What is an HSR Relic Calculator?
The HSR Relic Calculator is an essential tool for Honkai: Star Rail players who want to maximize their character’s performance. Relics are the primary source of power in the late game, but determining if a relic is “good” or “bad” can be confusing. Our calculator takes the guesswork out of the equation by assigning a numerical score to your relics based on their sub-stats and how they align with specific character roles.
Who should use an hsr relic calculator? Primarily, players reaching Trailblaze Level 50 and above who are starting to optimize for the Memory of Chaos (MoC) or Pure Fiction. A common misconception is that a relic must have both Crit Rate and Crit DMG to be viable. While this is true for most DPS characters, DoT (Damage over Time) characters or Break Effect specialists require a different scoring logic, which this tool provides.
HSR Relic Calculator Formula and Mathematical Explanation
The foundation of relic scoring is the Crit Value (CV). This is a standard community metric used to weight the most impactful offensive stats. However, a true hsr relic calculator must also account for ATK%, Speed, and other utility stats.
The core derivation used in this tool is as follows:
- Crit Value: (CRIT Rate × 2) + CRIT DMG
- Weighting: Each stat is assigned a weight from 0 to 1 based on its utility. CRIT stats are the benchmark (Weight 1.0).
| Variable | Meaning | Unit | Weight (Standard DPS) |
|---|---|---|---|
| CR | CRIT Rate | % | 2.0 (CV base) |
| CD | CRIT DMG | % | 1.0 (CV base) |
| ATK% | Attack Percentage | % | 0.75 – 0.85 |
| SPD | Speed | Flat | 2.0 – 2.5 |
| BE | Break Effect | % | 0.5 – 1.0 |

Practical Examples (Real-World Use Cases)
Example 1: The “God Tier” Crit Piece
Imagine you roll a Head piece with: 9.3% Crit Rate, 12.4% Crit DMG, and 4.0% ATK. Using the hsr relic calculator:
- Crit Value = (9.3 × 2) + 12.4 = 31.0
- ATK Contribution = 4.0 × 0.8 = 3.2
- Total Score = 34.2 (Grade A)
Example 2: The Speed Tuned Support
A pair of Speed Boots with 4 Speed (substat), 11% Break Effect, and 3.5% CR. In a Break Specialist build:
- Speed Contribution = 4 × 2.5 = 10.0
- Break Effect Contribution = 11 × 1.0 = 11.0
- Crit Contribution = (3.5 × 2) = 7.0
- Total Score = 28.0 (Grade B)
How to Use This HSR Relic Calculator
- Input Sub-stats: Look at your relic in-game and type the values for Crit Rate, Crit DMG, ATK%, etc., into the corresponding fields.
- Select Template: Choose the “Weighting Template” that matches your character. Use “Standard DPS” for Seele or Jingliu, and “Break Specialist” for Firefly or Boothill.
- Read the Grade: The calculator will instantly provide a score and a grade (D through SS).
- Review the Chart: Look at the visual distribution to see which stats are contributing most to your score.
- Decision: If a relic scores below 20 (Grade C/D), it is generally considered “fodder” unless it completes a necessary set bonus.
Key Factors That Affect HSR Relic Calculator Results
- Base Stat Rolls: Relics start with 3 or 4 sub-stats. A 4-stat starter always has a higher potential score.
- Roll Procs: Every 3 levels, a random sub-stat is upgraded. High rolls (e.g., 3.2% CR) vs low rolls (e.g., 2.5% CR) significantly impact the final score.
- Speed Breakpoints: Speed isn’t just a number; hitting 134, 143, or 160 is crucial for turn frequency.
- Character Synergy: Some characters like Blade scale off HP%, making the standard ATK-based hsr relic calculator less accurate for them.
- Main Stat Relevance: Even a 50CV relic is useless if the main stat is DEF% on a pure DPS character.
- Set Bonuses: Sometimes a weaker individual relic is better if it activates a powerful 4-piece set bonus like “Messenger Traversing Hackerspace”.
Frequently Asked Questions (FAQ)
1. What is a “Good” Crit Value (CV)?
In most hsr relic calculator communities, a CV of 20+ is decent, 30+ is great, and 40+ is legendary tier for a single relic.
2. Does this calculator work for Planar Ornaments?
Yes, the sub-stat scoring logic remains the same for both Cavern Relics and Planar Ornaments.
3. Why is Speed weighted so highly?
Speed allows your character to take more actions per cycle in MoC, which is often a larger damage increase than a few % of Crit DMG.
4. My relic has high DEF% but it’s Grade S? Why?
If you are using a Tank/Support template, defensive stats are weighted higher. Ensure you have the “Standard DPS” template selected for attackers.
5. Should I fodder all Grade D relics?
Usually, yes. However, keep Grade D relics if they have a rare Main Stat (like Energy Regeneration Rate) until you find a better replacement.
6. Does the level of the relic matter?
The calculator evaluates the *current* stats. A level 15 relic will naturally score higher than a level 0 relic because it has had more roll upgrades.
7. How do flat stats affect the score?
Flat ATK, HP, and DEF are generally weighted very low (0.1 or 0) in a professional hsr relic calculator because they provide diminishing returns compared to percentages.
8. What is “Efficiency” in the results?
Efficiency compares your relic’s total score to the theoretical maximum possible rolls for that specific item.
