid free option.

Obsidian Codex: By far Chasca’s best set, without real competition; even the 2pc is fantastic and the best available 2pc to her. Chasca’s teams will generally want to have a character that can use Scroll of the Hero of Cinder City in them most of the time, so if you want to play her and don’t have a set ready, farming that domain will be a good investment.

2p2p combinations ATK % Obsidian Codex Elemental Mastery Pyro DMG: Will hold her over until a strong Obsidian Codex 4pc. Keep in mind that Obsidian 2pc is also her best 2pc effect.

Overview

Chasca is a Charged Attack carry. She has a special Charged Attack that she can access by using her Elemental Skill Spirit Reins, Shadow Hunt to enter her Nightsoul’s Blessing state. This special CA will load 6 Elemental Bullets that are largely based on the Elemental Types of Chasca’s Teammates, with each unique PHEC type making her do more damage and use more Elemental Bullets more consistently, at least at C0.

Chasca’s gameplay itself is generally on the simpler side to execute, although optimizations certainly exist, particularly at C1+. At her simplest, Chasca can simply use her Elemental Skill and hold down the Charged Attack button until her Skill duration ends, occasionally using Burst. However, the mechanics of her Charged Attack can be on the complicated side.

Despite being a Charged Attack carry, none of Chasca’s MVs are in her Normal Attack talent. She doesn’t use her regular NAs or CAs, and her important talent values are in her Elemental Skill talent.

Elemental Skill and Nightsoul's Blessing

Upon casting her Elemental Skill, Chasca will start riding her gun and enter her Nightsoul’s Blessing state, dealing a small amount of Anemo DMG around her in the process. This Skill has a cooldown of 6.5 seconds that begins after Chasca exits this state, and Chasca will generate 5 Anemo Particles when she hits an enemy while in this state.

On cast, Chasca will gain 80 Nightsoul Points. Dashing will consume a large number of Nightsoul and should be avoided. While in this state, Chasca will consume 8 Nightsoul per second, giving her Elemental Skill a maximum of 10 seconds of uptime.

Elemental Bullets

Chasca’s Normal Attacks will become shotgun shots infused with Anemo. These are weak and not worth using. Chasca’s Charged Attack will become ‘Multitarget Fire’. While holding this Charged Attack, Chasca will load ‘Shadowhunt Shells’, up to 6, based on the Elements of her teammates. 2 of these will always be regular Anemo Shadowhunt Shells at C0, whereas 4 will become Shining Shadowhunt Shells of the other Elements.

Shining Shadowhunt Shells deal significantly more damage than regular Shadowhunt Shells. Chasca does not deal a lot of Anemo DMG; her damage is primarily PHEC, depending on the Elemental makeup of the team and Reactions triggered.

There will be at least 1 Bullet of each Elemental makeup. Each PHEC unit will directly convert into 1 Elemental Bullet of the type, so Chasca is guaranteed to convert 3 Shells with 3 PHEC units.

Bullet loading mechanics & PHEC team makeup

Through her Ascension 1 passive: if she’s using 3 different PHEC Elements, Chasca will always convert 1 more Shell into a random Elemental type, with equal chance for all 3 types. If there are 2 PHEC Elements in the team,this becomes a ⅔ chance to load a 4th Shining Shell, still with an equal chance to be either of the 2 types. With 1 PHEC element, this chance becomes only ⅓. The last scenario is not a useful one, and Chasca will generally use either 3 or 2 PHEC Elements in her team; her best tend to be 2 PHEC teams.

C1 lets Chasca load a 5th Shining Shell, and she will also make it so the aforementioned 4th Shining Shell will always be loaded with 2 PHEC Elements in the team.

Additionally with this passive, the number of Elemental Types present in the team will buff Chasca’s damage by 15% / 35% / 65% based on the number of Elemental types present in the team, corresponding to 1 / 2/ 3 different Elements. The Shadowhunt Shells deal damage considered both Nightsoul and Charged Attack damage, and also deal damage of the corresponding Element.

At C0: if Chasca is using 2 Pyro units and 1 Electro unit, 2 Bullets will always be Pyro and 1 will always be Electro, whereas the 4th converted Shell will be randomly either Pyro or Electro (assuming a 4th Shining Shell load). With 3 different PHEC units, Chasca will get 1 Shell of each Element, whereas the 4th (which will always load) will be a random Shell of one of those Elements.

Elemental Burst

Soul Reaper's Fatal Round has an Energy cost of 60 and a cooldown of 15 seconds. Chasca will fire 6 different Elemental Bullets, and for every PHEC teammate, 2 out of 6 will become one of the PHEC types in the team, chosen randomly and at an equal chance. This Burst does not have a ‘unique PHEC’ conditional, so any team with any 3 PHEC units will always make the Burst Bullets be of a PHEC type. This Burst does decent damage, but not enough to be worth building any Energy Recharge for. Use it at the end of Chasca’s Elemental Skill uptime wherever available.

Chasca’s Shells have an order of firing, though this will typically not matter outside of niche scenarios; this is in reverse order of loading. The more important part is which Shells will react: specifically, every other Shell. The 1st, 3rd and 5th Shells are the ones that will be able to trigger Elemental Reactions. The 1st Shell will always be PHEC as will the 3rd, but the 5th will always be Anemo at C0.

Chasca is able to cancel out of her Multitarget Fire early by letting go of the CA button. This will release all Shadowhunt Shells that have been loaded so far, regardless of number. Letting go at certain benchmarks, particularly as soon as the 4th or 6th Bullet has loaded, can lead to doing more damage. At C1 and above, Chasca is now incentivized to fire as soon the 5th Bullet has loaded, as that is the last Bullet to trigger a Reaction.

Chasca can freely move around while in Multitarget Fire’s Aiming Mode. Since she hovers at a pretty good height, she will naturally dodge quite a few attacks by simply flying above them.

Chasca was officially released as a playable 5-star Anemo character in Genshin Impact on November 20, 2024, during the Version 5.2 update.
