Sunday Build Guide

Role & Strengths

When you use Sunday in Honkai: Star Rail 3.8, you get a character who can boost your whole team. Sunday stands out because he helps your main damage dealer and their summons attack more often. This means your team can deal a lot more damage in tough fights. You will notice that Sunday’s skills make your team faster and stronger, especially if you use characters who rely on summons.

Here’s what makes Sunday so powerful in high-level content:

• Sunday increases the damage and critical damage for your main DPS, especially those with summons.
• His Skill lets your DPS and their summon take another turn. This can double their damage in one round.
• His Ultimate gives your team more energy and boosts critical damage. This helps you use big attacks more often.

If you want to clear hard stages or beat bosses, Sunday gives your team the edge. Many top players use him in their Build Guide because he fits well with both summon teams and hypercarry teams. You can count on Sunday to make your team shine.

Tip: Try pairing Sunday with characters like Aglaea or Jing Yuan. You will see a big jump in your team’s damage!

Key Stats

To get the most out of Sunday, you need to focus on the right stats. Picking the best stats helps Sunday support your team and keep up with the hardest content. Top player guides suggest you look for stats that boost critical rate, critical damage, and energy regeneration. To maximize your relic farming efficiency, check our Relic Farming Guide (Note: linking to Genshin farming guide as closest match for general resource management concepts).

Here’s a quick-reference table to help you with your Build Guide:

Key Stat	Quantity	Event Tokens	Description
Self-Modeling Resin	12 units	960	Top priority for relic optimization, crucial for builds with optimal CRIT Rate/CRIT DMG.
Stellar Jade	1,600	400	Great for pulls, helps you get more Light Cones or Eidolons for Sunday.

When you build Sunday, focus on relics that give you more CRIT Rate and CRIT DMG. Energy Regeneration is also important. This way, Sunday can use his skills and Ultimate more often, helping your team win more battles.

If you follow this Build Guide, you will see Sunday become a key part of your team. He makes your main damage dealer stronger and keeps your team moving fast. Remember to check your stats and upgrade the right relics for the best results!

Trace & Materials

Trace Priority

If you want Sunday to shine in your team, you need to level up the right traces first. Traces make Sunday’s skills stronger and help your team win tough battles. You should focus on his Skill and Ultimate before anything else. These two traces give your main DPS more attack power and boost their critical stats. Here’s a quick table to help you see which traces matter most:

Trace	Priority & Explanation
Skill	★★★★★ – Highest Priority. Leveling this up boosts the ATK% Sunday gives your team.
Ultimate	★★★★★ – Highest Priority. Upgrading this increases CRIT Rate, CRIT DMG, and damage.

Tip: Always max out Sunday’s Skill and Ultimate first. You will notice a big difference in your team’s damage output.

After you finish these, you can work on Sunday’s Talent and Basic ATK. These help a little, but they do not give as much power as the Skill and Ultimate.

Materials List

You need a lot of materials to make Sunday strong. If you want to ascend him and unlock all his traces, you should start farming early. For more on farming routes and efficiency, see our Energy Management Guide. Here’s a handy table with everything you need:

Ascension Materials	Total
Chordal Mirage	65
Firmament Note	15
Harmonic Tune	15
Traveler’s Guide	15
Credits	308,000

All Trace Node Materials	Total
Harmonic Tune	18
Firmament Note	41
Chordal Mirage	69
Tracks of Destiny	12
Traveler’s Guide	56
Credits	3,000,000

You can get Chordal Mirage from the Shape of Timbre: Stagnant Shadow. Just beat the Tomorrow in Harmonious Chords enemy. If you need Firmament Note, clear the Calyx (Crimson): Bud of Harmony. You can also use the Synthesizer to swap for some materials if you are short.

If you follow this Build Guide, you will have Sunday ready for any challenge. Make sure to keep farming and upgrading so your team stays ahead!

Light Cones

Best 5-Star Options

You want Sunday to shine, so picking the right Light Cone matters a lot. The top 5-star Light Cones give you more energy, skill points, and damage. For a more detailed breakdown of 5-star Light Cone value, visit our Light Cone Value Guide. Here’s a quick look at the best choices:

Light Cone Name	Effect Description
A Grounded Ascent	Regenerates 6 Energy for allies when you use Sunday’s Skill or Ultimate. Increases their damage by 15% for up to three turns. Recovers a Skill Point after every two uses.
Earthly Escapade	Raises CRIT DMG by 32%. Gives all allies 10% CRIT Rate and 28% CRIT DMG while Sunday has Mask.
But The Battle Isn’t Over	Boosts Energy Regeneration Rate by 10%. Regenerates a Skill Point when you use Ultimate on an ally. Increases the next ally’s damage by 30% for one turn.

You get the most out of Sunday with A Grounded Ascent. This Light Cone helps you use your Ultimate more often and keeps your team’s damage high. It also gives you skill points, so you never run out during long fights. Earthly Escapade works well if you want more critical stats for your whole team. But The Battle Isn’t Over is great for energy and skill point management, making it a solid pick for many teams.

Tip: Try to match your relic and ornament sets to your team’s needs. If your DPS is fast, focus on Speed and Crit Damage. If you need more energy, go for Lushaka or Sprightly Vonwacq.
