If you’re building Sunday, the 5-star Imaginary support from Honkai Star Rail, you’re going to want to optimize Sunday relics. Sunday follows the Path of Harmony, meaning his job is to boost his teammates while keeping the team in peak form. Let’s break down the best HSR Sunday relic sets, stats, and alternatives to help you get the most out of this 5-star unit.
What Makes Sunday Special?
Sunday is a powerful support character who increases the team’s Speed and Critical Damage. This makes him perfect for boosting main DPS units, allowing them to deal even more damage and act faster. To make him shine, the right relics are essential.
Best Relic Set for Sunday in HSR
The best relic set for Sunday is the Sacerdos’ Relived Ordeal. This set focuses on boosting Speed and Critical Damage, which are core to Sunday’s support abilities.
- 2-Piece Bonus: Increases Speed by 6%.
- 4-Piece Bonus: Using a Skill or Ultimate on an ally boosts their Critical Damage by 18% for 2 turns. This bonus can stack up to two times for a total of 36% increased Critical Damage.
This set works perfectly with Sunday’s kit, allowing him to make teammates faster and deal devastating damage.
Alternate Sunday Relics in Honkai Star Rail
If you don’t have a full Sacerdos’ Relived Ordeal set, here are some alternatives as Sunday relics:
- Messenger Traversing Hackerspace (2-Piece) + Sacerdos’ Relived Ordeal (2-Piece): This combination gives a 12% Speed bonus, helping Sunday act faster to support the team.
- Eagle of Twilight Line (4-Piece): Increases Break Effect by 20% and regenerates 10 Energy after Weakness Break. This is less focused on support but can be useful in specific setups.

Best Stats for Sunday
Relic stats are just as important as the sets. Here’s what you should prioritize:
- Body: Critical Damage (%)
- Feet: Speed
- Planar Sphere: HP (%)
- Link Rope: Energy Regeneration Rate (%)
Sub-Stats to Look For:
- Critical Damage (aim for 200% or higher)
- Speed (at least 134, but slightly slower than the DPS for optimal support)
- Effect Resistance (50% or more to avoid debuffs)
- HP (%) for survivability
Best Planar Ornaments
Sunday’s Planar Ornament set should focus on energy regeneration and boosting his Ultimate. The best option is Lushaka, the Sunken Seas.
- Effect: Increases Energy Regeneration Rate by 5%. When Speed is 145 or higher, increases Ultimate Damage by 15%.
This set complements Sunday’s support role by ensuring he can frequently use his Ultimate to provide consistent buffs to the team.
Well, Sunday is a game-changer for teams that rely on high DPS characters. His ability to increase Speed and Critical Damage makes him invaluable in difficult battles, especially against tough bosses. By equipping him with the right relics and stats, you ensure he can perform his role perfectly.
So, the Sacerdos’ Relived Ordeal set, combined with Speed and Critical Damage-focused stats, will maximize his support potential. Pair that with the Lushaka, the Sunken Seas Planar Ornament, and you’ve got yourself a top-tier support unit.
