Crit Rate and Crit DMG do nothing for you in isolation. A character with 100% Crit Rate and 50% Crit DMG (the base value) crits every hit for a pathetic bonus. A character with 5% Crit Rate and 300% Crit DMG lands one monster hit roughly every twenty swings and whiffs the rest. Damage lives in the product of the two, and the product is largest when the two are kept in proportion. That proportion is the whole game, and it has a shorthand: aim for a Crit Rate to Crit DMG ratio of about 1 to 2.
Every character in Genshin starts with 5% Crit Rate and 50% Crit DMG. Your artifacts, weapon, and ascension bonuses have to move both numbers up together. Get the balance right and you are squeezing the most damage out of the substats the game grudgingly hands you. Get it wrong and you are throwing away rolls.
The target, in one table
| Investment level | Crit Rate | Crit DMG | Notes |
|---|---|---|---|
| Bare minimum | 50% | 100% | Playable, not optimized |
| Solid | 70% | 140% | The classic "70/140" benchmark |
| Well-built | 80% | 160% to 200% | Endgame-ready for most DPS |
| With a crit buffer | 60% to 65% | 120%+ | Let the support carry the Rate |
The "70/140" figure is the one to memorize. It is the point where most builds start feeling like they crit reliably without wasting stats, and it is realistic to hit on a character you actually farm for. Everything past it is refinement.
Why 1:2 and not 1:1
Think of your total damage multiplier from crits as 1 + (Crit Rate x Crit DMG). Every point you can spend goes into either Rate or DMG, and the product of two numbers with a fixed sum is largest when they are balanced against their point cost. In Genshin, one roll of Crit DMG is worth roughly twice as much (about 7.8% at the high end) as one roll of Crit Rate (about 3.9%). So a single artifact substat line gives you either "one unit" of Rate or "two units" of DMG.
Balancing the value, not the raw percentage, is what produces the 1:2 ratio. When your Crit DMG is about double your Crit Rate, one more roll of either stat adds almost the same amount of real damage, which is the mathematical signature of an optimized build. Stray too far in either direction and the next roll of the overweighted stat starts giving you less than the underweighted one would.
Crit Value: the number that scores an artifact
Crit Value (CV) is the shorthand the community uses to grade a piece of gear:
CV = (Crit Rate % x 2) + (Crit DMG %)
A five-star artifact can roll crit substats up to nine times across its life. As a rough grading scale for a single artifact's crit substats:
- Under 10 CV: filler, feed it to something or replace it.
- 10 to 20 CV: usable while you farm for better.
- 20+ CV: a genuinely good piece.
- 40+ CV: a trophy. Screenshot it.
Chasing "50 CV artifacts" is the endgame grind. You do not need them to clear content, but they are the difference between comfortably clearing the Spiral Abyss and struggling on the timer.
Where each stat comes from
You build the ratio from four sources, and knowing which source gives what keeps you from double-dipping into the same stat.
- The Circlet main stat. Your single biggest lever. A Circlet rolls either Crit Rate (up to 31.1%) or Crit DMG (up to 62.2%). Pick the one that fixes your current imbalance. If your weapon already pours in Crit DMG, use a Crit Rate Circlet, and the reverse.
- The weapon substat. Many five-star and four-star weapons carry Crit Rate or Crit DMG as their secondary stat. A Crit DMG weapon (say, a Wolf's Gravestone alternative or a Widsith) means you should lean your Circlet and rolls toward Crit Rate to compensate.
- Ascension bonuses. Some characters ascend into Crit Rate or Crit DMG at level 80/90, which quietly solves half your ratio for free. Check your character's ascension stat before you farm, because it changes which Circlet you want.
- Artifact substats. The grind. Every non-crit main-stat slot (Flower, Feather, Sands, Goblet) can roll Crit Rate and Crit DMG as substats. This is where the "1:2 by value" rule does its work.
The one-minute build check
When you finish gearing a character, do this before you move on:
- Add up total Crit Rate and total Crit DMG from the character screen (this already includes ascension and weapon).
- Is Crit DMG roughly double Crit Rate? If DMG is far higher than 2x Rate, you are crit-DMG heavy and your next Circlet or rolls should go to Rate. If Rate is high but DMG is low, the reverse.
- Are you at least at 60% to 70% Rate? Below that, your big hits are inconsistent and the Abyss timer will punish you.
When to break the 1:2 rule
The ratio is a default, not a law. Deliberately ignore it in these cases:
- A crit buffer is on the team. If you run a support who hands out Crit Rate (a common pattern for on-field carries), you can drop your personal Crit Rate to 50% to 60% and pour everything else into Crit DMG. The buff finishes the ratio for you, and any Rate past the point where you crit "enough" is wasted.
- Ascension already gives Crit Rate. A character that ascends into 24% Crit Rate is starting with 29% before artifacts. Feeding them more Rate is often wrong; go Crit DMG Circlet and DMG rolls.
- The reaction does not crit. This is the big one, and it is worth its own section.
Reactions change everything
Not all damage cares about crit.
- Amplifying reactions (Vaporize, Melt) multiply your attack's damage, and that attack can crit. Crit ratio matters as much here as anywhere. A Melt or Vaporize carry wants the full 70/140-plus treatment.
- Transformative reactions (Overload, Superconduct, Electro-Charged, Swirl, and by default the Dendrite reactions like Bloom, Hyperbloom, and Burgeon) scale off Elemental Mastery and your level, and by default they cannot crit. Building Crit Rate and Crit DMG on a character whose damage comes almost entirely from these reactions is a waste. Build Elemental Mastery instead.
The trap is a hybrid character who does some direct damage and some transformative reaction damage. For them, split the difference: enough crit to make the direct hits count, but not so much that you starve the Mastery that powers the reactions. When in doubt for a reaction-focused unit, Mastery and Energy Recharge usually beat a marginal crit roll.
A realistic farming order
You will not roll a perfect ratio in a week. Prioritize like this:
- Get every artifact main stat correct first (Sands, Goblet, Circlet). A wrong main stat cannot be fixed with substats.
- Choose the Circlet that patches your ratio, given your weapon and ascension.
- Farm the correct set (use the best characters guide and team-building guide to confirm the set), keeping pieces with double crit substats even if the other stats are mediocre.
- Only chase the last few CV once the character clears the content you care about.
And do not let the ratio become an excuse to burn all your Resin on one character. A team of three 60/120 units clears far more than one 90/220 carry surrounded by unbuilt supports.
Quick answers
What is the ideal crit ratio in Genshin Impact? About 1 Crit Rate to 2 Crit DMG. The practical benchmark is 70% Crit Rate and 140% Crit DMG, scaling toward 80/200 on well-built damage dealers.
Is Crit Rate or Crit DMG more important? Neither on its own. Raise whichever one is lagging your 1:2 ratio. If a teammate buffs your Crit Rate, favor Crit DMG.
Do all characters need crit? No. Characters whose damage comes from transformative or Dendrite reactions (Hyperbloom, Overload, Superconduct) want Elemental Mastery, not crit, because those reactions do not crit by default.
